CHARTERS TOWERS REGIONAL COUNCIL

TOTAL MANAGEMENT PLAN FOR WATER SUPPLY AND SEWERAGE SERVICES

VERSION 1 - NOVEMBER 2009 EXPLANATORY NOTE

In 2008 the Dalrymple Shire Council and City Council were amalgamated to become the Charters Towers Regional Council (CTRC). When combining the assets of both councils both the Total Management Plans (TMP) and Strategic Asset Management Plans (SAMP) from each council required updating to prepare a new TMP document.

A change to the governing body has lead to various legislative alternations. Council is now required to include in its planning a SAMP, a System Leakage Management Plan (SLMP) and Drought Management Plan (DMP). A DMP and SLMP were prepared for CTRC in May 2008 and revised following comments in September 2008.

Dalrymple Shire Council had prepared a SAMP, while the Charter Towers City Council had prepared a TMP. Both documents included gaps in the information which are being closed as information is found.

The organisation of this TMP document is designed as a “living document” to assist engineering staff and management. Through careful planning it allows information in the document to be easily updated, as well as simplifies the annual reporting and review process.

The TMP has been updated in compliance with the TMP Development Guide 2001.

DOCUMENT AND VERSION CONTROL

The TMP is a controlled document. The signed document and version control sheet at the front of the document indicate the current version. Information within the appendices is to be updated in compliance with Section 7 of the Guideline. It requests: • Action Plans – 6-12 months (review with annual reporting requirement). • Sub-plans – 1-3 years. • Associated policies – 1.5 years. • Business management plan – 1-3 years.

Revisions to individual pages or sections of the TMP will be indicated by a revision number and date added to the footer of the page, as well as notation in the version control table.

From the Mayor

It is most desirable and very satisfying to provide good, clean, adequately operating services and facilities for a community.

Charters Towers Regional Council has as one of its goals:

• To efficiently provide clean and safe water for usage across all needs and functions of our communities.

To this end, our Asset Management team has compiled a comprehensive Total Management Plan to cover all aspects of the functions of all water and sewerage related services including its reticulation, treatment and extraction processes.

I fully support the Total Management Plan and look forward to the efficiencies that it helps to maintain.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Part A: Overview Version 1 – November 2009

1 INTRODUCTION

1.1 PURPOSE

The purpose of this Total Management Plan (TMP) is to provide: • A total picture of how Charters Towers Regional Council (CTRC) currently manages water supply and sewerage services for the and towns of Greenvale, Pentland and Ravenswood. • Details of the management strategies and priorities currently being used to drive cost efficiencies and to improve the service. • Details of the major issues facing the Council in the provision of these services and the strategies being pursued to ensure continuing high quality services into the future.

1.2 STRUCTURE OF THE PLAN

The TMP is structured around a hierarchy of inter-related documents as outlined in Figure 1.1. This figure shows the guideline structure of the TMP and the relevant sections of the CTRC TMP.

Figure 1.1: Structure of TMP

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Part A: Overview Version 1 – November 2009 Page 1 Part A of the TMP is an overview which outlines the structure, background, description of the schemes, the major management challenges, a summary of the strategic framework and the management responsibilities for implementation of the plan.

The strategic basis of the TMP which is summarised in Section 5 “Summary of Strategic Framework” outlines the goals, objectives and management strategies for Appendices (Sub-Plans) that form the TMP. The appendices allow continual updating and expansion as the plans develop.

The TMP tightly links Council’s corporate and operational planning processes. The goals, objectives and strategic objectives outlined in the summary framework have been developed to directly support major strategic objectives in Council’s Corporate Plan.

2 BACKGROUND

CTRC has a combined annual water supply and sewerage budget of around $5,200,000, and operates related infrastructure with a current replacement value of approximately $80 million.

This is the first comprehensive TMP that CTRC has produced for Water Supply and Sewerage (WSS) services since the amalgamation of the Charters Towers City Council and Dalrymple Shire Council.

Over recent years, Dalrymple Shire Council has developed a Strategic Asset Management Plan (SAMP) for water and sewer. Both councils had separate asset registers, operations manuals and other documentation for the respective water and sewerage systems. The TMP collates the information from a number of separate documents into a comprehensive plan and provides a new SAMP for the combined council.

The goals, objectives and strategies of the TMP have been developed to directly support major strategic objectives in Council’s Corporate Plan. It presents consistent information on the WSS services and networks. Not all of the information will be available for review and confirmation for accuracy when the TMP for the Regional Council is first developed. However, due to the “living document” formatting, information can be updated without re-printing the whole document at each change.

Charters Towers Regional Council Part A: Overview Total Management Plan for Water & Sewerage Services Page 2 Version 1 – November 2009

3 DESCRIPTION OF SCHEMES

CTRC operates WSS schemes in Charters Towers, Greenvale, Ravenswood and Pentland.

Figure 3.1: Locality Plan from Google Earth

There remains significant work to combine the schemes for the towns into a single format with readily accessible data. Asset data is available but has not been collated at the time of writing due to difficulties of extracting the data from the Asset Databases. Tables 3-3 to 3-5 will be updated as the information on assets is collated and confirmed during the development of a TMP covering the new amalgamated council area. For the purposes of this document the lack of data is not significant and it is considered better to leave blank spaces rather than include data which may be proven inaccurate. The schemes have been described from data made available by Council staff.

In this plan some population figures for the communities served have been taken from data supplied by CTRC and are identical to data used in other water asset management documents. While on the surface there are differences in population figures between this information and the data found from the Australian Bureau of Statistics, it is likely that the boundaries of the water service area and the statistical areas are different. Assumptions drawn from water meter records are still to be confirmed from other Council records and shall be completed when the TMP for WSS is prepared.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Part A: Overview Version 1 – November 2009 Page 3 Charters Towers’ water supply serves a population of approximately 8, 000. It includes the service area of Charters Towers City Council and the surrounding edges of the city previously in Dalrymple Shire. Water is sourced from two main reservoirs on the Burdekin River (The Burdekin Weir). Water is treated prior to storage then reticulated throughout the city. This network is maintained in good condition and has been calculated at being around 25 years.

Greenvale water supply is sourced from the Burdekin River from 4 spears. Water is pumped to storage with chlorine injection for disinfection, where it receives minimal treatment. Water is reticulated to the township through a network believed to be around 40 years.

Ravenswood water supply is originally sourced from the Burdekin River by Carpentaria Gold. Water is pumped to a “turkey nest” dam before Carpentaria Gold provides water to the township. The assumed age of this network is 10 years and is owned and maintained Charters Towers Regional.

Pentland Water supply is sourced from ground water in the Glen Houghton bore field. Two bores pump water to a small treatment plant where water is disinfected before reticulation to the township. The average age of the network is assumed to be around 50 years. As this scheme is a groundwater recharge system it is included in the document for completeness but no additional investigation is required unless conditions change.

Schematics of each of the four water supply schemes are included at Appendix A

Each of the four supply schemes are to be treated as district metered areas for the purposes of leak detection and economic analysis of leak reduction methods.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Part A: Overview Version 1 – November 2009 Page 7 4 MAJOR CHALLENGES

4.1 AGEING INFRASTRUCTURE

Water Supply

The water supply network is generally in good condition. This is evidenced by the repair and replacements being undertaken by the maintenance staff.

One of the main concerns for all the water supply systems in North is the amount of Asbestos Cement pipe in the water supply network. The Charters Towers Networks are no different. While the average life of asbestos cement pipe was originally considered to be approximately 70 years, experience in other networks is indicating that a higher failure rate in this product may be expected to begin within the next 10 years. Replacement of this pipe is a concern because of the Occupational Health and Safety implications.

Failure and repair data of the network indicate small diameter service lines (between main and property boundary) are failing at a high rate. Repair of these failures is currently being undertaken, however, a program to replace service lines may be considered as a long term replacement strategy. The SLMP and associated analysis confirm more attention needs to be placed on the water supply network.

Sewerage

The sewerage scheme for Charters Towers is robust and provides adequate treatment for the waste water in the town of Charters Towers. The effluent from the treatment plant consistently meets the EPA requirements for the quality of the discharged effluent from the treatment process.

The other smaller communities rely on individual “On-site” disposal systems. The Greenvale community has a small community package treatment plant, but for the purposes of asset management the system is considered to be an “On-site” disposal system.

4.2 INFORMATION MANAGEMENT

The performance of Council’s assets can only be confirmed through decisions made by managers and elected members evaluating relevant, accurate and timely information. For eligibility of work subsidies, Council needs to demonstrate to Department of Natural Resources & Mines (DNR&M) effective implementation of the TMP.

Various regulatory authorities require regular monitoring and reporting on the quality of water supply and sewerage treatment. However, existing information management procedures do not provide adequate information to enable a sound analysis of the performance of the water and sewerage systems. The challenge is to implement a comprehensive information collection and management system, and to implement regular reporting on the performance indicators identified in this document.

4.3 WATER DEMAND MANAGEMENT

The water consumption level in Charters Towers is considered typical for rural/mining communities in the tropics. Available data suggests that there is a low proportion of Non-Revenue Water (NRW) in Charters

Charters Towers Regional Council Part A: Overview Total Management Plan for Water & Sewerage Services Page 8 Version 1 – November 2009 Towers, creating a challenge in ensuring that the level of NRW is maintained at its current low level while encouraging conservation of water. The SLMP (Appendix N) addresses these issues.

4.4 EFFLUENT DISPOSAL

The effluent from the waste water treatment plant is discharged both to Mossman Creek and also used for irrigation. Currently the discharge to the creek is 70% of the effluent discharged and the reuse component is approximately 30%

4.5 FINANCIAL MANAGEMENT

A considerable amount of financial pressure is likely to be placed on the Councils to maintain the value of the infrastructural assets. The impact of this pressure is to allow sufficient funds in the budget to manage loss of service potential in the infrastructure as well as improve the

Currently the Queensland Government will subsidise many of the justified improvements to the water supply and sewerage schemes in rural communities. The financial challenge to Council will be to continue to prudently manage its existing water and sewerage infrastructure to meet Council health and environmental requirements and community expectations in a financially responsible way.

4.6 HUMAN RESOURCES

The most significant challenge for CTCR is the issue of attracting, recruiting and maintaining technical and water related trades staff. Currently the city has sufficient staff to meet the needs of the community, however with the changing economic and job market demands for technical personal will continue to place stresses on the community.

5 SUMMARY OF STRATEGIC FRAMEWORK

This TMP is a comprehensive plan of delivery of water and sewerage services. The strategic elements of the plan are consistent with Council’s Corporate Plan. The significance of the various plan elements are outlined below, followed by a summary of the plan strategic framework in Table 5.1.

Management Focus For purposes of structuring the TMP, service delivery has been considered in terms of a number of management focus areas. Each focus area of major activity has a related goal and allows substantial progress in fulfilling Council’s role as a service provider.

Sub-plans (Appendices) Each sub-plan or Appendix represents one aspect of service delivery illustrating significant independent opportunities for council to achieve its managerial strategy goals.

Action For every strategy listed for a sub-plan, a list of actions has been developed. These actions have been incorporated into a single improvement plan in Appendix V. The actions are a defined set of activities which include target completion dates and management responsibilities for implementing the action.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Part A: Overview Version 1 – November 2009 Page 9 Performance target The performance target is a defined value for an action council aims to achieve. The TMP has been developed to be implemented on a rolling 3-year basis, with an annual (or more frequently as required) review of the strategic framework and individual appendices (sub-plans). Performance targets are set in Appendix R.

TMP FOR WATER SUPPLY AND SEWERAGE SERVICES INTRODUCTION

FOREWORD

From the Mayor

Chmters Towers Regional Council has a m1ss1on to actively promote the region as an attractive and prosperous m·ea while maintaining for our citizens such amenities that will provide a quality of life of the highest standard. The Council aims to be responsible and progressive in its management and values employees, teamwork, continuous improvement and the quality of the services it provides.

Council aims at providing cost-effective and high quality water supply and sewerage services within the region. These services are essential for the maintenance of the lifestyle and public health of our resident population and tourists. The continued provision of quality, cost-effective service to ratepayers requires Council to:

• maintain existing infrastrncture and renew it as it reaches the end of its economic life; • continue to improve the efficiency of operations; and o manage the water supply and sewerage functions in an environmentally responsible and sustainable mam1er.

Management of water supply and sewerage is becoming more complex and requires effective management for Council to achieve its mission. This Total Management Plan suppmts Council's Corporate Plan in outlining the cmTent status and management strategies for water supply and sewerage services.

Our Total Management Plan identifies how Council officers will address important issues in an orderly and cost-effective manner well before they become problems, while continuing to focus on providing quality, affordable services to the community.

I fully support this Total Management Plan and look forward to its successful implementation by management and staff of Council.

LEGISLATIVE, OTHER REQUIREMENTS, RELATIONSHIPS WITH OTHER PLANNING DOCUMENTS AND WITH OTHER ORGANISATIONS

1 LOCAL GOVERNMENT ACT

The Local Government Act empowers the Council to create, operate and maintain assets for the purpose of meeting community need.

2 WATER ACT

The most significant legislation in Queensland relating to Water and Waste Water supplies is the Water Act (2000). The most recent revision of the Water legislation in 2008 was the introduction of The Water (Safety and Reliability) Act 2008. The key provisions which impact on the required Service Provider management plans and reporting requirements are now included in the transferred to the Water (Safety and Reliability) Act 2008.

The Total Management Plan for Water and Sewerage Assets is one part of the management strategy for the effective use of water and wastewater in Queensland. Although the TMP of itself is not a requirement of legislation this TMP includes all of the elements which are required by legislation and provides the framework for reporting and holding information relating to the water and sewerage asset.

The Strategic Asset Management Plan is to be compiled from the information in this Total Management Plan. This document sets out at Appendix C how the parts of the TMP meet the legislative requirements of the Strategic Asset Management Plan. A Strategic Asset Management Plan has been collated from the appendices and is provided as a separate document for review.

