CONFLICT OF INTERESTS

What is a “Conflict of Interests” - A conflict of interests can be of two types:

Pecuniary - an interest that a person has in a matter because of a reasonable likelihood or expectation of appreciable financial gain or loss to the person or another person with whom the person is associated.

Non-pecuniary – a private or personal interest that a Council official has that does not amount to a pecuniary interest as defined in the Code of Conduct for Councillors (eg. A friendship, membership of an association, society or trade union or involvement or interest in an activity and may include an interest of a financial nature).

Remoteness – a person does not have a pecuniary interest in a matter if the interest is so remote or insignificant that it could not reasonably be regarded as likely to influence any decision the person might make in relation to a matter or if the interest is of a kind specified in the Code of Conduct for Councillors.

Who has a Pecuniary Interest? - a person has a pecuniary interest in a matter if the pecuniary interest is the interest of the person, or another person with whom the person is associated (see below).

Relatives, Partners - a person is taken to have a pecuniary interest in a matter if:

·                The person’s spouse or de facto partner or a relative of the person has a pecuniary interest in the matter, or

·                The person, or a nominee, partners or employer of the person, is a member of a company or other body that has a pecuniary interest in the matter.

N.B. “Relative”, in relation to a person means any of the following:

(a)  the parent, grandparent, brother, sister, uncle, aunt, nephew, niece, lineal descends or adopted child of the person or of the person’s spouse;

(b)  the spouse or de facto partners of the person or of a person referred to in paragraph (a)

No Interest in the Matter - however, a person is not taken to have a pecuniary interest in a matter:

·                If the person is unaware of the relevant pecuniary interest of the spouse, de facto partner, relative or company or other body, or

·                Just because the person is a member of, or is employed by, the Council.

·                Just because the person is a member of, or a delegate of the Council to, a company or other body that has a pecuniary interest in the matter provided that the person has no beneficial interest in any shares of the company or body.

Disclosure and participation in meetings

·                A Councillor or a member of a Council Committee who has a pecuniary interest in any matter with which the Council is concerned and who is present at a meeting of the Council or Committee at which the matter is being considered must disclose the nature of the interest to the meeting as soon as practicable.

·                The Councillor or member must not be present at, or in sight of, the meeting of the Council or Committee:

(a)     at any time during which the matter is being considered or discussed by the Council or Committee, or

(b)     at any time during which the Council or Committee is voting on any question in relation to the matter.

No Knowledge - a person does not breach this Clause if the person did not know and could not reasonably be expected to have known that the matter under consideration at the meeting was a matter in which he or she had a pecuniary interest.

Non-pecuniary Interests - Must be disclosed in meetings.

There are a broad range of options available for managing conflicts & the option chosen will depend on an assessment of the circumstances of the matter, the nature of the interest and the significance of the issue being dealt with.  Non-pecuniary conflicts of interests must be dealt with in at least one of the following ways:

·                It may be appropriate that no action be taken where the potential for conflict is minimal.  However, Councillors should consider providing an explanation of why they consider a conflict does not exist.

·                Limit involvement if practical (eg. Participate in discussion but not in decision making or vice-versa).  Care needs to be taken when exercising this option.

·                Remove the source of the conflict (eg. Relinquishing or divesting the personal interest that creates the conflict)

·                Have no involvement by absenting yourself from and not taking part in any debate or voting on the issue as of the provisions in the Code of Conduct (particularly if you have a significant non-pecuniary interest)

Committee members are reminded that they should declare and manage all conflicts of interest in respect of any matter on this Agenda, in accordance with the Code of Conduct.

