41/14840/333302 South East Queensland Regional Water Supply Strategy Bulk Supply Infrastructure Task Group Desk Top Review and TOR Development Consultancy 1. Introduction

1.1 Background The Terms of Reference (TOR) for the “South East Queensland Regional Water Supply Strategic Project Bulk Infrastructure Task Group” (RWSS) require a desktop review and TOR development (BSI-04) be undertaken in four parts as follows:

Part 1 – Review of Gold Coast Water Supply Options;

Part 2 – Review of Other Augmentation Planning;

Part 3 – Desktop Review of Identified Dam and Weir Sites; and,

Part 4 – Preparation of TORs for Further Consultancies. A sub-requirement of Part 3 of the consultancy is the preparation of scoping reports indicating:

The proposed scope of work for this task;

A refinement of the cost estimates for the task (exclusive of in-kind work by the Bulk Supply Infrastructure Task Group);

A proposed methodology for screening dam and weir sites with a view to updating cost estimates only for those projects worthy of further analysis;

Identification of any work contribution required from the BSI Task Group; and,

A proposed schedule for the work for this task giving regard to timing of outputs required to other BSI Tasks and to other task groups. An initial scoping report is required under Part 3 summarising infrastructure options identified, with recommendations regarding which projects are to be included for further analysis as part of the desk top study. This report constitutes the initial scoping report. Following BSI Task Group approval of the options to be included for further review as outlined in the initial scoping report, a further scoping report is required which refines the scope and proposes a work schedule for the specific options to be further considered in the desk top review.

1.2 Objective of Part 3 The overall objective for Part 3 of the consultancy is to address the work required under Task BSI04 “The Desk Top Review of Identified Dam and Weir Sites” as outlined in the Bulk Supply Infrastructure Task Group Scoping Paper, which was attached to the brief for this consultancy. Consequently, the consultant is to:

Acquire and review existing information on previous investigations; and,

Prepare and submit to the Project Officer, a Report (the BSI04 Report) summarising the Infrastructure Options identified from a review of the existing reports and information, with recommendations on which warrant further

41/14840/333302 South East Queensland Regional Water Supply Strategy 1 Bulk Supply Infrastructure Task Group Desk Top Review and TOR Development Consultancy consideration, and identification of the further investigation required to firm up the information on these sites. The initial scoping report is the first report in a series of reports with the overall objective to:

Identify possible infrastructure options to improve water supply including: – New dams and weirs; – Existing dams or weirs that could be raised; – The associated delivery infrastructure; and,

Determine which of the identified infrastructure options warrants detailed investigations and eliminate all others from further consideration. Each of the previous studies is to be evaluated to identify any major gaps in information on aspects such as environmental impact, cultural heritage or foundation conditions giving particular attention to the identification of potential “show stoppers”.

A report (the BSI04 Report) is to be submitted to the Project Officer incorporating the following:

The costs associated with the development of selected sites to a range of capacities, including land acquisitions and modifications to infrastructure such as roads and powerlines. The costs are also to be shown in schedules including quantities, unit rates and allowances for overheads and contingencies. Plans showing arrangements of structures, relocations, resumption areas etc are also to be provided;

Recommendations on further studies (including costs and timelines) necessary to assess potential “show stoppers”. These recommendations will also be provided progressively in a series of interim reports and will lead to the preparation of TORs for work under BSI 05;

Recommendations on the infrastructure necessary to connect the storages to the regional network (identified in broad terms) together with preliminary cost estimates of pipelines and water treatment;

Recommendations on the infrastructure necessary to connect the storages to the regional network in broad terms together with preliminary cost estimates of pipelines and water treatment; and,

TORs for BSI 05 provided progressively. In addition an oral presentation of the findings will be made to the Bulk Supply Infrastructure Task Group and the Strategy Management Group on completion of the task.