It is a requirement for water service providers to provide an Annual Report and sets out minimum reporting requirements. The Annual Report on the Strategic Asset Management Plan is intended to: • Be a reference document for the Department of Natural Resources and Mines (NR&M) (now part of DERM) – the regulator – as well as customers, in reviewing the performance of the service provider in supplying WSS services. • Provide a summary of the actions that have been undertaken by the service provider in implementing the strategies outlined in the SAMP.

One of the parts of this TMP is the provision for holding the information required by the Annual Report. Annual Reports are also held in the document at appendix X.

3 REVIEW OF LEGISLATIVE REQUIREMENTS

For Local Governments, the Water Supply (Safety and Reliability) Act 2008 contains the specific requirements for reporting and review of the plans required by legislation these are listed below with reference to the sections of the Water Supply (Safety and Reliability) Act 2008.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix A Version 1 - December 2008 Page 1 For registered service providers, that requires:

Part 4 Div. 1 • Service Area Maps to be annually updated. • Audit and review of SAMP, CSS, DMP SLMP and DWMP performance to be completed on a regular basis. Part 4 Div 4 • An Annual Report based on the review of plans (SAMP, CSS, DMP SLMP and DWMP) performance to be prepared and issued to the regulator. Part 4 Div 9 • A System Leakage Management Plan (SLMP). Part 4 Div. 2 • A Drought Management Plan (DMP.) Part 4 Div. 6 • A Drinking Water Management Plan (DWMP) Part 4 Div. 3

4 ANNUAL REPORTING REQUIREMENTS

4.1 ANNUAL REPORTS

Section 141 of the Water (Safety and Reliability) Act 2008 covers the requirements for the information required in the annual report.

The Information in the Annual Report prepared for the purpose of documenting the progress of the SAMP, SLMP DMP and DWMP must:

• Measure the service provider’s performance for the financial year against the SAMP. This includes documenting form the CSS requirements: - Actual levels of service achieved. - An appropriate confidence grading for the data reported. - Any statements qualifying the data reported. • Document actions taken by the provider to implement the management plans, including: - Reasons for failing to undertake a particular action nominated by the service provider for this reporting period. - Application of funds in accordance with the proposed financial arrangements for implementing the SAMP. • Document the outcomes of any regular reviews, including how the service provider has addressed issues raised by the review. • Provide an overview of the findings and recommendations of audit reports given to the regulator in this reporting period.

The CTRC Report is found in Appendix X.

Charters Towers Regional Council Appendix A Total Management Plan for Water & Sewerage Services Page 2 Version 1 - December 2008 4.2 LOCAL GOVERNMENT ANNUAL REPORT

Local government bodies are required, under the Local Government Act 1993, Section 531, to prepare an Annual Report, outlining the overall performance of the organisation over the financial year. It is a requirement under the Local Government Act that the Annual Report be adopted by the 30 November, in the year after the end of the financial year to which the report relates.

Sections of the Water Supply (Safety and Reliability) Act 2008 indicated above now specify the reporting requirements for matters relating to the supply of water services.

5 HEALTH ACT

The Health Act and regulations requires Local Authorities to provide and maintain ‘sanitary works’. This includes drainage works (stormwater), sewerage works and works for collection.

The Health Act empowers the Local Governments to inspect and report on matters relating sanitary services and to issue notices to owners relating to unsanitary conditions.

It also empowers Councils to make bylaws covering conditions to be observed in the construction and approval of pipes and drains. In CTRC the Environmental Health Officer has primary responsibilities under the Act.

The Fluoridation of Water Supplies Act empowers Local Governments to add Fluoride to Public Water Supplies. However, Fluoride is not added to public water supplies in CTRC. The Queensland Government is introducing legislation to ensure that Councils add fluoride to water where possible.

6 ENVIRONMENTAL MANAGEMENT ACT

The Environmental Management Act and regulations requires Local Authorities to obtain and maintain licenses and permits to manage nuisance to the environment from discharge of contaminants.

The information is held in an Integrated Environmental Management System. This plan refers to the IEMS as it relates to land designation, discharge requirements for environmentally sensitive activities.

7 HEALTH & SAFETY ACT

The Council must ensure the safety of the public and all workers (including contractors) when carrying out works.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix A Version 1 - December 2008 Page 3 8 BUILDING CODE

The Building Code of Australia requires provision in any dwelling house of an adequate and convenient supply of wholesome water; suitable appliances for the disposal of refuse water and sufficient sanitary services. This code also covers matters relating to fire protection in commercial buildings and establishments.

9 COUNCIL BY-LAWS AND POLICIES

The CTRC is required to develop policies and bylaws to manage activities within the region. The CTRC policy document contains a number of policies applicable to the supply of its various services.

There are presently no specific Council Bylaws relating to water supply or waste water disposal. There are council regulations relating to water use and conservation.

There are number of financial policies (fees and charges) and a copy of these is included in Appendix T.

AN OVERVIEW OF EVERY SEPARATE PUBLIC WATER SUPPLY AND WASTE WATER SYSTEM PROVIDED BY CHARTERS TOWERS REGIONAL COUNCIL

1 INTRODUCTION

This section outlines the components of the water supply and waste water schemes. For each scheme, it details the components, condition and performance issues, and scheme-specific information issues.

2 PURPOSE OF WATER / WASTEWATER SUPPLY ASSET COMPONENTS

Table B-2.1: Purpose of Water / Wastewater Supply Asset Components

Asset Purpose Component

Water source To extract sufficient quantities of water from the water source to meet demand projections. To be achieved in a process that secures water is free from contamination, is reliable and complies with water licence conditions. Note: The abstraction of water from natural sources is constrained by the Water Act 2000. The Council holds licenses for each water scheme which specifies the quantity and conditions relating to the draw-off of water Water To reliably produce water meeting National Health and Medical Research Centre (NHMRC) Treatment plant guidelines in sufficient quantities to meet projected demands. (At present there is no requirement for water treatment in Charters Towers City) Wastewater To treat wastewater from the sewerage system to allow discharge in accordance with appropriate Treatment Plant environmental conditions and relevant licences. Water storage To provide sufficient reserves of uncontaminated water to ensure levels of service are maintained and to mitigate risks associated with asset failure (head-works, treatment or trunk mains) or major fires. Pump stations To reliably provide sufficient energy to transport the water to a higher level and/or to overcome the effect of friction losses through the pipelines and fittings so that desired pressure and flows are delivered. To convey sewage throughout the sewer reticulation network towards the wastewater treatment plant. Pipe reticulation The purpose of the water reticulation network is to distribute water from service reservoirs to supply network points for each customer reliably in sufficient quantity to meet peak demands and fire fighting needs, and in a manner which protects water from contamination. The purpose of the sewer reticulation network is to convey sewage from connected properties to the wastewater treatment plant. The networks consist of: • Rising (pump) mains – generally transport water from pump stations to reservoirs (trunk mains as described below), but also to transport raw water from bores, wells or infiltration galleries to

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix B Version 1 – November 2009 Page 1

the treatment plants in some schemes (raw water mains as described below). • Rising (pump) mains also used to convey sewage from low points in the reticulation network. • Falling (gravity) mains- other (non-rising) pipelines including: • Raw water mains - transport water from the head-works to the treatment plant (if any) • Trunk mains - transport water from the treatment plant (if any) to reservoirs • Feeder mains - transport water from reservoirs to the distribution network of service pipes • Service mains – transport water from feeder mains to the connection point of individual properties. • Rider mains – provide service connections to the opposite side of the street to the service mains and allow more flexibility in isolating leaks. Fittings Valves are installed to isolate sections of the reticulation network to minimise the impact of pipe failure and facilitate network repairs. Hydrants are used to draw off water from water mains for fire fighting purposes, flow testing, scouring pipes to remove sediments and to flush ‘dead’ sections of the network. Water meters measure the water flows for the purpose of monitoring water usage, water losses and charging for extraordinary supply.

Charters Towers Regional Council Appendix B Total Management Plan for Water & Sewerage Services Page 2 Version 1 – November 2009 3 OVERVIEW OF SCHEMES

In this plan, some population figures for the communities served have been taken from data supplied by CTRC and are identical to data used in other water asset management documents. While on the surface there are differences in population figures between this information and the data found from the Australian Bureau of Statistics, it is unlikely that the boundaries of the water service area and the statistical areas are different. Assumptions drawn from water meter records are still to be confirmed from other Council records and shall be completed when the TMP for Water and Sewer is prepared.

Charters Towers’ water supply serves a population of approximately 9400. It includes the service area of Charters Towers City Council and the surrounding edges of the city previously in Dalrymple Shire. Water is sourced from weir storage on the Burdekin River (The Burdekin Weir) and is treated prior to storage in two main reservoirs. Water is reticulated throughout the city from the reservoir storage. This network is maintained in good condition and has been calculated at being 25 years.

Greenvale water supply is sourced from the Burdekin River from 3 deep vertical wells. Water is pumped to storage with chlorine injection for disinfection and minimal treatment. Water is reticulated to the township through a network believed to be around 40 years.

Ravenswood water supply is originally sourced from the Burdekin River by Carpentaria Gold. Water is pumped to a “turkey nest” dam before Carpentaria Gold provides water to the township. The assumed age of this network is 7 years and is owned and maintained Charters Towers Regional.

Pentland Water supply is sourced from ground water in the Haughton bore field. Two bores pump water to a small treatment plant where water is disinfected before reticulation to the township. The average age of the network is assumed to be around 50 years. As this scheme is a groundwater recharge system it is included in the document for completeness but no additional investigation is required unless conditions change.

Schematics of each of the four water supply schemes are included at Appendix A

Each of the four supply schemes are to be treated as district metered areas for the purposes of leak detection, and economic analysis of leak reduction methods.

Headworks Charters Towers Regional Council Maintain the weir at the Burdekin River. The weir has had additional height added in 1995 and will now provide 11 months dry weather storage (8 months supply with no inflow). The city of Charters Towers will remain subject to water restrictions and conservation is required to protect against loss of water from an extended dry season or changes in the temporal patterns due to climate change effects.

Treatment Plant Charters Towers Regional Council maintain a water treatment plant at Wheelers Road.

Storage There are two reservoirs. One is at the end of its useful life and is in that are in a satisfactory condition although there is some leakage evident at high levels. The other reservoir is in good condition. It has been inspected and cleaned are found to have no visual defects or leakage.

Reticulation

A large portion of the reticulation was constructed in the 1950s according the assets register

Service Fittings

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix B Version 1 – November 2009 Page 7 Data collection on these assets while considered essential is not a high priority because the network is relatively new (less than 50 years). Services fittings and valves have been replaced on as required basis.

The local fire brigade conduct practice drills using a selected number of hydrants.

Charters Towers Regional Council are responsible for the maintenance of the hydrants

4.3 ASSET PERFORMANCE

Water Quality The water quality from the Charters Towers Treatment Plant is very good. The water is free from coliforms and its quality typically meets the NHMRC guidelines.

Water Capacity The scheme operates with sufficient capacity to supply the peak demands made at present.

Economic Efficiency To provide operational and maintenance savings, all fittings and service pipes should be replaced at the same time as the water main renewal. It is recommended that all service pipes and fittings be renewed when water mains are replaced.

Reliability / Availability Failures recorded in the last years do not indicate any particular pattern although a significant number of failures occur in customer service lines. The soil condition is generally decomposed granite typical of the area.

The Charters Towers network is subject to base level water restrictions with one sprinkler free day.

Maintainability Generally the system is relatively easy to maintain.

Storage Storage facilities are in a reasonable condition.

Reticulation The reticulation system is small and readily maintained.

Service Fittings The fire hydrants are of uncertain quality.

5.3 ASSET PERFORMANCE

Water Quality The main issue in relation to water quality is the high levels of silt found at high flows in the Burndekin. This causes problems for treatment.

Water Capacity The river flow is sufficient for the town needs although conservation and restrictions will apply during extended periods of dry weather.

Economic Efficiency The system is too small to expect any major efficiency gains.

Reliability / Availability Reliability is dependant on the power supply which can drop out unexpected due to unforeseen causes. When this occurs the units need to be reset.

Maintainability There is no difficulty with maintainability of the system

Storage Storage facilities are relatively new and owned by Carpentaria Gold.

Reticulation The reticulation system is new, and for the small population is readily maintained.

Service Fittings Service fittings are new with the pipe network system.

6.3 ASSET PERFORMANCE

Water Quality There main issue in relation to water quality is the filtration during high flow periods in the river when there is high silt content.

Water Capacity The town uses only a small percentage of the water provided to the mine.

Economic Efficiency The system is too small to expect any efficiency gains.

Reliability / Availability Reliability is dependant on the flow in the Burdekin River and the allowable take during periods of low flow.

Maintainability There is no difficulty with maintainability of the system as the system is very small and new.

7.3 ASSET PERFORMANCE

Water Quality There main issue in relation to water quality is the chemical composition of the bore water which can sometimes be variable.

Water Capacity The bore is sufficient for the town needs.

Economic Efficiency The system is too small to expect any major efficiency gains.

Reliability / Availability Reliability is dependant on the power supply which can drop out unexpected due to unforeseen causes. When this occurs the units need to be reset.

Treatment Plant The treatment plant is in good condition.

Storage The storage is in detention ponds assists with final effluent treatment before discharge.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix B Version 1 – November 2009 Page 21 Reticulation

The reticulation is in fair condition and will require replacement in the future. Continuing maintenance should be able to hold the reticulation network performance.

8.3 ASSET PERFORMANCE

Effluent Quality The effluent quality meets the EPA licence requirements. The Irrigation effluent achieves Class B for irrigation. Test results generally meet the median values.

Table 8.4 Effluent Quality Limits

Quality Characteristics Release Limit Monitoring Frequency 5- Day Biological Oxygen Demand <45 mg/L Monthly Suspended Solids <60 mg/L Monthly pH 6.5 – 8.5 Daily Dissolved Oxygen > 2 mg/L Daily Free Residual Chlorine <0.7 mg/L Daily Faecal Coliforms Average 1000 /100mL Monthly

Plant Capacity The treatment plant is capable of treating waste water from a population of 10,500 including sewage from industry and other trade wastes.