RECORDING OF VOTING ON PLANNING MATTERS

In accordance with the Committee Recommendations, Council resolved the following:

 

 

24-421

Resolved that Council does not adopt the following Recommendation:

Report No. 4.1 Mullumbimby Water Supply Strategy Public Consultation Report

Committee Recommendation 4.1.1

That Council: 

1.    Publicly thanks the community for its participation in making more than 433 Your-Say submissions during June 2024 on Mullumbimby's future water supply; 

2.    Acknowledges that 89% of 411 valid Your-Say respondents oppose abandoning the Wilsons Creek source (Lavertys Gap), while 6% are neutral and 5% support; 

3.    Notes that Hydrosphere's report "Mullumbimby Water Supply Strategy" of December 2021 does not investigate Option 2 (adding off-stream storage and retaining the Wilsons Creek source) to the extent suggested in Council's Resolution 23-120 and that it assesses Option 3 (Rous only) without Dunoon Dam which is now included in Rous's forward water source planning; 

4.    Notes the following extract from the North Coast Enabling Regional Adaptation, North Coast Region Report (NSW Office of Environment and Heritage, 2019) which states on page 15: 

     “Under a transformed system for infrastructure [,] water systems are smaller, localised and decentralised with multiple redundancies providing tailored and integrated solutions” 

5.    Proceeds with the investigations previously outlined in Parts 7 and 8 of Resolution 23-120 with some additions in 8b and 8c, namely:

6.    Investigates a strategy for Mullumbimby’s long term water supply based on the following concept:

a) Lavertys Gap as the source during flows in excess of environmental requirements;

b) water stored off-stream between the source and Mullumbimby;

c) water treated at a new location between the storage and Mullumbimby;

d) water delivered to Mullumbimby and possibly beyond; and

e) maximising demand management, including the harvesting of roof water.

          7.      Includes in this investigation: 

a) the topography of the terrain between Lavertys Gap and Mullumbimby, to identify potential dam sites;

b) the hydrology of Wilsons Creek and its capacity to supply, including

                   (i) seasonality,

                   (ii) establishing environmental flows for future EPA licensing;

c) the impact of climate change on supply and on demand (using up-to-date CC data and methodologies in the pilot phase for local water supply through DPE, and applied in Regional Water Strategies);

d) infrastructure needs including offtake, storage, treatment and linkages to the town’s reservoirs;

e) environmental assessments for the creation and operation of that infrastructure, including greenhouse gas emissions;

f)  assessment of the weir at Lavertys Gap including

                   (i) structural integrity;

                   (ii) means of creating fish passage; and

                   (iii) how this proposal enhances its heritage and preservation; and

g) economic assessment.

8.       Notes the successful upgrade to Kyogle’s water supply which included off stream storage and creation of fish passage on the existing weir in the Richmond River.

9.    Supports Council consulting with landowners of properties currently supplied from the pressure line between the Water Treatment Plant at Lavertys Gap and the reservoir near Azalea Street, by:

a) Listening to their wishes, and

b) Considering outcomes including a reticulation pipeline returning from Azalea Street reservoir to those properties.

Summary:

This report provides an overview of Council’s Integrated Planning and Reporting Framework and invites discussion on priority areas for inclusion in Council’s delivery program.

  

 

 

RECOMMENDATION:

That the Water and Sewer Advisory Committee:

1.      Notes Council’s Integrated Planning and Reporting Framework;

2.      Notes Council’s priorities as identified by Councillors for the 2025 – 2029 and Delivery Program

 


 

Background to Integrative Planning and Reporting (IP&R)

The Integrated Planning and Reporting Framework in NSW requires all councils to adopt a suite of strategic plans. These long-term plans provide transparency and make it possible for Council to plan in a manner which ensures that community needs and priorities are responded to well into the future. Council also has a suite of strategies, plans and policies which help inform operations and decision making, and these policies are adhered to in alignment with the Integrated Planning and Reporting Framework.

The central IP&R documents are outlined in more detail:

10 Year Community Strategic Plan

Leading the Council’s planning hierarchy, the Community Strategic Plan (CSP) captures the community’s vision, aspirations, and expectations for the future. It identifies key social, economic, and environmental priorities and long term strategies to achieve these goals over the next 10 years.

