Sewering Coastal Villages
Last updated: 9 October 2025
Bellingen Shire Council, in partnership with the NSW Government, is currently delivering the Sewering Coastal Villages Scheme, a major infrastructure project aimed at providing a modern, sustainable sewerage service to our coastal communities. The project is being delivered in three phases:
- Phase One: Upgrade of the Urunga Sewerage Treatment Plant – Works Near Completion
- Phase Two: Connection of Mylestom and Parts of Raleigh
- Stage 1 - Construction of sewer rising mains and pump stations – Works underway due for completion in December 2025
- Stage 2 – Construction of low pressure sewer reticulation network and property connections – Works planned to commence in August 2025 until late 2026
- Phase Three: A future, currently unfunded phase to service Repton and the Raleigh Industrial Area.
This project addresses longstanding issues caused by failing septic systems, including odour, overflow events, groundwater contamination, and public health risks. These systems have also contributed to repeated closures of the Bellinger and Kalang Rivers due to faecal contamination, which affects oyster farming, water quality, and local businesses.
The area impacted by the Project can be viewed in the interactive map below.

Why is Council upgrading the Sewer Systems?
Council is focused on providing the most sustainable sewerage service to benefit and meet the needs of the community. The proposed modern centralised sewerage scheme will have numerous benefits for the entire area, including a positive environmental impact by reducing onsite system leakage and eliminating odour and water quality issues.
Many residences are served by septic tanks equipped with absorption trenches or pump-out systems. These systems risk groundwater contamination and associated public health impacts via overflow events and ineffective treatment.
The Bellinger and Kalang Rivers have been closed on numerous occasions due to repeated instances of faecal contamination. These closures, which have impacted on public health and the health of our rivers, wetlands, oyster farms and local businesses, can largely be attributed to failing septic tanks within the project area.
How much will this cost?
The Sewering Coastal Villages project is funded thanks to more than $11 million from the NSW Government and over $27 million from Bellingen Shire Council against its long term financial plan.
Individual residential landowners will not have to pay for the new Low Pressure Sewer System as resolved in the 2019 November Council Meeting.
If landowners request an alternative placement of the pressure sewer system for a non-technical reason, they will be required to pay the difference in installation costs. Council will discuss with individual Landowners and agree prior to undertaking the works.
Once sewerage services are connected, there will be an annual charge for landowners in accordance with Council's Fees & Charges.
In 2025/26, the sewerage charge is $1233 per annum for residential properties with a standard connection. Landowners will also need to pay the cost of electricity to run the domestic sewer pump, this is estimated to be between $52 and $65 per year.
Commercial properties that use less than 20 kilolitres of water per day will be charged 25% of the connection cost. Commercial properties that use more than 20 kilolitres of water per day will be charged 100% of the connection cost.
When will works start?
Construction of Phase 1 Urunga Sewer Treatment Plant Upgrade is underway and due for completion in mid-2025.
Construction of Phase 2 has commenced, with work on rising mains and pump stations beginning in May 2025.
Following property inspections to determine the location of each new low pressure system in late 2024, installation works for individual connections will commence in late 2025.
What is a Low Pressure Sewer System?
Low pressure sewer systems convey wastewater from your home to the regional wastewater treatment facility. Unlike gravity connection, they use a small pump station located at each house to move wastewater through the transmission system.
The Low Pressure Sewer System would be installed next to the existing septic tank and connected to the street. The power supply for the pump would be connected to the residential meter box. The existing septic tank would be decommissioned but not removed, owners may remove the decommissioned septic tanks if desired after the completion of the project, at their own cost.

Frequently Asked Questions
Is my property part of the sewerage scheme?
Council has created an interactive map to show what properties are impacted.
INTERACTIVE MAP
Is it compulsory that my property is connected to Council's pressure sewerage system?
Yes, all properties identified in the scheme areas would be required to connect to sewerage within 18 months of sewerage being available. Council has power under Section 124 of the Local Government Act to order properties to connect to sewer within 75 metres of reticulated sewerage.