Economic Efficiency The major cost is the pumping of the effluent to the treatment plant. The topography means that a pumped system cannot be avoided. It is not efficient during wet weather when there is excessive inflow and infiltration into the drainage network.

Reliability / Availability The pumping system is redundant (N+1) which makes the pumping and treatment reliable, however the system is power dependant and emergency generators are necessary to avoid significant discharges of untreated effluent.

Maintainability Pipe failures in the reticulation system while easy to repair are a constant problem. The vitreous pipes should be replaced first as part of a replacement programme. More robust uPVC pipes should be considered.

Section 70 of the Water Supply (Safety and Reliability) Act 2008 requires regulators to have an approved Strategic Asset Management Plan to ensure the continuity of services.

The original guidelines for the preparation of a SAMP allowed for the Council to submit the TMP as a dual purpose document, however experience to date has indicated that Council should also contain summary data in a stand alone SAMP, for ease of reference by the regulator.

This appendix identifies the parts of the CTRC TMP that correlate to the SAMP. A copy of the Approved SAMP is also included in this Appendix.

2 REGISTERED SERVICES The Registered Services and summaries are included in Appendix B.

2.1 Nature and Extent of services

In this plan, some population figures for the communities served have been taken from data supplied by CTRC and are identical to data used in other water asset management documents. While on the surface there are differences in population figures between this information and the data found from the Australian Bureau of Statistics, it is unlikely that the boundaries of the water service area and the statistical areas are different. Assumptions drawn from water meter records are still to be confirmed from other Council records and shall be completed when the TMP for Water and Sewer is prepared.

Charters Towers’ water supply serves a population of approximately 9400. It includes the service area of Charters Towers City Council and the surrounding edges of the city previously in Dalrymple Shire. Water is sourced from weir storage on the Burdekin River (The Burdekin Weir) and is treated prior to storage in two main reservoirs. Water is reticulated throughout the city from the reservoir storage. This network is maintained in good condition and has been calculated at being 25 years.

Greenvale water supply is sourced from the Burdekin River from 3 deep vertical wells. Water is pumped to storage with chlorine injection for disinfection and minimal treatment. Water is reticulated to the township through a network believed to be around 40 years. Ravenswood water supply is originally sourced from the Burdekin River by Carpentaria Gold. Water is pumped to a “turkey nest” dam before Carpentaria Gold provides water to the township. The assumed age of this network is 7 years and is owned and maintained Charters Towers Regional. Pentland Water supply is sourced from ground water in the Haughton bore field. Two bores pump water to a small treatment plant where water is disinfected before reticulation to the township. The average age of the network is assumed to be around 50 years. As this scheme is a groundwater recharge system it is included in the document for completeness but no additional investigation is required unless conditions change. The Charters Towers Sewage Treatment Plant was commissioned in 1976. The system consists of a piped reticulation network and trunk mains. The final effluent delivery to the treatment plant is through a 450mm diameter gravity main to the grit trap and screen at top of the plant.

3 SERVICE SYSTEMS OVERVIEW

The Service Systems Overview is included in Appendix B.

3.1 Infrastructure Overview

The Water and Sewerage Infrastructure details documented in appendix B are listed in the Council’s existing asset registers. Infrastructure assets from all water supply and sewerage schemes operated by Charters Towers Regional Council have been identified in this section. The current cost, current value and annual depreciation of water and sewerage infrastructure assets are based on the information present in the Excel asset registers. The asset register is reviewed and updated regularly. Revaluation of water and sewerage assets is planned in 2009. The water and sewerage asset values presented in this document are based on the 2006

4 LEVELS OF SERVICE CUSTOMER SERVICE STANDARDS The Levels of Service Customer Service Standards is included in Appendix R. The customer service standard that we have developed primarily focus on the following key performance areas:

• Day‐to‐day Continuity of Water Supply; • Adequacy and Quality of the Water Supply System; • Effective Transportation of Sewerage Effluent; • Long term continuity of Water Supply Services; • Long term continuity of Wastewater Services

The performance Indicators and targets prepared and adopted by Charters Towers Regional Council for each of the above areas are summarised in Appendix. These levels of service have been set through:

• Historical performance data; • Design data; and • Consultation with the document “The Performance Monitoring Report for Australian Non Major Urban Water Utilities”.

The customer service standards we have developed are tailored to meet the current expectations of a small to medium sized community system. These differ from those in a large urban community where the impact of loss of service is

Reference: A13004 SAMP Page 6 of 20 considerably greater and invariable reported more quickly. While it is recognised that systems will need to be improved or enhanced to meet customers’ growing expectations over time, customers in the Charters Towers Regional community generally recognise that the existing system is sufficient to meet their needs most of the time. The “Actual” levels of service provided will be monitored through information recorded in the following forms and reported monthly.

• Service requests/complaints /Action request form • Planned Service Interruption Record –Water Supply • Summary Physical/Chemical Water Quality ;and • Summary Microbiological Quality A review of the effects of operation, maintenance and renewal activities identified in this SAMP is an integral part of management, to complete the management loop. The performance indicators (PI) we have adopted are easily measurable and the targets we have set for each PI are based on evaluation of the conditions of water supply and sewerage assets. The main objective of reviewing standards of service is to determine to what degree the target levels of service are being achieved. Standard of service will be reviewed annually with assistance from the following:

• Community satisfaction, measured by numbers of and nature of complaints received and results of annual customer survey; • Examination of movements of key performance indicators; • Changes in asset condition; and • Valuation of water and sewerage infrastructure assets. •

5 OPERATION AND MAINTENANCE RENEWALS STRATEGY

Generally the Operation and Maintenance Renewals Strategy is included in Appendices E, P & F of the TMP and this document. Appendix E covers matters relating to the Operations and Maintenance and along with references to detailed operations and maintenance procedures held by the Manager Water Supply. Appendix P covers environmental management issues as they relate to the operation of water supply and sewerage systems,

Appendix F contains the overall financial arrangements for the

Reference: A13004 SAMP Page 7 of 20 5.1 System Monitoring and Control

Charters Towers Water Supply Scheme

The water supply at Charters Towers is monitored by a Rad‐Tel SCADA system. The SCADA system controls treatment plant operation and monitors levels in the reservoirs. Alarm signals are transmitted to the depot and manager’s pager. Alarms include power failure, low and high water levels in the reservoir and out of tolerance treatment plant outputs, pump failure and no start after power failure.

Charters Towers Waste Water Treatment Plant The water supply at Charters Towers is monitored by a Rad‐Tel SCADA system. The SCADA system controls treatment plant operation and monitors levels in the reservoirs. Alarm signals are transmitted to the depot and manager’s pager.

Pentland Water Supply Scheme

The water supply at Pentland is monitored by a local telemetry system on the groundwater bores and. A town resident has been charged with the monitoring duties, contacting the staff in Charters Towers for operation and maintenance issues as they arise.

Greenvale Water Supply Scheme

Greenvale has a small treatment plant and SCADA monitoring of performance includes alarms similar to the Charters Towers System

Ravenswood Water Supply Scheme

Carpentaria Gold supplies water to Ravenswood. Charters Towers Regional Council only controls a small (relatively new) pipe network

1 INTRODUCTION

To be able to effectively manage public sector infrastructure assets, systems are required that record:

• Physical details or attributes of the assets. • Current physical condition and performance of the assets. • Likely failure mode or decay curve of the asset and hence have the ability to predict the rate of progress along this decay curve by condition monitoring/ranking or other method. • Ability to determine a minimum level of service to which the asset should be allowed to decay. • Various renewal (treatment) options that could be used and their effect on the performance of the asset thereby enabling a renewal decision to be made for the most cost effective option. • Ability to rank these asset renewal programmes together with new works projects and other opportunities for investment on a true cost benefit or consequence of failure (risk management) ranking system.

The assumptions for asset valuation include:

• Base life. • Level of utilisation on the economic life. • Current condition. • Current performance capability. • Effect of the asset’s condition on the life. • Effect of the asset’s performance capability on the economic life. • Effect of externalities i.e. issues not directly associated with the assets themselves but which will none the less affect the timing of asset renewal/replacement.

2 ASSET VALUATION

Water infrastructure assets have been valued at replacement cost written down to reflect the estimated residual life calculated on a straight line basis over their remaining useful lives. The current values excluding land are shown in Table D-1. These values have been provided by CTRC as estimates for the combined council in June 2009. Asset Valuation will be required to confirm these figures.

The approach to recognising changes in service potential is as follows:

• Decline in service potential is expensed each year on a straight-line basis. • Any work undertaken to reinstate the service potential is capitalised. • In addition any work undertaken which adds to the service potential of the asset is also capitalised.

1 BACKGROUND

Asset operational activity is work or expenditure which has no effect on asset condition but which is necessary to keep the asset functioning. For example, the provision of energy, staff, consumable materials and resources. Asset operational activities exclude maintenance work.

Manuals on operational requirements, procedures and activities have been documented and recorded. The majority of the processes and renewals decision-making are based on local knowledge and judgement of a few experienced, long serving staff. This remains to be the case even though records are becoming sufficient to base activities on the failure records rather than relying on experienced staff. Therefore staff turnover rate is a problem for Charters Towers Regional Council.

Systems are being installed to ensure that institutional knowledge is recorded.

2 OPERATIONAL PHILOSOPHY AND STRATEGIES

Water supply and sewerage assets strategies are translated into detailed work programmes and budget projections for each water supply scheme in order to provide the agreed levels of service while optimising lifecycle costs.

The operational strategies are:

• Prepare quality activity plans based on a sound knowledge of customer needs and preferences. • Optimise asset management practices and decision-making by: - Implementing a recording strategy as part of an asset management system - Documenting existing, and developing new business processes - Collecting activity data – physical attributes, asset performance/ condition and costs - Monitoring flows at key locations to provide records of water usage in accordance with the SLMP (Appendix N) and to monitor inflow and infiltration in the sewerage network. • Determine the condition and decay rates of materials by analysing condition reports provided during the day-to-day operation of water supply assets and, as necessary, carrying out material testing.

Operate urban water supply assets in accordance with current NHMRC Guidelines by:

• Carrying out a potable water testing programme to monitor compliance with water standards and customer service standards. This includes monthly monitoring of source water, as well as ensuring procedures are also in place for response to fail results. • Providing appropriate supervision for treatment plants and pump stations.

Improve water supply within the desired level of service over 5 years by:

• Monitoring the frequency of water quality testing.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix E Version 1 - December 2008 Page 1 • Installing telemetry to monitor asset status and performance where applicable.

Minimise asset ownership costs by:

• Considering all life cycle costs, including operational costs, when evaluating asset renewal/development options. • Conducting energy audits to identify any changes that would achieve energy savings. • Identifying, evaluating and introducing new technologies and monitoring/control equipment that may improve operational and management efficiency and modify standards as appropriate. • Continue to observe competitive tendering procedures for asset construction works. • Monitor water usage and, as necessary, undertake leak detection studies to identify the sources of leakage from the system - refer SLMP (Appendix N).

Manage risk exposure by:

• Maintaining current fault detection systems and provide a prompt and effective response procedures to system failures and pollution incidents. • Contamination of water supplies from backflow has been identified as a high risk, particularly from farmers.

The following improvement activities were identified:

• Maintaining appropriate insurance cover for key assets. • Undertaking structural checks of key assets. • Include succession planning and information/skill sharing processes to manage loss of key staff/institutional knowledge.

3 MAINTENANCE STANDARDS AND SPECIFICATIONS

All materials used in the maintenance and repair of the water supply system will comply with all relevant technical standards.

All maintenance work undertaken will be in accordance with:

• CTRC contract documents. • Good plumbing practice. • Approved safety plans. • Safety Guidelines for working on the road. • ‘Classification of Hazardous Areas’. • Electrical Regulations.

Charters Towers Regional Council Appendix E Total Management Plan for Water & Sewerage Services Page 2 Version 1 - December 2008 4 OPERATIONAL AND MAINTENANCE WORK ACTIVITIES AND BUDGETS

The following tables and figures detail anticipated operational and maintenance work needs and costs over the next 10 years for:

• Operational activity (monitoring, inspections, testing, meter reading, etc). • The nature and cost of unplanned maintenance undertaken. • Expected preventative maintenance work requirements.

1 INTRODUCTION

Urban water supplies will be developed to meet community expectations, growth projections over the next 10 years, and technical and environmental standards.

Figure F-1 shows a summary of the CTRC’s financial projections for water supply and wastewater development. Generally the current projections are for static demand, although the vision for Chaters Towers City over the next 20 years is allowing for a static growth.

Figure F-1: Charters Towers Regional Council’s Financial Projections for Water Supply and Wastewater Development – 10 year

2 CHARTERS TOWERS DEVELOPMENT PROGRAMME

A number of upgrading works have been planned for the next few years. These are:

• Possibilities of upgrading water treatment plant.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix F Version 1 - December 2008 Page 1 • Possibilities of extending sewerage reticulation network (depending on development). • Renewal of Sewer Mains – This is the significant programme for the Chaters Tower system and is being carried out to address the significant inflow and infiltration which is occurring in the system due to pipe failure. The programme involves renewal of the sewer reticulation over a three year period.

Date Estimated Capital Cost Description

2009 - 2010 $2,000,000 Upgrade of 2009 - 2013 $500,000 Possible ext 2018 Begin sewerage main renewals

3 PROCUREMENT AND MANAGEMENT OF NEW CAPITAL WORKS

3.1 STANDARDS AND SPECIFICATIONS

The standards and specifications for new works are generally in accordance with all relevant Australian Standards and State guidelines.

For the sewer network polyethylene (PE) and polyvinyl chloride (PCV) uPVC pipes will be used where possible because the installation cost is less than alternatives and because it has flexible and robust joints, is not susceptible to corrosion, root invasion and it has superior flow characteristics. In the case of the water supply system PE pipe will be used and where the allowable pressure for PE is exceeded, steel pipe suitably protected against corrosion will be used. The ground environment is noted as “harsh” and of particular note is the daily vibration from underground mine activities.

3.2 PROJECT MANAGEMENT AND ASSET HANDOVER

The majority of capital works are carried out in-house by Council staff in accordance with the Council’s Quality Assurance Manual and Operational Procedures.