The CSP outlines the vision, community objectives and supporting strategies which will guide Council’s long-term decision making. Robust engagement with the community about their desires and expectations has guided the long-term future planning to meet the needs and aspirations of the community.

10 Year Resourcing Strategy

The resourcing strategy addresses the sustainable long term financial, asset management, and workforce planning requirements. This is the point where Council assists the community by sorting out who is responsible for what, in terms of the issues identified in the Community Strategic Plan.

4 Year Delivery Program

The delivery program translates the community strategic plan goals into actions. It is Council’s commitment to the community, outlining what it intends to do toward achieving the goals of the community strategic plan during its term of office. The Delivery Program is the single point of reference for all principal activities undertaken by Council. All plans, projects, activities, and funding allocations must be directly linked to the four-year delivery program.

Annual Operational Plan

The Delivery Program is supported by an annual Operational Plan which details the individual projects and activities that will be undertaken each year to achieve the commitments of the Delivery Program. The Operational Plan is supported by a detailed budget and a statement of revenue policy, which also sets the fees and charges for that year.

Advisory Committee Input into IP&R

The key IP&R documents described in the Background section are in the process of review as is the requirement following a local government election.

The current Community Strategic Plan (CSP) 2032 has been reviewed and the next iteration, the CSP 2035, was placed on public exhibition at the 28 November 2024 Ordinary Council meeting with submissions open until 9 February 2025. The revised CSP will be presented back to Council for adoption in May 2025. The draft can be found on Council’s website at www.byron.nsw.gov.au/communityplan.

Adjacent to this, the Delivery Program 2025 – 2029 and Operational Plan 2025/26 are being developed. Both documents will be presented to Council in May 2025 and placed on public exhibition for public feedback.

The four-year priorities recently identified by Councillors for inclusion in the Delivery Plan 2025-2029 that relate to the Committee include:

·    Water Supply

·    Wastewater Management

·    Storm-water

·    Water Sensitive Urban Design

·    Water Security

Report

Purpose

This report provides a high-level project design for the delivery of evidence-based recommendations for Council to decide on a future water supply strategy for Mullumbimby.

The project in question responds to Council Resolution 24-477 (see Attachment 1)

Staff request the Committee to provide feedback and advice for ensuring the project design is fit-for-purpose.

Note: Council’s Executive Management team have transferred responsibility for the delivery of this project to the Assets & Major Projects Team.

Background

Mullumbimby’s water supply is sourced from the Lavertys Gap weir, situated in the upper reaches of Wilson’s Creek.  The weir feeds the Mullumbimby Water Treatment Plant (WTP), which then supplies potable water to the town’s water network. 

Various elements of this scheme were commissioned between the 1920s and 1940s.

It also included a small hydroelectric plant, but was decommissioned in 1989.

Due to its location, condition and design, the Lavertys Gap weir / Mullumbimby WTP scheme is vulnerable to droughts and extreme weather events, and in the face of Mullumbimby’s future development estimates, it is predicted the scheme will not be able to meet Mullumbimby’s water demand beyond 2028.

In situations when the Lavertys Gap weir / Mullumbimby WTP scheme fails (e.g. during droughts or wet weather) Council can operate a supplementary water source through the Rous Emergency Water Supply Line.  This scheme connects Mullumbimby to the Rous regional water network, with current capacity to cover approximately half of the town’s water demand.  The emergency line was built in response to the 2002-2003 drought. Following the 2022 floods, Council secured State Government funding to upgrade the emergency’s line capacity to be able to cover all of Mullumbimby’s reticulated water demand. 

In recognition of these issues, since 2019 Council staff have produced a substantial body of work aimed at informing a long-term water supply strategy for Mullumbimby (see Attachment 2). Various water supply options were assessed, with the resulting recommendation being to permanently connect Mullumbimby to the Rous regional water supply via the existing emergency supply line. This recommendation was adopted by Council in August 2024 (Res. 24-411, Attachment 3).

