4.1 PUBLIC LIGHTING PREFERRED LED LUMINAIRE FOR LOGAN CITY COUNCIL
REPORT OF: Road Infrastructure Planning Manager
REPORT OVERVIEW
EXECUTIVE SUMMARY The purpose of this report is for Council to consider the preferred LED luminaire within the public lighting network throughout Logan City. Criteria: Direction - It requires Council to make a decision of a strategic nature; or Council has specifically requested it CORPORATE PLAN PRIORITY Quality Lifestyles
RECOMMENDATIONS
IT IS RECOMMENDED: That the 4,000k (cool light) be endorsed as the standard LED light utilised within the Logan City public lighting network to replace the Mercury vapour luminaries on failure by Energex, as detailed in the report of the Report Infrastructure Planning Manager dated 25 January 2021.
REPORT DETAILS
INTERESTED PARTIES Energex Road Users PURPOSE OF REPORT/BACKGROUND Council has been historically responsible for the provision of public lighting services, utilising over 33,000 public lighting assets (streetlights), of which the vast majority are owned by Energex. The objective of road lighting is to increase the safety and amenity of pedestrians in public areas and to improve traffic safety and operation at intersections and hazardous locations. There has been sustained pressure from South East Queensland Councils to introduce LED lighting for the public lighting network. As a result, within the Energex distribution for the regulatory period 2020- 2025, a new LED lighting tariff category has been introduced. Energex currently have two (2) preferred LED lights which can be rolled out throughout the network: i.e. 3,000K (warm light) and 4,000K (cool light) As per the request from Energex (Attachment A), Energex is seeking a determination from Council as to the preferred LED replacement luminaire for the public lighting network within Logan City. DISCUSSION
Logan City Council’s Public Lighting Inventory The current inventory of Logan City Council public lighting network is as follows:
Report Page 1 of 5 Page 4 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
The definition of current public lighting tariff categories are as follows: NPL1 - are public lighting assets which are owned and operated by Energex.
NPL2 - are public lighting assets which have been gifted to Energex and are maintained by Energex.
NPL3 – are public lighting assets which are owned and operated by Council.
Energex Roll out of LED Energex and the Australian Energy Regulatory (AER) introduced new LED lighting categories/tariffs for the 2020-25 regulatory period. The rollout of LED allows for both customer-led transition, as well as that led by Energex. Energex have set a target penetration for LED lighting of 47 per cent by the end of the 2020–25 period throughout the entire network. This reflects the strategies put forward in their asset management plan that: All new and additional lights installed are to be LED
75 per cent of mercury vapour lamps and luminaires are to be replaced with LED during the 2020–25 period
20-25 per cent of life-expired/failed conventional lights are to be replaced, gradually increasing to 30-40 per cent by 2025. However, Council has not received any program of works from Energex for an accelerated roll out of LED public lighting within Logan City and are currently only replacing lights on a failure basis. Based on history this is approximately 350 mercury vapour lights a year.
Report Page 2 of 5 Page 5 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
LED Lighting Public lighting technology has advanced significantly in recent years. LED Lighting has become the dominant technology for most new public lighting upgrades around the world. LED public Lighting conversion reduces energy consumption and greenhouse gas emissions, improves visibility and the lights have a longer life span. All new developments within Logan City are currently being installed with LED luminaires. Under the Minamata Convention, production of mercury vapour lamps will be banned from import, export and manufacture in most Countries. The rollout of LED lights to replace the existing network, especially mercury vapour will provide a number of benefits to the community in alignment with Corporate Priorities:
Improved visibility for both road and pedestrian safety Reduction in Greenhouse gas emissions. It is forecasted that for each lamp replaced the Greenhouse gas emission is reduced by 0.20 tonnes per annum
Reduction in KWh usage of the network. It is forecasted that 65% reduction of kWh usage would be achieved for each lamp replaced.