Where works are carried out by external contractors, the contract documents will clearly document and specify the project management processes and asset handover procedures. These will be developed on an as required basis to suit the specific project being undertaken, but will generally be in accordance with state and industry best practice.

1 DEVELOPMENT CONTRIBUTIONS / FINANCIAL CONTRIBUTIONS

Charters Towers Township is developing in the rural fringe (lifestyle blocks) as well as infill within the city; generally the land is being developed without extending services. It is expected that in time the Council will need to extend services further into the city fringe and as a result a specific development contributions policy is considered necessary.

Provision of water supply reticulated services within any new sub-division developments will be the responsibility of the developer and will be constructed to current council standards. It is expected that for the foreseeable future CTRC will work with developers to ensure that appropriate waters supply pipeline networks are installed. Wastewater will be treated using approved “on-site” treatment and disposal methods.

1 INTRODUCTION

A very important aspect of the water supplies function is to ensure that CTRC’s natural water sources are managed responsibly.

Water permits are required for the abstraction of all natural water that is used for public supplies. These usually stipulate the quantity of the water allowed to be taken and a maximum rate for its abstraction. When water and waste water is treated, permits are also required for the discharge of the backwash water and other treated effluents.

The Water Act 2000 and the subsequent Water Supply (Safety and reliability) Act 2008 requires Council to manage the use, development and protection of water resources so that it can meet the reasonable foreseeable needs of future generations. The Council is conscious of its responsibility to the community within the constraints of the Queensland rural environment.

In managing the use, development, and protection of natural and physical resources Council must:

• Recognise the relationship of aboriginal and their culture and traditions with their ancestral lands, water, sites, and other items of cultural significance. • Comply with the Council’s Planning Scheme • Comply with development permits issued by the Department of Natural Resources for water takes and discharges.

2 CURRENT DEVELOPMENT APPROVALS / WATER LICENCES

Table H-1 lists the water supply activity permits and EPA Licences that are presently held. The extent to which council has been able to meet all the conditions of each permit is reported in its Annual Report each year (Refer Appendix X).

1 INTRODUCTION

Mid to long-term renewals expenditure forecasts are assessed with reference to network component age information, assessed base lives and resultant calculated remaining lives. In general, the life cycle expectations for water supply and wastewater assets are:

• Structures - 50 - 100 years • Pipes - 30 - 80 years (steel) • Mechanical equipment - 10 - 40 years • Electrical equipment - 10 - 15 years

2 PRIORITY RANKING

Short-term forecasts and annual programmes are determined with reference to the mid to long-term information, augmented with condition information (where available), maintenance history and failure records, and the priority ranking table (Table I-1) below.

Table I-1: Selection Criteria for Asset Renewal

Priority Renewal Criteria

1 (Low) . Existing asset materials or types are such that known problems will develop in time. 2 . Existing assets h ave a low level of flexibility and efficiency compared with replacement alternative. 3 . Reticulation maintenance involving two to three visits annually. . Difficult to repair, due to fragile nature of material, or obsolescence. 4 . Failure of non-critical asset is imminent and renewal is the most efficient life cycle cost alternative. . Maintenance requiring more than six visits per year. . Fault causes repeated complaints in excess of one per month. . Road upgrading scheduled for the current or following financial year. 5 (High) . Asset failure has occurred. . Asset failure of critical system component is imminent. . Regular maintenance required - more than 3 repairs/ year or 2 visits per month. . Fault has, or is liable to cause flooding to houses or shops. . Complaints of re-leaks, water starvation and dirty water resulting in a significant health risk.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix I Version 1 - December 2008 Page 1 3 RENEWAL STANDARDS AND SPECIFICATIONS

The standards and specifications for renewal works are generally the same as for development works. They will be updated regularly to incorporate relevant experiences and changes in best practices.

In general, unlined steel pipe and asbestos cement pipes in the case of the water supply system and vitreous clay pipe in the case of sewer are most likely to be failing or expected to fail in the next 10 years. The asbestos cement pipe used for a large part of the water supply mains is not showing signs of ageing at this time, which could be attributed to the age of the pipe and the good construction techniques in the 1960’s.

Pipe sections are generally assessed to be at the end of their useful life when there is sufficient failure record within the environment and pipe type to indicated general failure of the network or parts of the network.

The asbestos cement pipe is expected to be replaced using a combination of High Density Polyethylene (PE) pipe, Denso wrapped steel pipe, Polyvinyl chloride (PVC) coated steel pipe, and PVC Hi-strength schedule 80 pipe and uPVC pipe.

For the sewer network uPVC and PE pipes will be used where possible. The installation cost is less than alternatives and these pipe types have flexible and robust joints. The pipes are generally not susceptible to corrosion, root invasion and have superior flow characteristics.

4 10 YEAR RENEWAL PROGRAMME

The Renewal Programme for water and sewer services is summarised in Figure I-1 below and provided in more detail in the following sections.

Figure I-1: 10 Year Renewal Plan Water and Sewerage

Charters Towers Regional Council Appendix I Total Management Plan for Water & Sewerage Services Page 2 Version 1 - December 2008 4.1 CHARTERS TOWERS RENEWAL PROGRAMME

The major renewals that are included in the 10-year projections are:

• Renewal of hydrants & valves - Hydrants and valves typically has base lives half that of the water mains they are connected to. The Council policy is to replace hydrants and valves when they fail or when the water mains they are connected to are renewed. • Possible replacement steel rising main and replacement of reservoir number 1 depending on asset condition. • Renewal of asbestos cement pipes at the end of the 10 year period.

Table I-2 shows the financial projections for renewal works over the 10-year planning period.

1 INTRODUCTION

Determining an accurate figure for infrastructure consumption is a complex matter. The long lives and unique nature of many of our passive infrastructure assets are dramatically different to the “short lived” commercial assets operating in a competitive environment where accrual accounting or current cost techniques have their basis. In applying depreciation principles to infrastructure assets it is important that we recognise the critical differences: • If we use straight-line depreciation it will reflect a far greater consumption or depreciation figure than is actually required in the initial stages of asset life. • Most passive assets have a variety of failure modes other than just their effective life e.g., technological change / capacity. • Most passive assets do not have to be returned to an “as new” value but can operate at a lower (acceptable) level of service for that type of asset, providing that they deliver the performance and reliability (or other standard) that is determined acceptable by the customers (or rate payers).

The critical issue is not asset consumption but predicting the cash flows required by our asset stocks to maintain an acceptable level of service and to provide new services as required by our customers. The valuation process places great reliance on the figures used for the depreciated replacement cost for each asset.

The Council has little real information on the useful life of most of its assets, due to the short duration of asset management records, and a small sample size within major networks. Specifically, Charters Towers is relatively small, and the number, types and locations of failures are showing no particular statistical pattern. In addition to this, Charters Towers is a young network and all of the infrastructural assets have not yet reached the statistical base life.

The lack of detailed historical knowledge on asset durability and performance has meant that the calculation process used to predict the cyclic renewal of utilities assets and the decline in service potential of the existing assets is based on a number of assumptions. The assumptions for each asset include:

• Base life • Level of utilisation on the economic life • Current condition • Current performance capability • Effect of the asset’s condition on the life • Effect of the asset’s performance capability on the economic life • Effect of externalities i.e., issues not directly associated with the assets themselves but which will none the less affect the timing of asset renewal / replacement.

While best practice and current knowledge has been used in making and applying these assumptions this knowledge and practice is not supported by solid historical data. The longevity of the assets concerned and the relative youth of the majority of the assets means that nationally the local government industry has yet to go through one full asset life cycle. The net result is that, due to the number of unsupported assumptions made in the preparation of this plan, and the impact each of the above assumptions has on the predicted level of decline in service potential, there is limited confidence in the resultant depreciation figures.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix J Version 1 - December 2008 Page 1 In spite of significant assumptions, depreciation recognises the consumption of economic benefits of an existing asset, it is generally accepted that this can provide an indication of funds that will need to be set aside each year to allow replacement of the asset at the end of its life.

In making the decision to fund the depreciation from the CTRC rate payers it is essential to ensure that the level of funding sought is fair, reasonable and sustainable to the community, or section of the community which has to pay.

The asset management plans for the Council’s assets will be progressively updated as more complete information becomes available over time. A programme to update information is in place and data is continually being improved.

Regardless of the above uncertainty the requirements of the Local Government Financial Standard demands that straight-line depreciation be used for calculation. The approach to recognising changes in service potential is as follows:

• Decline in service potential is expensed each year on a straight-line basis. • Any work undertaken to reinstate the service potential is capitalised. • In addition any work undertaken which adds to the service potential of the asset is also capitalised.

2 DATA REQUIREMENTS

To be able to effectively manage public sector infrastructure assets, systems are required that record the:

• Physical details or attributes of the assets. • Current physical condition and performance of the assets. • Likely failure mode or decay curve of the asset and hence have the ability to predict the rate of progress along this decay curve by condition monitoring / ranking or other method. • Ability to determine a minimum level of service to which the asset should be allowed to decay. • Various renewal (treatment) options that could be used and their effect on the performance of the asset, thereby enabling a renewal decision to be made for the most cost effective option. • Ability to rank these asset renewal programmes together with new works projects and other opportunities for investment on a true cost benefit or consequence of failure (risk management) ranking system.

3 WATER SUPPLY SYSTEMS ASSET DEPRECIATION

In general, the life cycle expectations for water supply assets are:

• Structures - 50 - 100 years • Pipes - 30 (steel) - 80 years • Mechanical equipment - 10 - 40 years • Electrical equipment - 10 - 15 years

Charters Towers Regional Council Appendix J Total Management Plan for Water & Sewerage Services Page 2 Version 1 - December 2008 4 RELATIONSHIP BETWEEN RENEWALS NEEDS AND THE ABILITY OF DEPRECIATION TO FUND

Capital expenditure on renewals or replacements of existing assets will be funded from accumulated depreciation funding. Water supply infrastructure assets have been valued at replacement cost written down to reflect the estimated residual life calculated on a straight line basis over their remaining useful lives.

Table J-1 shows the asset valuation and annual calculated Decline in Service Potential (DISP). DISP recognises the consumption of economic benefits of an existing asset, and indicates the funds that will need to be set aside each year to allow replacement of the asset at the end of its life.

2 REVENUE AND FUNDING

For all Charters Towers City water and sewerage projections income revenue is funded by way of rates and user charges. Generally the Council budget allows for funding of minor capital works from the general account. Special capital projects are funded from grants with the assistance of loan funding if required.

3 FINANCIAL MODELLING

Financial modelling spreadsheets provided by DNR for reporting purposes are attached at Attachement 1. Financial modelling from the spreadsheet should be updated annually as projections for the 10 year program are subject to change.

4 MONITORING AND REPORTING OF FINANCIAL REQUIREMENTS

Financial management is reported to Charters Towers Regional Council on a quarterly basis. A report against the DNR financial model is required every three years, when the TMP is updated or at earlier times if revaluation of assets is completed.

1 FUTURE TRENDS

1.1 POPULATION GROWTH

There has been a general declining trend of the Charters Towers population over the last 5 years although population is more likely to remain more or less static.

1.2 DEMAND FORECASTS

The Charter Towers City will remain a primary industry based economy, with growth dependent on economic conditions and export opportunities for the cattle and mining industry. It is unlikely that the city will grow significantly in the next five years, with a more stable trend likely.

The Council has developed network efficiency and conservation plans for the two water supply systems, and it will use all reasonable and practicable measures to maintain and enhance the efficiency of the water treatment, reservoir, and reticulation components to minimise losses and to manage customer demand.

2 SERVICE DELIVERY TRENDS

The following trends are expected to impact on the quantity and quality of utility services provided:

• Demand for more system control and monitoring to measure and control leakage and losses. • Increasingly stringent water quality guidelines. Charters Towers has a good monitoring regime. • Increased monitoring of water usage per head of population to provide measures of sustainability of the water resource.

3 DEMAND MANAGEMENT STRATEGIES

CTRC has been a member of the Waterwise Program and continues to conduct education programs for the community on the efficient use of water. Council will maintain a strong demand management strategy to ensure the effective and efficient use of the water resource.

The demand management strategies used by Council are as follows:

• Water restrictions and shutdowns: Water restrictions and shutdowns will be used only as a reactive temporary measure to control demand in response to serious system malfunctions, unforeseen circumstances that threaten the town supply, or during periods of excessive demand.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix N Version 1 - December 2008 Page 1 • Public conservation: Water conservation education will be undertaken through publicity and information dissemination. Council will support sensible water conservation by providing encouragement to use water saving devices when dealing with building consent applications and by making available pamphlets and advice on simple water conservation techniques. Charters Towers continues to enforce odd and even watering days and water restrictions during low weir levels in the dry months.

• Water metering: Water pricing via metering or fixed volume restricted supplies will continue to be a requirement. Meters are installed on all connections. The pricing policy is set via Council’s Fees and Charges policy and this is reviewed annually by Council.

• Leak control: Leaks are often noticed and reported within a short time of occurring. The Council is in the process of modelling the reticulation networks and investigating non-revenue water usage for the small communities.

• Private supplies: The construction of private domestic water supplies (other than outside of the water supply area) is not encouraged for Charters Towers. There is insufficient regular rainfall in the region to maintain rainwater tanks with fresh water and there are health concerns with mosquitos and untreated water from alternative sources being used for drinking purposes. The Council therefore considers that the provision of a complete water supply service to the community, where this is possible, as the most efficient approach to ensuring the health and safety of the community.

• Effluent Reuse: Effluent reuse reduces Council’s fresh water use for irrigation. Council is considering the expansion of the waste water effluent reuse area.

4 LEAK MANAGEMENT

4.1 PROMOTE THE EFFICIENT USE OF WATER

Council will promote the efficient use of water by: • Encouraging and promoting a voluntary water conservation program in Charters Towers. • Setting water pricing structures which balance the need for affordable water for the community and encouraging efficient use of water • Continuing to demonstrate efficient use of water in Council activities by effluent reuse for irrigation purposes where possible. • Regular review of measures and achievements and annual reporting against these achievements as set out in Appendix R.