41/14840/333302 South East Queensland Regional Water Supply Strategy 2 Bulk Supply Infrastructure Task Group Desk Top Review and TOR Development Consultancy 2. Proposed Scope of Works

2.1 BSI 04 Desk Top Review of Identified Dam and Weir Sites Subject to approval of the Initial Scoping Report by the BSI Task Group, a more detailed review of the existing Investigation Reports and Preliminary Designs will be undertaken and the costs will be updated on a common basis. This may require some new desktop preliminary design where modification from previous arrangements is desirable, or where existing information was insufficient. Some desk top preliminary design may also be required for the delivery infrastructure on an individual basis recognising that water demand and points of delivery will not be fully understood. After screening to determine the sites with the greatest potential, a range of capacities will be assessed to determine the upper limit for development at each of the sites. Whilst this upper limit may result in a higher cost per megalitre than an alternative the marginal cost may be less than the marginal cost of the next alternative. At least two capacities are to be investigated at each site: the nominated capacity and the upper limit. The tasks to be undertaken include:

Identify all the sites to be considered in the desktop review. The BSI Task Group Scoping Document attached to the brief for this consultancy suggested that this is likely to amount to five or six new dam sites, three potential raisings and up to four weir sites, though the brief itself and review of existing reports to date have suggested an increased number of sites will need to be considered;

A review of the infrastructure projects nominated by the Steering Committee Workshop 27th January 05;

Review of the existing documents on previous investigations including the cost estimates and identify shortfalls;

Review any previous assessments of environmental and cultural heritage impacts. Carry out additional desktop studies where appropriate in order to develop an appreciation of whether potential impacts may affect the likelihood of the proposal proceeding and identify those sites unlikely to be developed due to social or environmental impacts;

Prepare updated cost estimates based on the available information and form an appreciation of the accuracy of the estimates, for those projects that might be considered further in the development of the RWSS;

Identify in broad terms the infrastructure necessary to connect the storages to the regional network;

Prepare preliminary estimates of the costs of this connecting infrastructure and water treatment;

41/14840/333302 South East Queensland Regional Water Supply Strategy 3 Bulk Supply Infrastructure Task Group Desk Top Review and TOR Development Consultancy For competing options, for example, alternative weir sites on a river or alternative pipeline routes, determine which is preferable considering cost, supply and impact criteria;

Prepare a list of options that appear to be feasible and preferred;

Prepare, following consultation with the BSI Task Group, for each site included in this program, a schedule of additional (pre-feasibility level) studies required to confirm that the project warrants detailed investigation, including estimated costs of the studies;

Prepare a risk management assessment for each site/project in the context of it being struck off the list or included for further consideration;

3.2 Dam and Weir Water Supply Projects The potential water supply improvement projects mentioned in the 27th January Workshop are summarised in Appendix A and of these bulk water supply options associated with dam and weir developments were:

Glendower Dam Feasibility (investigation);

Upper Mary Coles Crossing Weir and Noosa Pump Station;

Ewen Maddock Dam rehabilitation; and,

Wyaralong Dam site acquisition.

A summary of the information on the dam and weir projects referred to in the reports listed in Section 3.1 (Ref 1 to 6) are provided in the tables in Appendix B with each project tabulated according to the potential yield identified in the previous reports. The yield was assessed a number of years ago. Since then procedures have changed and additional data has now become available. Yield analyses will be undertaken on the projects with the greatest potential. It is anticipated that these yield estimates will result in a reduction in the potential yield from a number of these projects. The projects have been subdivided into four supply capacity options so that the projects can be reviewed on the basis of their potential benefits. The supply categories chosen were:

Potential bulk water supply greater than 50,000 ML/a;

Potential bulk water supply between 20,000 and 50,000 ML/a;

Potential bulk water supply between 5,000 and 20,000 ML/a; and,

Potential bulk water supply less than 5,000 ML/a. The categories were chosen to categorise options that at the upper supply range had the potential to supply water to the entire region and in the lower supply range would result in supply only to the local area. More than 80 bulk water supply options have been assessed in the existing reports. The general characteristics for these options are summarised in Appendix B, and the location of each of the sites are indicated in Figures 1-A and 1-B. A number of these sites have variations in potential storage capacity and yield from one source of information to another.

41/14840/333302 South East Queensland Regional Water Supply Strategy 6 Bulk Supply Infrastructure Task Group Desk Top Review and TOR Development Consultancy 3.3 Cost per ML/a Yield Cost to supply the anticipated yield has been determined for a number of the sites listed in Appendix B based on. :

The escalated cost of the projects as indicated in the appropriate reports. Generally the costs include the capital cost for the works, land acquisition and infrastructure relocation costs. However for some of the cost estimates it is not clear whether all the above costs have been included. Bulk water supply transfer costs generally have not been included in the costs provided in the previous studies and therefore has not been included here.