Potential financial savings. The replacement to LED luminaires reduces both the consumption and network charges of the electricity invoices. LED Luminaire Options Energex currently have two (2) luminaires available for use throughout the network, a 3,000K (warm light) and a 4,000K (cool Light). LED colour temperature is a description of the warmth or coolness of a light source. The Kelvin (K) is a unit of measurement for colour temperature. A practical way to demonstrate colour temperature is by example. A candle produces a warm glow with a yellow/orange appearance. In contrast, incandescent lamps produce a cool light. The 3,000K LED light has a larger mix of yellow, but still not nearly as yellow looking as a halogen lamp. The 4,000K LED appears as a ‘cool white’ light when viewed on its own, but when compared to higher Kelvin lights it does appear to contain some yellow. It is not as stark white (cold looking) as a 5,000K LED. The 4000K LED is closer to a natural daylight which is useful when identifying colours at night. The Colour Render Index (CRI) is improved under the cool colour temperature. This is also beneficial when being used in conjunction with CCTV to identify a person or object. To warm the colour of the LED, phosphor is added to the LED chip. The greater the phosphor added to the chip the less efficient the light is. There is approximately a 3% decrease in output from the 3000K LED compared to the 4000K LED. In addition, several trials have been undertaken with the use of lights from a traffic management perspective. The 4000K light performs better than the 3000K in most areas, by throwing a better light with less glare.
Report Page 3 of 5 Page 6 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
An illustration of the output of the different lights is documented below: 4000K 3000K
Energex’s preferred light to be utilised throughout the network is the 4,000K (cool light). If some instances, Council may require the use of a warmer light (3,000K) for a specific project due to environmental reasons or operational outcomes. In these instances, Council will still reserve the right to utilise the warmer light based on these project outcomes. ANY PREVIOUS COUNCIL DECISIONS There are no previous Council decisions made in relation to this matter. FINANCIAL/RESOURCE IMPLICATIONS There are no financial implications associated with this matter. RISK MANAGEMENT IMPLICATIONS There are no additional risks associated with this matter. LEGAL/POLICY There are no legal/policy matters associated with this matter. COMMUNITY AND OTHER CONSULTATION Consultation and a demonstration occurred between Council officers and the City Infrastructure Committee Chair of the two different lights, where the preferred light was the 4,000K LED. Consultation has occurred across the relevant branches within Council.
Report Page 4 of 5 Page 7 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
CONCLUSION Within the Energex distribution for the regulatory period 2020-25 a new public lighting tariff has been introduced for LED lighting to be installed within the Network. Logan City Council has made substantial progress in implementing LED lighting for all new installations and will continue to collaborate with Energex to expedite any future potential expansion. As part of this new reform Energex is seeking advice from Councils as to the preferred LED luminaire to be used within the Local Government boundary. Energex preferred light for replacement is the 4,000K (cool light).

4.3 ROAD NAME CHANGE - PART OF BAHRS SCRUB ROAD
REPORT OF: Road Infrastructure Planning Manager
REPORT OVERVIEW
EXECUTIVE SUMMARY This report seeks Council to approve the renaming of part of Bahrs Scrub Road, Bahrs Scrub as outlined in the background map. Criteria: Direction - It requires Council to make a decision of a strategic nature; or Council has specifically requested it CORPORATE PLAN PRIORITY Conveniently Connected
RECOMMENDATIONS
IT IS RECOMMENDED: 1. That, in accordance with Council's Policy titled ‘hanging of Names of Roads’ and as detailed in the attached map (Attachment 1) to the report of the Road Infrastructure Planning Manager dated 25 January 2021, the renaming of part of Bahrs Scrub Road, Bahrs Scrub, be endorsed. 2. That the Road Infrastructure Planning Manager be requested to advise the affected owners, residents and service providers of the road name change, as detailed in Clause 1 above, with an effective date of 5 April 2021.