4.2 MINIMISE LOSSES

Council will take steps to minimise losses in the system by: • Conducting an annual water balance / audit reconciling water abstracted from the delivery meter against water consumed (measured by water meters on individual connections) to assess the level of leakage in the network.

Charters Towers Regional Council Appendix N Total Management Plan for Water & Sewerage Services Page 2 Version 1 - December 2008 • Developing District Metered Areas (DDMA) for better analysis of pipe flows and leakage analysis (DDMA will follow the existing water areas). • Quality control of pipes, fittings, construction procedures for all new works and repair works. • Mains replacement and rehabilitation programmes. • Analysis of leak location and identification of problem areas. • Regular inspection, maintenance and servicing. • Continual update of accurate service records. • Leak detection programme. • Quick response to reports of leaks and rapid rectification of faults. • Clear message path for calls received from public. • Pressure management

4.3 CONTINUOUS MONITORING

Continuous monitoring of the supply end at the reservoirs via a telemetry system would provide early warning of problems and allow for a rapid response for repairs and maintenance.

4.4 PREVENTATIVE MAINTENANCE

Regular preventative maintenance of valves and hydrants should continue to maintain efficiency.

4.5 ILLEGAL CONNECTIONS

Illegal connections are not considered to be a major issue at this time. However, field studies are still required to investigate losses in the water supply system. There is no indication of cross connection to the storm water or sewer system.

4.6 FIELD MEASUREMENTS

Field measurements are carried out as follows:

• Flow meters installed at key points at the reservoirs to which data loggers may be connected. • Telemetry monitoring of flow meters at DMA. • Data loggers which can record both pressure and flow at the metering point.

NOTE: The TMP Overview indicates that Charters Towers has a small amount of systems leakage at 67litres per connection per day indicating “good” performance of the system. The losses in small communities require further monitoring and analysis.

PREAMBLE

This System Leakage Management plan is the initial analysis and plan for the Charters Towers Regional Council. Charters Towers City Council and Dalrymple Shire Council both required System Leakage Management Plans to be prepared in accordance with Chapter 3 of the Water Act 2000. Charters Towers had a Demand Management and Water Loss Plan as part of its Total Management Plan. The Charters Towers TMP was produced in 2001 and requires updating. This document covers the water supply area of the amalgamated council.

The System Leakage Management Plan is written so that it can be included into a new Total Management Plan for Water and Sewer Services which will combine the assets of both councils into one management plan and is expected to be prepared later in the year.

Charters Towers City and the regional area are located on an eastern plateau and slopes of the Great Dividing Range in tropical . The Council area boundary to the west is on a ridge of the Burra Range. As such, the area receives regular tropical monsoon rainfall. The Burdekin River is located in a major catchment and is the water source for three of the communities in the .

The town of Pentland uses a ground water source, which has sufficient yield adequate for the population of the town.

System Leakage Management Plan Revision November 2009

Page 2 Charters Towers Regional Council

1. INTRODUCTION

The System Leakage Management Plan (SLMP) for Charters Towers Regional Council provides an initial estimate of leakage and a program of leak reduction and investigation. It is clear from the data available that initial action should be taken to improve and monitor the data collection of the amalgamated council. This SLMP should then be updated as more data is available and as improvements are made to the water supply system.

Because the main area has had a System Leakage Plan in place for a number of years, the initial findings of this investigation as part of the SLMP plan indicate that it is unlikely that there will be significant savings resulting from water loss reduction. Current reactive maintenance is maintaining the network in an adequate condition and un-accounted for water figures are relatively small.

The management plan is developed to be part of the overall management of water and wastewater assets for Charters Towers Region, while meeting the legislated requirements for the production of the management plan for system leakage. A Total Management Plan for water and sewer is expected to be produced prior to the end of 2008. This will combine the assets of the Charters Towers City and the Dalrymple Shire assets as part of the new Charters Towers Regional Council local authority area.

Some of the information and data is this plan (particularly the parts relating to descriptions of the asset) will eventually be referenced from other plans in the suite of documents that make up the Total Management Plan (TMP) for water and sewerage services. As a result the information is only provided in summary form in this document.

The analysis of the data has been carried out based on information and templates from the Queensland Water Directorate, and methodology from the International Water Association Specialised Taskforce on Water Loss. The results are therefore a combination of the thinking of the QWD and current international best practice. The two are not mutually exclusive.

2. LEGISLATION

The amendments to the Water Act 2000 require that all registered service providers prepare a SLMP.

Chapter 3 s414 A & B of the Act requires that service providers other than those only supplying drainage or sewerage scheme has SLMPs in place to minimise the water losses due to leakage from their water supply distribution systems. The plan is required to document the actual level of leakage, indicate measures to reduce leakage and set out a plan to implement those measures.

For Charters Towers Regional Council the SLMP was due on 1 October 2007. Staff and consultant shortages in North Queensland made this target unachievable, although this document will be submitted in April 2008 to meet the legislative requirements.

3. DESCRIPTION OF SCHEMES

There remains a significant work to combine the schemes for the towns into a single format with readily accessible data. Asset data is available but has not been collated at the time of writing because of the difficulties of extracting the data from the Asset Databases. Tables 3-3 to 3-5 will be updated as the information on assets is collated and confirmed as part of the development of a Total Management Plan covering the new amalgamated council area. For the purposes of this document the lack of data is not significant and it is considered better to leave blank spaces rather than include data which may be proven inaccurate. The schemes have been described from data made available to Good Earth Matters Consulting by Council staff.

In this plan the population figures for the communities served have also been taken from data supplied by Charters Towers Regional Council and are the same as data used in other water asset management documents. While, on the surface there are differences in population between this information and the data found from the Australian Bureau of Statistics, it is likely that the boundaries of the water service area and the statistical areas are different. The assumptions drawn from the water meter records are still to be confirmed from other Council records. All assumptions will be confirmed when the Total Management Plan for Water and Sewer is prepared.

Charters Towers’ water supply serves a population of approximately 8,900 and includes the service area of Charters Towers City Council and the surrounding edges of the city previously in Dalrymple Shire. Water is sourced from weir storage on the Burdekin River (The Burdekin Weir) and is treated prior to storage in two main reservoirs. Water is reticulated throughout the city from the reservoir storage. As more recent asset data was available the average age of the network has been calculated at 25 years. The network is maintained in good condition.

Greenvale water supply is sourced from the Burdekin River from an “infiltration gallery” fed by spear pumps. Water is pumped to storage with chlorine injection for disinfection and minimal treatment. Water is reticulated to the township. Average age of the network is believed to be around 40 years.

Ravenswood water supply is originally sourced from the Burdekin River by Carpentaria Gold. Water is pumped to a “turkey nest” dam. Carpentaria Gold then supply water to the township of Ravenswood. Charters Towers Regional Council own and maintain the reticulation network. Average age of the network is assumed to be 7 years.

Pentland Water supply is from ground water source in the Haughton bore field. Two bores pump water to a small treatment plant and reservoir where water is disinfected before reticulation to the township. Average age of the network is assumed to be around 50 years. As this scheme is a groundwater recharge system it is included in the document for completeness but no additional investigation is required unless conditions change.

Schematics of each of the 4 water supply schemes are included at Appendix A

Each of the four supply schemes are to be treated as district metered areas for the purposes of leak detection, and economic analysis of leak reduction methods.

4. INTERNATIONAL WATER ASSOCIATION BENCHMARKING WATER LOSS

The Guidelines for the Preparation of a SLMP (The Guidelines) do not recommend some of the International Water Association (IWA) indicators, in particular, the Infrastructure Leakage Index. The reasoning for this is that it may give unreliable results in some systems – this is particularly true for small networks which comprise the majority of networks in Queensland.

Even so, the methodology used for calculating the components of the IWA Water Balance Table is the means for calculating the required indicators for reporting water leakage. The Water Balance Table allows the input water and output water to be categorised and totalled allowing the volume of the losses to be seen. From the table a range of indicators can be calculated.

A range of indicators is important to provide a much clearer picture of network performance, but the indicators need to be understood in the context of the network, environment, ground conditions and community expectations.

Both the IWA and The Guidelines agree that the use of percentage as an indicator is misleading, and therefore percentage is not used as an indicator.

The IWA benchmarking table covers loss in volumetric terms and this is a good indicator of system performance. In the case of the Charters Towers Regional systems, the indicator required by NRM is Volumetric Terms of “Litres per connection per day”.

The Guidelines permit a service provider to calculate the ILI for its own purposes. Charters Towers Regional Council may want to calculate this indicator at a future time when more accurate data is available for Charters Towers City. The Charters Towers city supply system would fall within the category where the ILI could be a valid indicator; however the other small systems would not.

Charters Towers Regional Council may also use the water balance table converted to dollar values as an economic indicator of the costs and benefits of pursuing water leakage.

The IWA benchmarking table is a good indicator of system performance and can be used with both ILI and volumetric loss indicators. The average pressure in the network is important as one of the leakage minimisation strategies involves pressure control.

The Water Balance Table is shown in Figure 4-1.

System Unbilled Un-billed metered consumption input authorised Volume consumption Apparent Metering inaccuracies Non Revenue Water Losses Water (or unbilled volumes) Losses Transmission and distribution mains Real Losses

Figure 4-1: Water Balance Table

While the initial investigation of water losses can be carried out without reference to pressure, the final results may need to be read in conjunction with a pressure distribution of the network.

From the Water Balance Table the following system indicators can be derived:

• Infrastructure Leakage Index (ILI) – indicates system performance in terms of leakage

• Loss per consumer – measured in litres/connection/day (/m head) (pressure may not be included if the system pressure is not known).

The Water Balance Table provides a checklist so that each of the leakage types can be assessed and, if necessary, addressed. Leakage and conservation can be driven from both the consumer and supply side.

While the data available for the study communities is sufficient to estimate ILI and loss per consumer, it is not of sufficient detail to complete the Water Balance Table beyond the first two columns.

4.1 INFRASTRUCTURE LEAKAGE INDEX (ILI)

The infrastructure leakage index (ILI) is defined as:

Infrastructure Leakage Index (ILI) = C A P L MAAPL

System Leakage Management Plan Revision November 2009

Page 10 Charters Towers Regional Council

Where:

CAPL is Current (real) Annual Physical Losses. This is determined from actual system data. The CAPL may also be estimated from system data.

MAAPL is Minimum Achievable Annual Physical losses – the level of losses that one would expect from a utility with a network that is in good condition AND which practises intensive leakage control.

MAAPL is a theoretical level of losses (expressed in L/day) determined from an empirical relationship of system infrastructure data. The formula for MAAPL is as follows: MAAPL = PG (1.8GLM + 0.8GNC + 25GLP) Where:

LM = Length of Mains (km)

NC = Number of Service Connections LP = Length of Service Connections from property boundary to customer meter (Length of pipe on Private land, km). For the purpose of the current study, an average service connection length of 20 m is assumed. P = Average Pressure (metres).

4.2 LOSS PER CONSUMER

Loss per consumer is estimated from system data and expressed in terms of litres per connection per day.

Other useful indicators for apparent loss include:

• Litres/customer/day

• Litres/connection/day/m head.

System Leakage Management Plan Revision November 2009

Page 11 Charters Towers Regional Council

4.3 IWA BENCHMARKING Figure 5-2 shows the IWA benchmarking matrix. This allows a system's actual performance to be assigned as 'A', 'B', 'C' or 'D' grade depending on the leakage indicators detailed above.

Physical (Real) Losses [Litres/connection/day] Technical Performance ILI (when the system is pressurised) at an average pressure of: Category 10 m 20 m 30 m 40 m 50 m

B 2 – 4 50 – 100 75 – 150 100 – 200 125 – 250

C 4 – 8 100 – 200 150 – 300 200 – 400 250 – 500 Countries Developed D > 8 > 200 > 300 > 400 > 500

Figure 4-2: IWA Benchmark Matrix

The category A to D identifies the existing performance and provides notes to guide further loss reduction action. The definitions are as follows:

Category A Good; further loss reduction may be uneconomic; careful analysis needed to identify cost effective improvements.

Category B Potential for marked improvements: consider pressure management, better active leakage control practices, and better maintenance.

Category C Poor: tolerable only if water is plentiful and cheap; even then intensify non-revenue water reduction efforts.

Category D Terrible: inefficient use of resources; non-revenue water reduction programmes imperative and priority.

It should be noted that these categories are a guideline only.

5. INITIAL ESTIMATE OF LEAKAGE

The initial estimate of leakage for Charters Towers City is based on the water balance table format shown in Figure 5-1. The other small supply areas have not been included in this table. Because there is limited data available a simplified table (Figure 5-2) has been prepared for the small communities.

Billed Billed metered consumption (including water

Authorised exported) – 3651 ML/year Revenue Water (or consumption Authorised billed volumes)

Consumption 3751 ML/yr* 3751ML/yr*

System consumption input 50 ML/yr Volume Non Revenue Water Apparent Metering inaccuracies – 39 ML/yr (or unbilled volumes) 3934ML/yr* Losses Water 183ML/yr Losses 41ML/yr

133 ML Transmission and distribution mains - 42ML/yr Real Losses 92 ML/yr

Figure 5-1: Water Balance Table - including data

The results of the initial estimate of leakage for Charters Towers City on first inspection are satisfactory. The main reason for this is that Charters Towers City already has a management programme and data recording in place.

Real losses for Charters Towers are therefore estimated at 67 litres per connection per day. When compared with the IWA Benchmarking Table at Figure 4-2, it indicates that Charters Towers is in technical performance Category A – Good.

Table 5-2 below shows the Water balance information for the small communities. Currently there is insufficient data to analyse the water loss for these small communities. It is estimated that the non revenue water for Greenvale and Pentland could be as high as 50% of the water supplied although the actual leakage figure for real losses is expected to be very small. The recommendation of this plan is to develop better information on the input volumes to the small supplies so that the loss analysis can be completed.

The supply to Ravenswood is a new system and it is unlikely that there are significant losses. The metered volume is low, and it is concluded that better data will indicate that the system losses are minimal.