What are the costs for residential property owners?
Council will cover the cost of the connecting pipe work if the new grinder pump is to be located adjacent to the decommissioned septic system.
Note: this infers that the property owner will be required to pay for pipe work in situations where they choose to have the new grinder pump not located adjacent to the decommissioned septic system. This is not a common scenario as most property owners are happy to have the new grinder pump located close to the decommissioned septic system.
Will there be ongoing operating costs to property owners?
Yes, once sewerage services are connected, there will be an annual charge for landowners in accordance with Council's Fees & Charges.
In 2025/26, the sewerage charge is $1233 per annum for residential properties with a standard connection. Landowners will also need to pay the cost of electricity to run the domestic sewer pump, this is estimated to be between $52 and $65 per year.
Once the sewer is connected, landowners will not have the cost of pumping out the septic tank or paying septic inspection fees. Pump out costs depend on the number of people using the septic system and cost between $300 - $400 per time. The septic inspection fee is $158 per time.
If Council has to repair the pressure sewer system, what will it cost me?
Council will maintain all sewer infrastructure from the street to the storage tank and pump. The maintenance cost of pressure sewer systems is included in the annual sewer connected charge so there is no cost to the property owner for maintenance. Landowners will be provided with an operations manuals detailing items that should not be put down the sewer. If the cause of the problem is the property has put material down the sewer which they shouldn't such as wipes, nappies or oil, Council may charge the property the cost of the repairs.
What should I do if I want to replace my existing septic system before the project begins?
You should hold off or complete minimal repairs to keep the system operating until February 2025. However, if the system has completely failed you must replace it at your cost.
What will happen with the existing septic system?
As part of the connection works, the existing septic tanks will be decommissioned and bypassed. The new pressure sewer system will connect directly to the property’s existing sanitary drainage. The tanks will be pumped out, treated with lime, and holes will be drilled in the base to allow drainage.
Removal or filling of the tanks will be the responsibility of the property owner after completion of the works. Property owners who wish to retain their tanks for future use must advise Council or the contractor before decommissioning, as the tanks will not be drilled in that case.
What will happen if Council sees unapproved structures on properties when the sewerage system is being installed?
Council will offer an amnesty on unapproved structures/buildings to land owners in the Scheme’s footprint. Council will work closely with owners to provide guidance and advice on what applications need to be made to Council in order to have these structures/buildings assessed. Each application will be assessed on its merits in accordance with the relevant planning legislation.
Is the sewer scheme going to open up the coastal villages for further development?
No, Council is connecting the sewer to the coastal villages because of the public health and environmental benefits.
Overall there is limited potential for growth in the sewer system areas. The system is only being sized to accommodate a limited number of extra connections consisting of identified infill, vacant blocks and a minimal number of town house developments.
Once the sewer system is in place the capacity of the system will not be able to be increased in the future to respond to new development. Rural land that has already been zoned for development will be accommodated by the sewer system but there will be no capacity within the system for any new land releases.
The land on the corner of Keevers Drive and Perry’s Road in Repton is currently zoned for residential purposes. While the land is yet to be developed, there is the potential for over 200 new residential lots to be accommodated on the land (subject to a detailed subdivision design). This kind of subdivision is referred to ‘greenfield development’ The sewer system will be able to service this land if it is ever developed.
In January 2020 Council approved the Bellingen Shire Local Housing Strategy. This 20 year strategy outlines Council’s approach to future growth across the Shire. The Strategy commits to new growth within existing towns through well designed infill rather than releasing further rural land for subdivisions. It includes infill growth goals for different locations across the Shire over 20 years. Overall Council anticipates that half of the Shires growth over the next 20 years will come from well- designed infill with the remainder coming from subdivisions on land that has already been zoned for development.
The infill growth goal for Mylestom, Repton and Raleigh is 56 dwellings over 20 years.
Significant growth is expected in Urunga over the same period. There is land in Urunga currently zoned for development that has the capacity for up to 1,000 extra dwellings.