REPORT DETAILS
INTERESTED PARTIES Local community impacted by the proposed road name change Developer for construction of unformed road reserve Development assessment branch Division 6 Councillor PURPOSE OF REPORT/BACKGROUND The purpose of this report is to change the road name for a section of Bahrs Scrub Road, Bahrs Scrub as identified in the background map. The proposed road name change is important to maintain the road function intent of Barhs Scrub Road, Bahrs Scrub as per the Local Development Area Plan (Attachment 2). A perspective developer has already made an enquiry for the change through Development Assessment branch. Endorsed Bahrs Scrub Local Development Area Plan (Attachment 2) shows an east - west movement occurring along Bahrs Scrub Road, through an unformed road reserve connection to Hein Road. Bahrs Scrub Road is planned to be an urban collector road as per road hierarchy outlined in the Planning Scheme 2015.
Report Page 1 of 3 Page 17 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
With the construction of this link between Bahrs Scrub Road and Hein Road, it is proposed to change the name of the section of Bahrs Scrub Road, Bahrs Scrub identified in the attached map to Old Bahrs Scrub Road. The change will not require existing property numbering change. ANY PREVIOUS COUNCIL DECISIONS Not applicable.
FINANCIAL/RESOURCE IMPLICATIONS Not applicable. RISK MANAGEMENT IMPLICATIONS Not applicable. LEGAL/POLICY Not applicable. COMMUNITY AND OTHER CONSULTATION Letters were sent to all 11 affected owners and residents seeking feedback specifically if not in favour of the proposed change. Subsequently four (4) responses were received. Two (2) were supporting the change if necessary. The other two (2) made suggestions; One (1) requesting to change the name of the ‘to be constructed’ road, and the other requesting the identified section of the road be named Bahrs Scrub Road West. The unmade part of Bahrs Scrub Road will make an important collector road function connection to Hein Road as per the Council endorsed Local Development Area Plan and will carry the dominant flow of traffic. This means leaving the current road name (i.e. ‘Bahrs Scrub Road’) for the section proposed to be renamed would not be appropriate, as it would be unusual and confusing to the motorists, with a far greater potential of leading them to a dead-end road. These are compelling reasons for changing the road name. The suggestion to rename the road as ‘Bahrs Scrub Road West’ instead of the proposed change, appears to be based on personal preference by the responding resident. The resident also has enquired about cycle paths. The cycle path request is unrelated to the purpose of this report and will be addressed separately. These matters have been discussed with Cr Tony Hall, Division 6 Councillor and Cr Hall was supportive of the proposal to progress. Separate emails have been sent to both residents thanking their feedback and outlining the intent of the road name change and the reasons to proceed with the proposal. With the majority of resident’s accepting the requirement for a name change, it is established that the proposed change meets the criteria of Council's policy for 'Changing of Names of Roads' as outlined in section 2(c) as follows:
Report Page 2 of 3 Page 18 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
2. A road (or roads) will be renamed subject to satisfying one or more of the following: (a) The divisional councillor supports the change of road name when 90% or more of owners and residents in the affected road or roads support the proposed renaming. (b) Council resolves the change of road name, when sufficient evidence exists to consider the road name change is reasonable and/or essential where use of the existing road name could cause potential confusion for operations of emergency services, agencies and/or delivery organisations. (c) Council resolves the road name change, considering all other factors, when 70% or more owners and residents in the affected road or roads support the change. CONCLUSION In accordance with Council policy titled 'Changing of Names Roads', the identified section of Bahrs Scrub Road, Bahrs Scrub be renamed Old Bahrs Scrub Road, Bahrs Scrub as outlined in the attached map (Attachment 1). It is proposed to make the effective date 5th April 2021.

5.1 LOGAN WATER CAPITAL WORKS PROGRAM PERFORMANCE MID-YEAR REVIEW 2020-21
REPORT OF: Water Infrastructure Manager
REPORT OVERVIEW
EXECUTIVE SUMMARY The purpose of this report is to provide a status update on delivery progress of the Logan Water Capital Works Program for the second quarter of 2020/2021, and propose a revised program and budget for the current year. Criteria: Direction - It requires Council to make a decision of a strategic nature; or Council has specifically requested it CORPORATE PLAN PRIORITY Conveniently Connected
RECOMMENDATIONS
IT IS RECOMMENDED: That the Logan Water Capital Works Program Performance Mid-Year Review 2020-21, as detailed in the report of the Water Infrastructure Manager dated 25 January 2021, be adopted.