However, in October 2024, Council decided to defer the decision for an additional two years to allow for further investigations and community consultation while addressing the ongoing risks to the Lavertys Gap weir / Mullumbimby WTP scheme (Res. 24-477, Attachment 1).  This latest Resolution is the catalyst for the project described in this report.

Project design

Staff are undergoing project design to enable an evidence-based and transparent decision-making process to secure long-term water security for Mullumbimby.  Lessons learnt are being distilled from the previous round of work and the deliberation process that resulted on Council’s Resolution 24-477 (Attachment 1).  Staff are also concerned with the ongoing structural, performance and compliance shortfalls of the Lavertys Gap weir / Mullumbimby WTP scheme, which are further compounded by the rising risk of extreme weather events and Council’s financial constraints and capital investment priorities across the Shire’s water supply systems.

Thus, considering the complexity of the above issues, it is of paramount importance that Council staff and decision makers agree on why this project is needed, what it is aiming to achieve, and how it will do so, as well as recognising the constraints and risks that influence it.

The sections below articulate a proposed project design to facilitate this agreement.

Project conceptual framework

Figure 1 below presents the proposed project at a conceptual level. It establishes the desired impact (i.e. guarantee sustainable, long-term water supply security for the town of Mullumbimby), and works backwards to describe the project outcomes, outputs, actions and resources that will support that impact. Project drivers and contextual issues are also described.

 

Figure 1 – Project conceptual framework

Project assumptions

-     Previous investigations (see Attachment 2) will be reviewed and used as a key input for this project.

 

-     Off-stream storage option: while this option was already explored in previous investigations, additional comment and high-level/desktop assessments will be provided regarding:

 

§ possible sites for an off-stream storage

§ hydrology, water quality and catchment impacts

§ environmental flows considerations

§ considerations regarding landholder consultation and land acquisition

 

-     Hybrid water supply option: this new option assumes the combined operation of the Lavertys Gap water source and the Rous regional water supply (via the upgraded Rous Emergency Supply Line), offering enhanced water security and operational flexibility.  This may involve the downsizing and/or relocation of the Mullumbimby WTP to reduce risks associated with extreme weather, treatment performance and regulatory compliance.

 

-     Mullumbimby’s future water demand estimates will be revised and updated in alignment with the latest growth forecasts (i.e. Byron Shire Residential Strategy 2041).

 

-     Item 4.c. of Res. 24-477 (Attachment 1) requests that the reinstatement of hydroelectric facility be explored as part of this investigation.  High-level commentary can and will be provided around this issue.  It is expected however that given the site’s heritage significance (and related constraints), water licence considerations, governance arrangements, and Council’s service provision and capital investment priorities, this option will not feature in this study.

 

-     Decision making framework: The process for shortlisting options and ultimately recommending a water supply solution to Council will be multi-staged:

 

§ Stage 1: Options shortlisting through Multi-Criteria Analysis (MCA) based on community-designed objectives, criteria and criteria-weightings. Community input will be facilitated via a series of workshops.

§ Stage 2: Shortlisted options will then go through a Benefit-Cost Assessment (BCA) to assess their economic viability (i.e. benefit/cost ratio). The assessment will follow BCA guidelines from NSW Treasury.

§ Stage 3: Net-Present Value (NPV) of shortlisted options over a 30-year timeframe will provide the basis for understanding the financial impact on Council, and ultimately, the ratepayer.

 

Other metrics may be defined to assist Councillors on their final decision, and could include estimated rate increases, dollars per kilolitre of water supplied ($/kL), etc.

Project risks

Staff considers important risks impacting the delivery of this project to be clearly defined and understood across stakeholders.  While a comprehensive risk assessment is proposed to be done early on the project timeline, an initial description of some key project risks is provided below.  Staff hopes to use this as a springboard to further unveil project risks in collaboration with the WSAC, and support the upcoming risk assessment process.