Pentland Not Known 69141

Figure 5-2 Simplified Table Small Towns

6. INITIAL COST BENEFIT ANALYSIS

Based on the International Benchmarking it is unlikely that a cost benefit analysis will indicate that leakage reduction programme should be carried out.

In order to estimate the possible savings, a level of unavoidable losses needs to be taken from the figure of real losses.

The systems in Greenvale and Ravenswood are considered small systems having less than 1000 connections. For schemes with less than 1000 connections the Guideline cost of a Cost-Benefit Analysis of $20,000 exceeds 10% of the annual Total Water Undertaking Revenue. A detailed SLMP is not required on the basis that the cost of a Cost-Benefit Analysis exceeds the Water Services Provider’s capacity to pay as certified by the CEO. No further investigation is required for these schemes and a Leakage Control System will be undertaken instead.

In addition to this Ravenswood is considered to be a young system of less than 15 years old. Again no specific actions are required under the guidelines.

Assuming unavoidable losses for Charter Towers City are at around 40ML per year the potential savings for the cost benefit analysis are based on 53 ML which includes an allowance for nonrevenue water from the other three small towns.

The cost of a ML of water taken from total operational and maintenance costs of $2.7Million and divided by the input volume of 3934 ML and is found to be $685/ML

The Value of the savings is calculated at $685.00 x 53 = $33,300.00 across the four schemes.

The costs of a leak detection programmes are likely to be between $60,000 and $120,000. It is therefore not economic to pursue further reductions in leaks for Charters Towers as the costs exceed the benefits. The value of the potential savings is low compared to the cost of discovering leaks. It is recommended that only actions which are able to be carried out as part of normal maintenance be undertaken using simple processes and in-house data collection as part of the normal operating and reporting procedures.

System Leakage Management Plan Revision November 2009

Page 14 Charters Towers Regional Council In addition to the analysis above the guidelines also provide for exemptions for medium water supply schemes. Charters Towers scheme has less than 4000 connections which means that it falls within the medium sized scheme category of 1000 and 25,000 service connections. The guideline cost of a Cost- Benefit Analysis of indicated by the Qld Water Directorate ($35,000) exceeds 10% of the annual Total Water Undertaking Revenue. A detailed SLMP is therefore not required on the basis that the cost of a Cost-Benefit Analysis exceeds the Water Services Provider’s capacity to pay as certified by the CEO. No further investigation is required for this scheme and a Leakage Control System will be undertaken instead

7. ASSESSMENT OF POSSIBLE LEAKAGE REDUCTION MEASURES

The following leakage reduction measures for the Charters Towers system are suggested.

Pressure reduction has not been included in the leakage control measures. The pressure is currently at around 45m average which is satisfactory and meets the customer service requirements. Most networks introducing pressure reduction are reducing pressure to around 40m.

8. LEAKAGE REDUCTION PROGRAM

The following leakage control system is proposed for Charters Towers Regional Council water supply areas. The purpose of the program is to do the easy low cost things first, review the data in 12 months and then determine if further leakage reduction actions are economic or required.

8.1 TARGETED METERING AND DATA COLLECTION

The use of targeted metering and better data collection along with the continued monitoring and analysis of the flows will help to better define the actual volume of water being lost to the network. This is the lowest cost option and first step in understanding the leakage in each of the metered areas. Data sets were poor for the small communities, and attention should be given to ensuring that these data sets are complete. Weekly readings for small communities should provide sufficient control to identify leaks or other exceptional flows.

For each of the small communities of Pentland, Ravenswood and Greenvale the actions should be to

System Leakage Management Plan Revision November 2009

Page 16 Charters Towers Regional Council • Ensure that delivery pipelines or reservoirs are metered and read weekly and reported quarterly

• Ensure that services connections are metered and read at least half yearly but preferably on a quarterly basis.

Additional actions as part of the programme may include:

• Major Network flow checks – Moveable meters installed at key points on the network in Charters Towers to check flows. Data log flows over one or two month periods. Also allows for checking of flow and pressure at the different parts of the network.

• Confirm that meters are installed on all parks and reserves irrigation systems – measures unbilled water for community purposes. Read meters at 6 month intervals or at least annually at the end of each financial year.

• Meters installed at all standpipes and record construction water. Read meters monthly. Develop approvals process for use of standpipes.

• Reporting of hydrant use by fire brigade, and Council staff.

• Recording of reported leaks and repairs including time to repair information.

8.2 DISTRICT METERED AREAS

Each of the supply areas will be defined as a District Metered Area. Establish permanent meters in key locations such as reservoir outlets and the inlet pipe to Ravenswood. Read meters on a regular basis, preferably weekly.

Full application of District Metered Areas philosophies is not considered to be economic for Charters Towers. The usual process of automatic recording of data and pressure information would be excessive in an area the size of the Charters Towers Network. It is recommended that a manual recording system as part of daily plant maintenance and inspections will be sufficient to ensure that the data is collected and available.

8.3 NIGHT FLOW MEASUREMENT

Measurement of night and day flows indicates the water use patterns of the community. As data is collected it can be used to identify unusual flows. A significant proportion of unreported leaks can be discovered by using night flow measurement in different parts of the network. This process would only be used if unusual flow are recorded.

8.4 LEAK DETECTION

Leak detection uses expert contractors with electronic listening devices to find leaks by the sound of running water. The technology has become sophisticated over the last few years as there is a move from metal pipes to plastic which does not transmit sound as easily. This method requires specialist and is unlikely to be cost effective.

The Charters Towers Water Supply systems have historically been significantly affected by drought conditions. Charters Towers relies on the flow in the Burdekin River to maintain its water supply. In recent years the height of the weir has been increased to provide greater security of supply. This Appendix O of the TMP for Water and Sewer contains the Drought Management Plan (DMP). The appendix has been written so that the DMP can be reviewed and changed separately.

Other events likely to cause significant service failure have also been considered and these are listed as Table O-1.

Drought Management Plan - Revision June 2015 Page 1

Preamble This Drought Management Plan is a review of the initial Drought Management Plan produced in November 2009 for the Charters Towers Regional Council, which was prepared in accordance with the Water Act 2000 and the Water Supply (Safety and Reliability) Act 2008.

The Drought Management Plan is written so that it can be included in the Total Management Plan for Water and Sewer Services.

The Charters Towers regional water supply systems, reliant on the Burdekin river flow, have been affected by drought conditions and low flow in the Burdekin River. Raising the height of the Burdekin Weir in 1995/1996 has provided sufficient storage to cover the worst historical dry period and is considered to meet the supply needs for the city of Charters Towers. However, the impact of climate change on the river flows is yet to be seen, and therefore strategies to extend the time of available storage to ensure supply during dry periods is required. Pentland has been the exception having a small community reliant on ground water, which tends not to be affected by short term drought conditions.

Charters Towers City and the regional area are located on an eastern plateau of the Great Dividing Range in tropical North Queensland. As such,the area receives regular tropical monsoon rainfall. The Burdekin River is located in a major catchment and is the water source for three of the communities in the Charters Towers region.

The document was originally prepared by Consultants Good Earth Matters Consulting Pty Ltd.

Drought Management Plan - Revision June 2015 Page 2

1. Introduction

In accordance with the Water Act 2000 and Water Supply (Safety and Reliability) Act 2008, Councils were previously required to prepare a Drought Management Plan for each service area in which the service provider supplies water. Councils are no longer required to prepare a Drought Management Plan, however this document provides the basis upon which Council is committed to sustainable water management.

The DMP constitutes Appendix O of the Total Management Plan for Water Supply and Sewerage Services (TMP). It is also intended to stand alone as a separate document for registration. In order to stand alone it includes some system description information which is a summary of more detailed information included in the TMP.

The Charters Towers Regional Drought Management plan covers water supplies to Charters Towers and for the communities at Greenvale, Pentland, and Ravenswood. Communities at Homestead and Balfes Creek are very small and use private water supplies; that is, they are not supplied by the Service Provider (Council).

The Drought Management Plan is intended to cover a reduction in source water such as low flow in rivers, low dam levels or failure of an aquifer which are the results of natural and climatic events. Failures in the water supply network assets (eg: pipe breakage, electrical failure) are covered in the TMP and should be referenced by the Disaster Management Plan for Charters Towers Region.

2. Policy Statement

CTRC is committed to providing a sustainable supply of safe clean drinking water to the residents of Charters Towers, Greenvale, Pentland, and Ravenswood tor the present and future.

CTRC recognises the challenges of the people in living in our remote communities and is committed to encouraging sustainable and wise use of the water resource to ensure that the community can continue to maintain suitable plant growth within the residential parts of the city and rural communities. In doing so, CTRC encourages the selection of appropriate plant species and garden watering patterns.

3. Purpose

The purpose of the DMP is:

• To encourage CTRC customers and the wider community to conserve water and use it wisely;

4.4 Water Sources Assessment

A water sources assessment is provided for each water supply. Information in this section has been collated from the Charters Towers Total Management Plan for Water and Sewerage services, and the Dalrymple Shire Strategic Asset Management Plan, along with river flow and rainfall information readily available. The information in the two management plans has been collated by other consultants and while a quality check of the information has not been completed, the data is consistent with current rainfall and flow patterns in the Burdekin River. While a source assessment from the QWD template has been completed below, there has been little work completed on the water sources since 1995 when the Burdekin Weir was raised 2.2 metres. Since that time the major town has not had critical shortages of water although the flow in the Burdekin does reduce during the dry winter months (refer Section 4.4.5). Additional work will be required as part of the development of a Total Management Plan for Water and Sewer.

A Source Assessment Table from the QWD Template has been completed below.

4.4.1 Greenvale

Water is sourced from the Burdekin River. NRM records for sites in close proximity to Greenvale indicate that the average minimum flow in the last 30 years is approximately 49 ML/day. This figure takes into account some times when there is no flow recorded. Local residents report that there has been not time in the remembered past when the river has not had sufficient flow to meet the community water supply needs at Greenvale, however it is noted that the river has had periods of no flow downstream at the Charters Towers intake point. Because of the small size of Greenvale, water can be readily trucked in for drinking and health purposes.

Drought Management Plan - Revision June 2015 Page 8

Greenvale water has a problem with turbidity at high flows which occur for approximately 3 months of the year This is of greater concern as the cost of developing a treatment plant to filter out the turbidity is significantly more than the community can afford. Treatment options are being investigated by CTRC to ensure suitable water during periods of high turbidity.

4.4.2 Charters Towers

The City draws its water supply from a weir on the Burdekin River approximately 14 km north of the City. The catchment area of the Burdekin to this point is some 34,980 km2, all to the north of Charters Towers. The original weir was constructed in 1902 and was 265 m long and approximately 3.5 m high. The capacity of the weir was 1,950 ML. In 1995/96 the weir was raised 2.2 m with the crest level being RL 231.0 and a total length of 360 m. The capacity of the present weir is 5.227 ML which represents only 0.12% of the average annual flow of the Burdekin River. The weir now provides 7 months secure supply. Calculations on river flow in 1995 indicated that the longest recorded period of no flow at the Burdekin Weir was 7 months and the volume of the weir was calculated for the worst case.

Water restrictions across the Council area will be imposed by CTRC depending on the level of the Burdekin Weir as the trigger point. This should extend the available secure supply for Charters Towers. Because three of the four supply areas will be affected by the flow of the river the use of a single trigger point for the Charters Towers CounciI area is considered to be a pragmatic approach to setting restrictions. Consideration will also be given to the effect of climate change on the river flows.

4.4.3 Ravenswood

Ravenswood supply was installed to connect to the Carpentaria Gold reservoir. The town supply requirements are a small percentage of that required for the gold mining operation. As the original source of the water is the Burdekin River downstream of the Charters Towers intake, the flow is expected to be the same as for Charters Towers, but the community needs are small and restrictions would allow for times of no river flow.

4.4.4 Pentland

Pentland is serviced by a bore field located approximate 10 km from the town. Two bores within the field are used to service the town. The aquifer appears to be permanent for a small community with low total demand.

4.4.5 Past Performance

The water supplies have performed well over the history of the towns. The river has ceased to flow for at least some period of time in 29 out of the last 72 years. In the past, this has caused chronic, often severe and occasionally desperate water restrictions in Charters Towers. The longest no flow period on record is 7 months.

Generally, the recorded flows in the Burdekin River are significant with a number of studies having been undertaken to construct dams on the river because of the high average flow of the river. Flows required for the three towns upstream of the Burdekin Falls dam are not significant when compared to the average annual flow of the river. It is noted that a proposed dam to be constructed for the "Bradfield" scheme to supply water to southern Queensland was to be constructed upstream of the Charters Towers intake. It is also noted that the water take from the river for community purposes is less than 0.12% of the average flow of the river at the Charters Towers extraction point.

Ground water supplies for Pentland, like a number of ground water supply sources in the region have been consistent; likely failure of these supplies is more likely to be as a result of bore casing or pump failure than a loss of water within the aquifer.

Drought Management Plan - Revision June 2015 Page 9

4.5 Water Consumption

The data available on water consumption for Charters Towers and the other towns provides conflicting results. There has been very little analysis of the consumption patterns over the past few years although it appears that most of the towns have similar water consumption patterns to other similar towns in Western Queensland.

4.5.1 Current Consumption Records for last year (2013/14) indicate the per-capita consumption for Charters Towers City is 1293L per person per day. These figures include all water uses such as irrigation, industrial use and personal domestic use.

5. Drought Management Plan

5.1 General This DMP addresses Charters Towers Regional Council's drought response plan in specific terms. The Drought response plan also considers the Council's ongoing water conservation strategy only in general terms.

It is important that the community understands the difference between the two. Restrictions which are part of the water conservation strategy are ongoing and intended to ensure that we adopt sustainable water use practices as part of our normal way of life. (These are referenced in the plan as the Level 0 restrictions) Charters Towers Regional Council as part of the amalgamation process is developing separate policies on water conservation and an overall reduction in water use.

Restrictions which are introduced in response to a drought or other temporary water shortage events (Level 1 - 4 restrictions) will only be implemented to various levels during the drought or event and will be lifted when conditions return to normal.