REPORT DETAILS
INTERESTED PARTIES There are no interested parties. PURPOSE OF REPORT/BACKGROUND The approved 2020/2021 Water and Wastewater Capital Works Program is summarised in Table 1, together with year-to-date budget and expenditure to end December 2020. Table 1 Program Approved Budget YTD Budget YTD Expenditure Performance (December 2020) (December 20209) Water - New $9,455,780 2,991,436 $966,615 - Renewals $15,372,433 6,002,616 $8,328,376 Total Water $24,828,213 $8,994,052 $9,294,991 103% Wastewater - New $74,287,866 $20,070,407 $18,617,466
Report Page 1 of 9 Page 22 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
Program Approved Budget YTD Budget YTD Expenditure Performance (December 2020) (December 20209) - Renewals $19,990,005 $9,139,233 $7,410,880 Total Wastewater $94,277,871 $29,209,640 $26,028,346 89% Program Total $119,106,084 $38,203,692 $35,403,784 93%
A number of changes in the first half of the year have influenced the adopted 2020/2021 Water and Wastewater Capital Works Program as follows:
Inclusion of emergent projects where development triggers have occurred earlier than expected, urgent operational need for infrastructure, or opportunity to benefit from an emergent situation; Deferral of scheduled projects where development triggers have not occurred (to avoid premature investment in accordance with QCA requirements);
Delays to scheduled projects due to extended timeframes for statutory approvals and easement acquisitions;
Project scope changes (both increases and decreases); Early commencement or completion of scheduled projects; and
Cost savings due to delivery efficiencies and reduced unit rates. Arising from the above changes, there is a net decrease in the forecast expenditure for the 2020/2021 Water and Wastewater Capital Works Program from $119.11 million to $91.23 million i.e. a decrease of $27.88 million or 23%. These changes have not impacted on the delivery of infrastructure to service growth or maintain levels of service. The management of infrastructure delivery complies with Queensland Competition Authority (QCA) requirements of avoidance of premature investment to achieve prudency and efficiency requirements for investments. SUMMARY OF MAJOR PROJECT VARIANCES The following provides detail on projects in the 2020/2021 Water and Wastewater Capital Works Program where there is major variance in expenditure from approved budgets. A detailed list of all projects on the revised program is included in the Background Papers (Attachment A – DM 14381562).
Report Page 2 of 9 Page 23 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
Water Program: Smart/Digital Metering Project Approved 2020/2021 Budget: $ 1.27 m This project was established to gain knowledge about smart metering technologies to support the decision-making process of Logan Water’s smart metering strategy for the city. The first phase involving installation of 885 devices (442 smart water meters, 443 data loggers) across seven District Metered Areas and 70 schools within the Logan City has been completed. Three different communications technologies were implemented (SigFox, Telstra Nb-IoT, and Taggle’s proprietary radio frequency network). These different devices and communication technologies deployed will enable comparison in terms of devices, communication networks reliability, meter data platforms, management requirements, value to customers and Logan Water, and usability of the data.

5.2 LOGANHOLME AND BEENLEIGH WASTEWATER MANAGEMENT STRATEGY
REPORT OF: Water Infrastructure Manager
REPORT OVERVIEW
EXECUTIVE SUMMARY Following comprehensive options analysis, Logan Water proposes to close the Beenleigh Wastewater Treatment Plant and centralise treatment operations at the Loganholme Wastewater Treatment Plant. This strategy provides the optimum long term financial and environmental outcome for Council. Criteria: Policy development and decision-making - For the benefit of the local government area CORPORATE PLAN PRIORITY Conveniently Connected
RECOMMENDATIONS
IT IS RECOMMENDED: 1. That the proposed strategy to close the Beenleigh Wastewater Treatment Plant and centralise wastewater treatment at the Loganholme Wastewater Treatment Plant, as detailed in the report of the Water Infrastructure Manager dated 25 January 2021, be endorsed. 2. That the Logan Water Capital Works Program be revised to include projects related to the Loganholme and Beenleigh Wastewater Management Strategy.