Cost estimates provided in the reports have been escalated to July 2005 using a combination of the Rawlinsons building price adjustment and the Rider Hunt tender level index. This has been undertaken to provide a reasonable comparison of costs between the various reports. Both these indexes indicate a significant increase in costs over the past three years when compared to previous years. The Rawlinsons index indicates much greater increase when compared to the Rider Hunt Index. The Rawlinsons index for Brisbane is reported to provide a good guide to building cost increases over the past two years and reflects the shortage of labour and materials being experienced in the industry. As the bulk water supply projects are a mixture of building and civil construction and as it is anticipated that the cost increases currently being experienced may be short term in nature the cost index chosen for escalation was a mean of the two indexes.

The yield estimates given in the reports are currently considered to be optimistic, however, these have been used for the comparison of projects as it is likely that all of the projects will be impacted by a similar proportion when the additional drought information and new calculation techniques are taken into account. In reviewing the costs it was found that there were four types of project:

Existing dams not currently utilised that may provide a small increase in yield for the system;

Projects previously costed and able to be compared;

Projects that have not been costed but may have potential; and,

Projects that were favoured but had been excluded previously on social or environmental grounds.

3.3.1 Dams Returned to Service Projects identified that are likely to increase the available water supply to the community and are likely to be of very low capital cost to return to service are identified in Table 1 below, though these projects were considered of local significance only.

Yield (ML/a)

Ewen Maddock Dam (return to service) 5,000

Lake Manchester, Enoggera and Gold Creek Dams (return to 12,000 service)

3.4 Recommended Sites for Further Review In general the reports indicate that there are environmental or social issues on most, if not all of the projects. The earlier reports have not been assessed on the basis of potential green house gas production/ energy consumption as a result of pumping etc or the potential to manage the environmental/social risks with engineered works. The environmental impact relative to the benefit has not been evaluated. Each of the sites was reviewed on the basis of the potential yield as indicated above, the potential environmental constraints as identified in the available reports and the potential social issues as identified in the previous reports. A summary of some 80 identified sites is included as Appendix B. Of these 14 dam sites and a water harvesting option were considered to be appropriate for more detailed review. These are indicated in Table 2:

It is expected that the BSI Task Group or its representative would:

Arrange for updated yield assessments for appropriate dam and weir sites. Those projects requiring updated yield information are summarised in Table 2.

Assist with co-ordination to manage the exchange of information with other task groups;

Obtain relevant reports or results of the studies from the other task groups and make this information available to the further work as required, especially updated yield information;

Provide contacts within the other task groups to enable the further consultants to liaise as required;

Organise logistics associated with the oral presentations by any consultants to the BSI Task Group;

Be responsible for reviewing and providing comment on draft documentation produced by the consultants; and,

Gain approval/advice from the State Government, South East Queensland Regional Organisation of Councils (SEQROC), and the Regional Coordination Committee (RCC) as appropriate before formally identifying such sites/projects.

41/14840/333302 South East Queensland Regional Water Supply Strategy 11 Bulk Supply Infrastructure Task Group Desk Top Review and TOR Development Consultancy 5. Proposed Timings

5.1 What can be started now? The work to be completed in Part 3 can be started now and has commenced with the summary of projects previously identified.

5.2 Proposed Schedule The Terms of Reference require that a draft of the BSI04 report be submitted for review on 28th October 2005. The completion of this task is dependent on:

Yield estimates being provided in a timely manner;

Approval of the BSI Task Group of the projects to be included in the report;

Responses from the Councils and Water authorities being received in a timely manner;

Availability of suitable topographic plans for the sites being considered;

Engineering analysis of previous reports and data plus development of engineering options;

Availability of ecological, social and archaeological information on the sites/projects; and,

Identification of the demand requirements and locations of the demand centres suitable for pre-planning of the raw water distribution requirements.

This means that the proposed schedule may need to be amended depending on when inputs are available from other tasks or task groups. If the relevant inputs are available when required the engineering assessments could be completed by 28th October 2005.