5.2 Restrictions Trigger Levels The most effective way to reduce overall water consumption is to introduce water restrictions. Water restrictions theoretically allow the water source to last longer under a variety of usage and drought scenarios taking into account future population growth. In accordance with Section 41 of the Water Supply (Safety and Reliability) Act 2008, CTRC has the legal power to determine, implement and enforce water restrictions.

The Council may decide to have a consistent restriction level in place across the region, in which case the trigger levels for restrictions would need to be set by the level of the Burdekin Weir (14 km from Charters Towers). The water level of the Burdekin Weir is a clear, easily monitored indicator of flow in the river which is the source for most of the supply areas. Table 5-1 sets out the trigger level and restriction levels.

Alternatively Tables 5-2 to 5-4 would allow the Drought Management Team to set various restriction levels depending on more local trigger guides. Because Pentland is not reliant on the same source as the other three water supply areas, it could be left to stand alone with little or no drought restrictions. The trigger levels in tables 5-2 to 5-4 may need to be adjusted as better information becomes available.

Ravenswood is dependent on the supply from the Carpentaria Gold storage, which in turn is fed from the Burdekin River. Level 1 Restrictions are triggered at about the flow where Carpentaria Gold is required to seek permission to continue taking water from the river to maintain the level of the storage. If permission to continue a water take is declined then the Drought Management Response Team may determine to impose greater restrictions at an earlier time. However, in the normal course of events, it is expected that low levels of pumping would extend the life of the supply for both the mining operation and the town. If conditions meant that the river flow was reduced to a point where there was no pumping to storage available then the mine would have a period of time to arrange a managed close down of operations The town usage is so insignificant that further restrictions would not be required until the dam storage is at a much lower level than that normally imposed and while mining operations may be curtailed, the town would have access to water for a significant period of months. Again it is noted that the longest reported period without water is seven months and 10% supply for the town only is likely to exceed that period.

In the tables below, the domestic use target includes domestic water for hygiene cooking and cleaning, and excludes irrigation and outdoor cleaning

Drought Management Plan - Revision June 2015 Page 10

The Trigger levels are a guide. The Drought Management Response Team may determine different restriction levels for each of the supply areas under the control of the service provider if the conditions vary from the predicted rainfall or other patterns.

6. Implementation

6.1 Drought Management Response Team

CTRC has established the following DMP team to be convened by the Chairman on an "as needs" basis to oversee the implementation of restrictions. review performance, conduct post event reviews and recommend any changes to the DMP.

Chairperson: CEO

Team Members:

Mayor

Director Utilities and Facilities

Director Planning and Sustainable Development

Director Corporate Services (Deputy Chair)

Manager Utilities

Portfolio Councillor - Water Resources

Authorising Provision:

The Chief Executive Officer of Charters Towers Regional Council is authorised to impose, amend levels and withdraw restrictions, grant exemptions and initiate prosecutions. The Chief Executive Officer may delegate this authority under the provisions of the Local Government Act.

6.2 Process The Manager Utilities will monitor the level of storage at the Burdekin Weir. As the level decreases toward the first trigger level the Drought Management Response Team will be notified. The Drought Management Response Team will also be notified if other events not specifically mentioned in the document would place a water supply to any of the supply areas at risk.

The Drought Management Response Team will then make a recommendations as to what level of restriction will be applied to each of the supply areas and at what point those levels will apply. The Director Utilities and Facilities and Manager Utilities may make recommendations as to the level of restriction on each supply area and estimates of remaining water.

6.3 Enforcement The CTRC enforces drought regulations through authorised regulatory officers who have the power to issue enforcement notices.

6.4 Exemptions Exemptions to restrictions at each level may be granted in writing by CTRC if it considers that reasonable grounds for such exemptions have been presented to it in writing, setting out the reasons for the exemptions.

Any exemptions may be granted either totally or in part to the extent specified in CTRC's approval notification letter. In most if not all cases, exemptions granted will be for a specified period of time not exceeding the term of the particular level of restriction for which the exemption is granted.

All approved exemptions should be provided with a letter of approval specifying details of the exemption. the reason for the exemptions and the duration of the exemption. This ensures customers have documentation to produce if challenged by a regulatory officer.

6.5 Communications Plan Water and normal level restrictions will be communicated to the community through the regular posted information with the rates notices. As restriction levels increase or in an emergency, the water restrictions and levels will be communicated through the media, using radio and social media in particular.

The following table sets out the communications plan.

1 COUNCIL’S ENVIRONMENTAL POLICY

Charters Towers Regional Council has a number of separate environmental policies and documents covering the range of work carried out by the Council. The Council holds an Integrated Environmental Management System (IEMS) which defines roles and responsibilities, procedures, a site based environmental management plan, documentation and environmental procedures, performance monitoring and training. The document is referenced in this section and can be provided separately if required.

2 WATER RESOURCE DEPLETION AND CONSERVATION

Water-take to meet community needs results in an inherent depletion of water resources.

Demand Management and water re-use is addressed in Appendix N.

3 AESTHETICS

Where possible efforts are made to shield any unsightly water or sewerage treatment facilities from public view. Over the last ten years the Sewerage treatment plant has had significant beutification and vegetation planted for screening purposes. The trees and ponds attract a number of nativie birds and the area is a significant bird wathching environment for tourists and locals. Located in Mosman Creek the Sewerage plant is well away from most community views.

4 ENERGY MANAGEMENT

Energy consumption in providing sewer and water services for Charters Towers City consists of power consumption for pumping. Pump hours are monitored on a weekly basis.

Energy accounts and useage at the water and wastewater pumpstations are checked for significant variances which indicate a maintenance problem with pumps.

Energy consumption is generally not significant for water supply is not considered significant.

Whereever possible water supply pipe networks are designed for gravity flow, to minimise energy costs.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix P Version 1 – November 2009 Page 1 5 SEWERAGE TREATMENT & DISPOSAL

The Environmental Impacts of the Sewerage Treatment Plant are controlled by the procedures in the IEMS and EPA Licensing, the conditions of which are summarised in Appendix H Development Approvals and Conditions.

5.1 SEWER INFLOW & INFILTRATION Sewer inflow and infiltration is being addressed as part of the planned replacement of the sewer reticulation network. This is required to address the poor and failing condition of the sewer reticulation network. Old earthenware pipes are being replaced, and regular smoke testing is required to check for illegal connections of stormwater to the sewer network.

A management plan will be developed to ensure that inflow and infiltration does not become a significant issue. The management plan is likely to consist of monitoring at the Sewerage Treatment Plant to monitor the ratio of Peak Wet Weather to Average Dry Weather Flows (as required for performance monitoring – refer Appendix R), along with standard procedures to investigate sources of inflow / infiltration and undertake repairs where necessary.

The management plan will also include steps the Council will take to ensure that the community is aware that stormwater is not to be connected to the sewer. While illegal connections are considered there is a low risk of illegal connections occurring accidental cross connection is more likely and regular checks of the network are needed to correct major infiltration issues.

5.2 TRADE WASTE MANAGEMENT Council officers currently manage trade waste in accordance with Queensland model Trade Waste Policy and the IEMS.

Generally the requirements for trade waste require industry to ensure there is no contamination of stormwater or sewer water by harmful contaminants. For this area the contaminants are petroleum based products such as oils and fuels, vegetable waste and farm chemicals.

5.3 EFFLUENT MANAGEMENT The Charters Towers Sewerage Treatment Plant complies with EPA licence requirements and meets Class B standards for effluent reuse.

5.4 SLUDGE MANAGEMENT At present, sludge drawn off from the sewerage treatment process is stabilised via drying in sludge drying beds. The dry sludge is then usually stockpiled and buried.

5.5 ON SITE TREATMENT/DISPOSAL Where there is no connection to a reticulated sewage system the Charters Towers Regional Council ensures that property owners have appropriate on site treatement and disposal through the Building Act and the Department of Local Government Planning Sports and Recreation. Private Building Certifiers are responsible for ensuring compliance when approving Development Applications.

It is noted that for systems greater than 20 persons, a licence from the Environmental Protection Authority is required. Currently it is probable that the only sites of this nature within Charters Towers City are National Parks controlled by the Environmental Protection Agency.

SIGNIFICANT FORECASTING ASSUMPTIONS, UNCERTAINTIES, AND RISK MANAGEMENT

1 RISK MANAGEMENT STRATEGY

1.1 GENERAL

The Council's risk management strategy is to complete, implement and maintain risk plans for the principal asset systems, to minimise the likelihood of non-achievement of critical business objectives and to ensure that the impact of system failure is minimized.

The risk management plan defines a process and identifies risk management strategies to minimise risks associated with the provision of the Council services.

The risk management plan is designed to ensure that: • All significant operational and organisational risks are understood and identified. • The highest risks that should be addressed within a 10 year planning horizon are identified. • Risk reduction treatments which best meet business needs are applied. • Responsibilities for managing risks are allocated to specific staff and reporting regimes specified.

1.2 RISK MANAGEMENT PROCESS

The adopted Council risk management process is consistent with Australian/New Zealand Standard AS/NZ 4360 (see Figure Q-1), which defines risk assessment and management. The risk process considers four broad service categories, these being:

1. Risk of service non-delivery (including failure and catastrophe). 2. Risk of non-achievement of required standards (quality non compliance). 3. Financial risks. 4. Risk of financial non-compliance.

Figure Q-1: Risk Management Process

The major elements of the process are: • Risk management context - Establishes criteria against which risk can be evaluated.

• Risk Identification - Identifies the risks the Council may encounter and helps explain the impact of those risks on the service provision.

• Risk Assessment - Establishes a risk rating for all assets or asset groups, and describes which assets represent the greatest risk to the service provision.

• Risk Treatment - Identifies what actions are available to reduce risk at asset or asset group level to an acceptable level, and identifies the most cost effective treatment option.

• Monitor and Review - Ongoing process to ensure risk levels remain acceptable even if risks change.

1.3 RISK MANAGEMENT CONTEXT / EXTERNAL DRIVERS

The key risk criteria adopted by the Council for assessing the consequences of identified risks relating to the provision of water supply services are aligned with the categories of service. They are:

• Loss of Service (Extent and Duration) – aligned with Customer Service driver. • CTRC Business Costs – aligned with Financial Responsibility and Economic Efficiency drivers. • Aging infrastructure will result in a greater probability of asset failure. Asset failure risks and associated consequences will need to be managed to ensure adequate service levels. • Environmental Responsibility. • Safety.

Charters Towers Regional Council Appendix Q Total Management Plan for Water & Sewerage Services Page 2 Version 1- November 2009 • Corporate Profile. • Third Party Property Damage and Loss – aligned with Customer Service driver. • Existing Emergency procedures and related documents.

The following CTRC documents generally describe the procedures relating to risk and dealing with emergency operations. • Charters Towers Regional Council Counter Disaster Plan. • Charters Towers Regional Council Workplace Health and Safety Policy • Charters Towers Regional Council Safety Programme • Charters Towers Regional Council Integrated Environmental Management Plan • Risk Management Assessment (below).

1.4 RISK IDENTIFICATION

Each asset group has been screened considering potential failure modes and events to identify risks. All critical risks and related consequences have been identified. The adopted critical risk reduction treatments will be scheduled in the risk plan of each of the individual volumes.

1.5 RISK ANALYSIS/ EVALUATION

Risk exposure for each key service objective and each risk event is calculated as:

RISK EXPOSURE = PROBABILITY OF x IMPACT OF OCCURRENCE OCCURRENCE

The probability of occurrence used to determine the risk rating is defined in Table Q-1.

Table Q-1: Risk Probability Scale

Likelihood of occurrence Indicative Probability Description within one year (Percent)

Almost Certain 90 Is expected to occur within a 1 year timeframe Moderate 30 Likely to occur within a 2-5 year timeframe Possible 10 Likely to occur within a 6-10 year timeframe Unlikely 5 Likely to occur within a 10-20 year timeframe Rare 2 Unlikely to occur within a 20 year timeframe

1.6 RISK EVALUATION

The matrix of likelihood and consequence of failure ratings shown in the table below is used to assess the level of risk, ranking events as low, moderate, high or extreme risk. This allows all asset and corporate risks to be compared and ranked.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix Q Version 1 – November 2009 Page 3 Table Q-2: Risk Priority Rating Matrix

LIKELIHOOD CONSEQUENCES

1 2 3 4 5

Rare L L M H H Unlikely L L M H E Possible L M H E E Moderate M M H E E Almost Certain M H H E E

The risk policy specifies the following broad treatment strategy for the levels of risk:

L = Low Risk - Manage by routine procedures M = Moderate Risk - Management responsibility must be specified H = High Risk - Risk & management strategy identified in activity plan. E = Extreme Risk - Risk & management strategy identified. Failure management plans available Failure management plan specifically addressing event in place.

Table Q-3 sets out the definitions for the impact ratings assigned for each risk event, defined on a scale of 1 (negligible impact) to 5 (catastrophic impact).

1.7 RISK TREATMENT

The adopted treatment to reduce exposure to 'high' and ‘extreme’ risk events identified are recorded in each detailed asset management plan. Risk reduction treatments available include: • Reduce probability of failure by capital works (renew, provide redundancy and upgrade), maintenance expenditure, operational documentation, training etc. • Reduce the impact of a failure by actions such as preparing emergency response plans. • Accept some risk and carry the consequential costs. • Change the level of service. • Ensure against the consequential costs. • A combination of the above.

The treatment options will be evaluated by an optimised decision-making process, where the risk reduction is considered a benefit. Note that the high cost treatment option may not always give the highest relative reduction in risk.

1.8 COMMUNICATION, MONITORING, REVIEW AND REPORTING

The Risk Management Plan contains a risk register to communicate report and monitor the implementation of the risk policy: • Key Elements - Each key business objective relating to service provision. • Description of the current risk profile. • What can happen? - The things that can go wrong if each of the activities is not carried out properly. • How can it happen? - The specific actions might cause that risk event to occur. • A description of the potential impacts arising from that risk event. • Current Risk Management Strategies - The practices that are currently carried out to manage those risks. • Residual Risk Assessment - Identifies the residual risk remaining after risk management strategies have been implemented. • Risk management Processes - Project task sheets prepared to implement the risk management plan.