REPORT DETAILS
INTERESTED PARTIES No interested parties identified. PURPOSE OF REPORT/BACKGROUND Logan Water has undertaken a comprehensive review of the asset condition and performance of the Beenleigh Wastewater Treatment Plant (BWWTP) and concluded that it is a prudent long-term decision to close the BWWTP and divert all wastewater flows from this catchment to Loganholme Wastewater Treatment Plant (LWWTP). Background The BWWTP currently treats around 12 ML of wastewater per day in dry conditions. The treatment plant is at capacity and further augmentation to the facility is problematic due to site constraints. The current flow to the plant includes 5ML/day from the Staplyton catchment within the City of Gold Coast (CoGC). Wastewater flows from Staplyton are treated under a service agreement with CoGC. The service agreement is current to 30 June 2022. Logan Water receives around $3.5m in revenue annually for treating flows from CoGC, which includes around $1m profit. Logan Water is forecasting significant growth in the BWWTP catchment, primarily driven by development in Bahrs Scrub. CoGC is also forecasting significant growth in their Staplyton catchment.
Report Page 1 of 6
Page 52 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
Since the flows into BWWTP are already at the capacity of the plant, Logan Water would not be able to consider extending the use of BWWTP without ceasing the service agreement CoGC and foregoing the associated revenue. Licence Compliance and Growth Logan Water holds an environmental authority (license) to treat up to 15ML of wastewater per day at the BWWTP and is obligated to meet license requirements including pathogen levels, nutrient levels and the concentration of solids in the effluent discharged to the Logan River. Due to the flows into BWWTP being at capacity, Logan Water has struggled to meet its licence requirements for a number of years. Wet weather performance has been particularly poor. Due to repeated failures in the 2017/18 wet season, the State Department of Environment and Science (DES) issued Council with a pre-enforcement notice. At this stage DES has taken no further formal steps regarding enforcement but is aware and supportive of plans to divert flows to the LWWTP. Short term renewals have improved the licence compliance but due to drier than usual conditions last summer, these renewals have not been tested under the additional strain of significant rain events. Asset Condition The condition of component assets within the BWWTP is generally poor. To maintain operations at the site, the forecast annual renewal cost is significant, and these renewals will not increase the treatment capacity of the plant. Negotiation of a new agreement with CoGC Logan Water has been working with the CoGC to develop a financial model, beneficial to both parties, where Logan Water continues to treat flows from the Staplyton catchment. Once finalised, this model will form the basis of a new service agreement. CoGC have determined that it is also to their benefit to continue the current arrangements as it avoids the significant capital investment to take their wastewater flows south to be treated at their Pimpama WWTP. The new model includes COGC paying:
Their proportion of the capital cost for the infrastructure to transfer wastewater between BWWTP and LWWTP. A proportional capital contribution to the Stage 8 upgrade of the LWWTP. A proportional share of the operational cost of both the transfer network and the LWWTP. A proportional share of depreciation expense on existing and new Logan Water assets associated with the transfer and treatment infrastructure. A return on investment relating to existing and new Logan Water assets. An additional 15% ‘risk margin’. At a minimum through this new agreement, Logan Water will secure a $4.75m per year revenue stream. A minimum $3.8m per year will be to recover the CoGC contribution to the capital and operational expenditure and an average $1.m per year for the first 10 years will be profit from return on assets and the 15% risk margin.