-     The capital costs of some options to be investigated may exceed Council's and the community's capacity to fund it (via rate increases). This risks the long-term condition of water provision assets and levels of service to the community.

-     Unpredictable weather events, the high-risk nature of Wilsons Creek catchment, and the end-of-life condition of the Lavertys Gap weir / Mullumbimby WTP scheme hinder Council’s capacity to maintain water security and comply with relevant regulation until a final decision is made and implemented.

-     Recent revised growth forecasts for Mullumbimby are likely to increase future water demand estimates, changing water supply options’ capacity modelling.

-     The State Heritage listing of Mullumbimby Hydro-electric Power Station Complex. This includes the weir but not the treatment plant. There will be additional approvals required to modify or upgrade the weir.

-     Community’s willingness to pay for proposed options is yet to be understood.

-     Misinformation / disinformation in the community throughout this project may impact efforts to drive evidence-based decision making.

Project interdependencies

Achieving a decision on a long-term water supply strategy for Mullumbimby and safeguarding short-term water provision may be influenced or constrained by other Council activities/projects, including:

 

-     Rous Emergency Water Supply Line upgrade project: This is currently ongoing, with completion expected by September 2025.  Regardless of what long-term water supply strategy Council decides on, completion of this upgrade is critical to enable that strategy, either as the main water supply moving forward, or as the redundancy required to allow for the implementation of other long-term solutions. It will also offer interim water supply security in case the Lavertys Gap weir / Mullumbimby WTP scheme fails before a long-term strategy is adopted.

 

-     Negotiation of Level of Service Agreement (LSA) with Rous: As requested in item 3 of Res. 24-477 (Attachment 1), Council’s executive team, with support from Utilities staff, are in negotiations with Rous to facilitate a reduction of the emergency water supply volumetric charges.  This important to help reduce the financial impact on Council if Lavertys Gap weir / Mullumbimby WTP fails and/or reliance on the Rous Emergency Supply Line increases in the short term.

 

-     Lavertys Gap weir condition assessment, monitoring and repairs project: Council’s Utilities Department, with the support of NSW Public Works, is undertaking actions to address bank erosion issues that put at risk the weir’s structural integrity, and consequently, its storage capacity.  The key focus is on condition monitoring until final remediation works can be done. These are only possible once the upgraded Rous Emergency Water Supply Line is operational. Wet weather events can hinder these efforts.

 

-     Mullumbimby WTP short-term improvements: Following advice from NSW Health, Council staff are investigating operational controls and treatment process upgrades to manage non-compliance risks at Mullumbimby WTP.  These risks relate to the high-risk nature of the Wilson’s Creek catchment and the design and end-of-life condition of the WTP, and might trigger boil water alerts if advised by the regulator.

 

-     Securing water supply for Wilson Creek residents: There are 13 properties in Wilsons Creek directly connected to the Mullumbimby WTP trunk main.  These connections are not compliant with Council’s current Water Supply Operations Standards and land zoning rules, but it is understood this is a legacy issue going back to the establishment of the Mullumbimby WTP.  The properties have become reliant on the potable water supply for rural water security, with a high level of water consumption.

 

It is expected that potable supply to the above-mentioned properties will need to continue (item 6, Res. 24-411, Attachment 3). In the short term, supply from the WTP is at risk due to the issues described in the above sections, and Council will need to find alternative water sources if required (e.g. trucking water to the WTP’s clear water tank).  In the long-term, if Council decides to favour the Rous supply, upgrades to water conveyance and storage systems will be required to enable supply to the Wilsons Creek residents.

Condition of the System Summary

The treatment wetland cells were commissioned as part of the 2006 capital works program and components of the system are now in need of replacement and renewal in order to ensure that the wetland system provides the required polishing function for treated effluent from the Byron Bay STP.