Even so, it needs to be accepted that some risks will always be “extreme” regardless of intervention / risk management strategy. These risks will be those with rare or unlikely occurrence but with catastrophic results. These risks are outside of human control and a recovery strategy is more applicable.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix Q Version 1 – November 2009 Page 5 2 SIGNIFICANT RISKS

Table R-1: Summary of Levels of Service and Performance Measures

Charters Towers Regional Council Customer Service Standards for Water Supply & Sewerage Services Version 2 – revised December 2014 2 1 INTRODUCTION

Levels of service are based on Council’s statutory obligations and annual planning, currently accepted industry standards and community expectations as assessed from verbal and written comments received from the community.

Ongoing monitoring of community expectations will be required to ensure delivery of levels of service. 2 OVERALL PERFORMANCE OBJECTIVE

The overall objective is:

• To deliver adequate quantities of water to every property connected to the distribution system while maintaining water quality to the NHRMC Guidelines at the agreed level of Service. • To transport waste water effluent (sewage) from properties in Charters Towers within the designated sewerage area to a waste water treatment facility (subject to the physical limitations of connection).

This document is CTRC’s Customer Service Standard (CSS) Document.

3 PERFORMANCE MEASURES

3.1 WATER SUPPLY QUALITY

The quality of water provided is based on a number of typical measures which are set out below. In the context of a rural community such as Charters Towers the quality of water supplied and the expectations of the community will be significantly different to the quality and expectations of a large town or city. 3.2 CUSTOMER SERVICE STANDARD TARGETS AND MEASURES

Table R-1 shows a summary of the levels of service, performance measures and relationship to community outcomes for water supply.

The primary targets and measures will be reported in the Annual Report.

Charters Towers Regional Council Customer Service Standards for Water Supply & Sewerage Services Version 2 – revised December 2014 3

Table R-1: Summary of Levels of Service and performance Measures

Performance Indicator Target Water Supply – Continuity Water main breaks per 100km mains/year <20 (152.5 km installed) Unplanned interruptions per 1000 100 connections/year (4,464 connected) Response time to all events 3 hours (City) 6 hours (remote communities) Water Supply - Adequacy Minimum water pressure and/or flow expectation >15m or 15l/min at boundary Water Supply - Quality Compliance with Australian Drinking Water Yes Guidelines – microbial guideline values Drinking water quality incidents/year 1 (City) <5 (Rural) Sewer Supply - Continuity Total Sewer Main Breaks per 100km mains/year 15 (95.9km installed) Total Sewer chokes per 100km mains/year 25 (95.9km installed) Complaints for failure to meet targets Drinking water quality complaints per 1000 6 connections per year (4,464 connected) Wastewater odour complaints per 1000 properties 5

Generally speaking, in the medium and small systems operated by Charters Towers Regional Council, most interruptions to service result from minor breakages and leaks. In the Charters Towers environment most services will not experience a significant interruption although in percentage terms the numbers could appear significant. People living in remote and rural areas are more likely to accept a lesser service than those living in a major city, and tend to have a reserve supply to deal with loss of service.

Table R-1 summarises the agreed levels of service for the CTRC schemes. The Council has programs in progress which will develop a performance database to capture information on service standards, and these are part of a system improvement plan item. The forms expected to be used are:

• Service complaints/ Action request form • Planned service interruption record – Water Supply

Charters Towers Regional Council Customer Service Standards for Water Supply & Sewerage Services Version 2 – revised December 2014 4 • Summary physical water quality (EHO records)

The database is to be developed to link the information captured on the above forms to the performance targets established in Table R-1. This will allow performance monitoring to occur against the agreed levels of service. 3.3 COMMUNITY CONSULTATION

Community consultation on the Customer Service Standards has not yet been undertaken for the development of this document. A community consultation consisting of a questionnaire on overall Council performance and assets related issues may be carried out once the Regional Council has had the opportunity to develop combined procedures and documentation for its asset management systems.

4 CUSTOMER SERVICE PROCESSES 4.1 SERVICE CONNECTION PROCESS Customers are required to apply in writing to Council for any new service connections for water or sewerage by way of a service request. The request is then processed to identify what costs are applicable, dependent upon the area in which the connection is to occur. The customer will be provided a written response identifying all applicable costs and the timeframe within which the service connection can be made.

4.2 BILLING, METERING & ACCOUNTING PROCESS Water meters are read once per year commencing on the 1st Monday of June annually, with readings across the region taking approximately 2 weeks. Readings are actioned in order of routes, and the sequence in which the routes are read each year are the same. This results in as close as possible to 365 days between each read for each property. Based on this timing, water usage charged on each rate notice covers the period from the beginning of June in the previous year through to the end of May in the year of levy.

Water rates and any applicable excess water charges, along with sewerage rates are levied once per year through the issuing of a Rate Notice.

4.3 CUSTOMER REQUESTS AND COMPLAINTS PROCESS Council has a system for the recording both Customer Requests and Customer Complaints. A Customer Request is considered as a request for Council to take action to satisfy the needs of a customer or ratepayer. This may be of a physical nature, such as a request to fix a leaking water Charters Towers Regional Council Customer Service Standards for Water Supply & Sewerage Services Version 2 – revised December 2014 5 meter or connect a property to water. If no action or inadequate action is taken in regards to a Customer Request for service or information, then the subsequent contact would be considered a Customer Complaint.

A Customer Complaint is considered as an expression of dissatisfaction, orally or in writing, about the service, decisions or actions of the Council or its staff; or the conduct or performance of a councillor of a local government. It is not an enquiry or service request, unless the person specifies that they wish to make a complaint.

Customers are able to contact Charters Towers Regional Council in person, over the phone, via email or through the website to report a Customer Request or Customer Complaint. All Customer Complaints are handled through Council’s Complaint Management System in accordance with Council’s Statutory Policy – S0014 – Complaints Management Policy and Procedural Guideline.

1 OVERVIEW

CRTC has improved the quality of its water and wastewater management practice over the past five years. However, the amalgamation of the Dalrymple Shire Council and the Charters Towers City Council in March 2008 has resulted in a number of systems and the body of knowledge on the assets needing to be collated, reviewed and combined into one asset system.

Performance monitoring and data collection is a key area where CTRC needs to improve.

1.1 ASSET KNOWLEDGE PROCESSES AND DATA

Data management processes to ensure data accuracy and completeness have improved primarily as a result of consultant activity, although process improvements including auditing should be considered in line with overall QA improvement activities.

Most network asset attribute and asset maintenance data is contained in databases to a medium degree of accuracy and completeness. However, there remains too much reliance on local knowledge. Whilst combining the data into suitable databases information shall be checked and reviewed.

Opportunities exist to improve the analysis of the existing maintenance data.

Asset Attributes Attribute data for water supply assets is to be stored in four conveniently accessible formats:

1. Hard copy form 2. Excel database 3. GIS software 4. Database held off site.

The information, although known to be incomplete and of variable accuracy, is generally satisfactory. Development of the database system is expected to improve the level of confidence in the asset attributes

Inspection forms will be developed for use in capturing attribute data during the routine daily operation of the networks. The efficient operation of water supply assets is reliant on the knowledge of experienced staff.

Condition Data There is limited condition information becoming available on water supply assets, with replacement decisions based on the experience and knowledge of key staff. ASSETA information should improve the quality of condition data.

Spatial Data The positions of hydrants and valves in all schemes need to be fixed accurately by GPS, and stored in the GIS system.

Works Activity Data Records are currently in the Water Management database. This database records customer complaints, all works (both reactive and preventative), and some record of expenditure.

Condition data is interpreted from: • Preventative maintenance inspections routinely undertaken to monitor the condition of treatment plants and pump stations.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix S Version 1 – November 2009 Page 1 • Specific consultant investigation of the waste water network. • Targeted investigations into water mains and fittings where performance is outside the targeted level of service. • Failure records, enhanced by the established reporting format for all pipe failures (e.g., pipe bursts and leaks) whereby the Contractor records the location of the fault, reason for the failure, state of pipe exposed, ground conditions and the cost to repair. • Other opportunistic capture from maintenance forms. • Performance (capacity) information is maintained through: - Water quality testing undertaken at random locations within the water supply network to monitor compliance with drinking water standards. - Telemetry monitoring of the key operational parameters of the pump stations. - Investigations undertaken in response to summary reports of loss of pressure in parts of the network.

1.2 STRATEGIC PLANNING PROCESSES

Available data to be able to reasonably forecast future funding requirements due to condition/structural failures or capacity failures is limited to identify problem areas. CTRC needs do not justify the expense of developing more sophisticated, bulk condition assessment methodologies or performance models at this stage. However, linkage with more rigorous risk analyses, further development of condition-based failure analysis methods and fuller use of available data to improve long term financial forecasts ranks as a high priority for strategic planning. A suitable risk management framework is in place, and there are opportunities to further develop risk analysis as a basis for decision-making.

The process for successfully determining community expectations and preferences relating to service standards and cost of service ranks as a high priority, needs to be undertaken in the context of the community’s capacity to pay. A job costing system is used, to enable the cost of each work activity to be calculated, for budgeting and financial control.

Economic decision making processes to optimise investment in capital renewal and development works are based on the assessments of experienced staff with consideration given to lifecycle costs. Identified improvements have been noted.

1.3 ASSET CAPITAL PROCESSES

Contracts are competitively let for the delivery of major repair, rehabilitation, renewal, upgrading and development work, generally where the likely cost will exceed $100,000. CTRC and Charters Towers Water have their own staff to carry out most of the work on projects valued at less than $100,000 in house.

Some processes are in place for formal prioritisation of projects, but there are opportunities to improve project selection (to take into account lowest lifecycle costs), justification and prioritisation.

1.4 OPERATIONS AND MANAGEMENT PROCESSES

• Operation, maintenance and inspection standards are defined (and documented) in internal service level agreements. • Records are kept of all maintenance and repair works in an excel database. • CTRC staff make decisions relating to the optimal balance of planned/ reactive maintenance work. • Contract monitoring and control processes are robust, although there may be opportunities to improve them as part of our quality plan.

Charters Towers Regional Council Appendix S Total Management Plan for Water & Sewerage Services Page 2 Version 1 – November 2009 • Good emergency response plans exist. • Council’s Corporate Plan identifies Human Resource Development as a key component of its Administration and Finance objectives. • The following Council employees are directly involved in the provision of water and sewerage services: - Works Supervisor (water and Sewer) - Plumbers - Sewerage treatment plant operator - Testing officer/laboratory manager. Other Council employees including the Director of Engineering, Engineer and administration/financial staff support these operational personnel. • Council has a Human Resource Policy as well as a number of individual policies within the suite of documents that make up the Council Human Resources Policy. Council also has a documented Quality Management System, a Workplace Health and Safety System including a documented Safety Program and an Employee Rehabilitation Policy. • A WH&S Plan is developed for any capital works project. • Council employs a WH&S officer. • WH&S training is documented for each staff member and recorded by the WH&S officer. • All supervisors are undergo a Stage 1 Safety Officer course as defined by the WH&S Act 1995. • All new employees and visitors complete a construction safety induction programme. • The job skills training budget is determined on an ‘as needed’ basis. No formal ‘on site’ training is carried out. • There is a lack of “back up” expertise if key staff members are away or leave the organisation due to the small staff numbers in the water and waste water area.

1.5 INFORMATION SYSTEMS

Council has a formal Information Technology policy. Council has a commercial arrangement with Practical Computer Systems (PCS) for its financial management program.

Information systems include an asset register which uses the PCS accounting system for recording assets and cost information.

Information systems are managed by the Corporate Services Area of Council and are tailored to meet the financial and asset management needs of Council.

The following Information System Packages are used in the Water and Sewerage Activity:

• Asset Register – Practical Computer Systems Asset Register.

• Accounting – Practical Computer Systems Accounting Package.

• Documentation Control – Dataworks.

• Geographical Information – MapInfo.

1.6 ORGANISATIONAL / COMMERCIAL STRATEGIES

• Good structures have been set up in CTRC to progress activity management in a consistent way.

Charters Towers Regional Council Total Management Plan for Water & Sewerage Services Appendix S Version 1 – November 2009 Page 3 • Contracting strategies are generally well developed and effective service agreements are in place with internal service providers. The strategies require review to ensure they remain relevant in view of the greater understanding now available of network condition and performance. • CTRC has recognised that audit procedures are not well defined for controlling the quality of either data (work activity, financial, attribute and spatial data) or physical works. This will be an area of development for the 2008 - 2012 asset management plans. • CTRC has a quality and continuous improvement culture. A greater focus on a structured approach to training needs assessment and succession planning is considered beneficial. • Human Resource management is subject to the following legislation: - Queensland Local Government Act 1993. - Workplace Health and Safety Act 1995. - Workplace Relations Act 1996/97. - And, various Anti-Discrimination Legislation. • Councils must maintain their TMP to the satisfaction of the Department of Natural Resources (DNR) to be eligible for subsidies. This implies that Councils need to provide sufficient resources for effective implementation of their TMP. • There is currently a trend towards outsourcing of services. Any decision to outsource should be supported by an appropriate analysis of impacts on its human resources, both beneficial and adverse. • Development of the TMP has identified a number of management strategies that will need to be implemented over the next three years.

1 ACTIVITY IMPROVEMENT PLAN

CTRC has adopted a strategic management approach to improvement planning, continually developing activity management plans and implementing improvement processes. This Improvement Plan is integral to that approach, quantifying current business practice and measuring progress toward an identified future position.

The purpose of the Improvement Plan is to: • Identify and develop implementation of activity planning processes • Identify and prioritise ways to cost-effectively improve the quality of the activity plan • Identify indicative time-scales, priorities, and human and financial resources required to achieve activity planning objectives • Serve as the basis for project managing the improvement tasks

As this is the first Version of the TMP for Charters Towers Regional Council, all previous plans have been ignored to establish a baseline plan. A number of documents held by both the Dalrymple Shire Council and the Charters Towers Regional Council need to be combined to create a current document set, this TMP is one of the first documents to combine the information of both councils and requires at least a full year of implementation before a review is completed.