Report Page 2 of 6
Page 53 of 57 CITY INFRASTRUCTURE 25 JANUARY 2021
The term of the agreement will be no less than 10 years, with a further extension option of 10 years, giving Logan Water certainty around this revenue stream. There will also be a reset mechanism built into the model to ensure that the agreement stays current with the latest financial performance and variable costs. Once CoGC has committed to this arrangement for servicing their catchment, it is unlikely that they will opt to change due to the prohibitive cost to do so. Gasification Project Logan Water is now well advanced on its biosolids gasification project with the trial phase complete and commencement of the project to build the permanent facility imminent. The original project was based on flows only from the current LWWTP catchment and did not allow for the transfer of flows from the BWWTP. This increase in predicted flows has increased the scale of the project. There was always a staged upgrade for the facility but this step change in projected flows at the commencement of the project has led to what was originally considered to be stage 2 now being what is required when the project is first commissioned. While this will lead to an increase in the capital expenditure of the project, this is offset by the significant reduction in the operational expenditure due to the reduction in biosolids volumes and the related haulage costs prior to land application. Financial Analysis Logan Water has analysed four scenarios using a Net Present Value (NPV) analysis. These scenarios are as follows: 1. Continue with a two-plant scenario, to renew and upgrade BWWTP and LWWTP to meet the growth projections and asset renewal requirements at both sites. Under this option Logan Water cannot provide service to CoGC, foregoing associated profit. 2. Centralise operations at LWWTP using the lowest immediate cost capital solution of additional clarification capacity and related upgrades. Under this option Logan Water cannot provide service to CoGC, foregoing associated profit. 3. Centralise operations at LWWTP using a higher cost capital solution of a new 14ML per day membrane bioreactor (MBR) which has a better whole of life cost. Under this option Logan Water cannot provide service to CoGC, foregoing associated profit. 4. Centralise operations at LWWTP using a new 22ML per day MBR. Under this option Logan Water can service CoGC and generate associated profit. Of the four options considered, the lowest cost, long term option is Option 4 (Centralise at LWWTP with capacity for CoGC) with a forecast 20 year total NPV cost of $265m compared to the Option 1 base case (Maintain a two plant strategy and cease the service agreement with CoGC) with a forecast 20 year total NPV cost of $292m. The summary Net Present Value (NPV) table comparing all assessed options is presented in Table 1.

Other Considerations The BWWTP is more susceptible to future flood events than the LWWTP. In the most recent major flood event, ex-tropical cyclone Debbie March 2017, there was significant damage at the site as shown in Figure 1.
Figure 1 - - Beenleigh Wastewater Treatment Plant March 2017
Future planning for the ceasing of operations at the BWWTP and centralising operations at the LWWTP will require, in addition to new infrastructure provision, planning for matters such as decommissioning of BWWTP infrastructure, rehabilitation of the area; and potential future uses for the BWWTP site. These matters will be incorporated into future planning with updates provided to Council as they progress. ANY PREVIOUS COUNCIL DECISIONS This report was submitted to ELT in September 2020 for endorsement. The 10-year capital works budget submissions have included allowances for these projects.

RISK MANAGEMENT IMPLICATIONS Logan Water considers the planned consolidation of wastewater treatment for the combined Loganholme and Beenleigh catchments at Loganholme WWTP to be the lowest risk option. LEGAL/POLICY Negotiations with the Department of Environment & Science are yet to commence regarding any changes to environmental license requirements. Combined treatment at Loganholme WWTP will result in a net improvement in treatment performance and effluent quality. COMMUNITY AND OTHER CONSULTATION The has been no community consultation on this strategy. CONCLUSION
The Beenleigh WWTP performs poorly, with assets in poor condition, and is not able to be effectively renewed or augmented to cater for growth. The Loganholme WWTP offers the opportunity to transfer flows from Beenleigh to centralise treatment and provide best life cycle cost, providing an improved effluent quality and environmental benefit. The strategy to transfer Beenleigh flows to Loganholme for treatment will require an investment in the order of $120m over the next five years, previously included in the forward works program.