The wetland cell inlets in particular have reached the end of their functional life and are now not providing even distribution of effluent flow across the top of the cells. In a number of locations water depths do not support the establishment of dense healthy aquatic macrophyte vegetation. There is also Acid Sulphate Soils underlying Cell D.

Weed management requirements on the site are significant and require sustained effort to but some areas of improvement are evident particularly Cells D, E and H.

Since the bushfire the operation of the 24ha regeneration area has not been feasible. Much of the infrastructure was completely destroyed.

Condition of Cell H has improved with Salvinia control with more bird activity and Black Necked Storks observed on two occasions.

Migratory bird activity also appears to have improved with Latham’s snipe detected in 2024. Grass Owls were not detected on the site in survey undertaken in 2024.

ASSET MAINTENANCE MANAGEMENT

Continuous Improvement Actions

Recent Improvements:

1.      Property water meters have already been brought into the system and reactive maintenance tasks are routinely logged against these.  The geographical location of the meters could not be discerned as part of the GIS upload and therefore meters are currently, in general, located in the centre of each lot.  We are currently undergoing a process of relocating each meter to the correct location in line with information held in the Water Billing system. Currently:

a.      Mullumbimby, Bangalow, and Brunswick Heads are complete and service lines have been generated.

b.      Suffolk Park is at approximately 35% completion and will be included in the system in the coming weeks.

2.      Following recent update to the Assetic platform, changes have been made to the Planned Maintenance programming and the Asset catalogue to create separate Work Groups for operational teams. Previously all teams were within one Water and Sewer Work Group, which cluttered workspaces and required complex filtering to avoid seeing all work for all teams. Moving forward, all PM tasks will be generated within their appropriate Work Groups. Team leaders and supervising staff who create work orders for reactive work have been notified of this change. 

3.      Because of the live nature of current reporting integrations between Assetic and Power BI, there is not currently a way to look back on the state of the system as it was in any given month in the past. The IT Team have created a series of history tables that will be appended at the end of every month, essentially creating easily reportable snapshots of the Assetic system to track KPIs, as seen below

Next Steps:

1.      Weekly meetings with team leaders were suspended over the Christmas/New Year break and have resumed to drive further improvements to the Assetic System.

2.      With the ongoing effort to digitise and properly catalogue plans and important asset-related documents, the team will soon be uploading more of these documents to Assetic to be easily accessible to field staff when needed.

ASSET MAINTENANCE STATUS

Planned Maintenance – Progress against Program

Overall, Utilities planned maintenance in February is 89.6% tasks completed by due date against a target of 80%. The current long-term average of tasks completed by due date is 86.7%.

Planned versus Reactive Maintenance

The figure below shows the comparative maintenance hours for each team between planned and reactive maintenance. Reactive maintenance has taken 67.0% of all hours spent working on assets for the last 12 months.

Gravity Sewer Mains Remediation

Based on previous condition assessments of the gravity sewer main network, Willow and Sparrow identified mains that required remediation works to prolong their use and/or to fix acute defects.  The remediation scope included the installation of patch liners, excavation and repair, and CCTV survey.  This package of works was awarded to Subsurface Pipe Solutions to a value of $132,950 plus GST.  Work has commenced and is currently running on schedule. There has been some variation in scope due to previously unknown site and asset conditions which has resulted in lowering the overall budget whilst maintaining the desired outcomes. This project is nearing completion.

Gravity Sewer Condition Assessments

The condition assessment of gravity sewer mains and maintenance holes was awarded to Willow and Sparrow (maintenance holes) and Subsurface Mapping Solutions (mains).  The Maintenance hole condition assessments are underway.  The CCTV mains contract was awarded to Subsurface Mapping Solutions and work is scheduled to be completed by June 30.  The sewer catchments that fall within this scope are across Bangalow, Suffolk Park, and Ocean Shores.  The indicative budgetary limit of ~$320,000 will cover the costs for both CCTV assessments and MH visual assessments. Condition assessment reports for mains and maintenance holes will be completed once all data has been gathered.
