We've been inspecting the wastewater system in Bingara Gorge to help determine the location and cause of increased wastewater flows in the network during and after wet weather events. Repairs are being completed to improve the gravity wastewater system assets. We're also reviewing our inspection results and planning upgrades and improvements on the pressure sewerage system equipment. We will provide residents with details about our plans to complete any repairs to improve the pressure sewerage system before work starts. We've been working with the golf course to ensure that recycled water is used effectively as an environmentally sustainable water supply for irrigation.

Wilton Integrated Servicing Program
To support growth in the Wilton area, we are delivering new drinking water, recycled water and wastewater infrastructure to ensure a resilient, reliable water supply and protect the environment in the Wilton area
About this project
The Wilton area is expected to see significant population growth, requiring substantial water and wastewater infrastructure to support up to 15,000 homes by 2047.
The Wilton Integrated Servicing Program is Sydney Water’s plan to ensure the right infrastructure is delivered at the right time to support this growth.
Stage 1 of the Program will be built by our deliver partner, Acciona, over the next three years. It will include the construction of the following new infrastructure, beginning July 2025.
- Upgrade of the existing Wilton Water Resource Recovery Facility
- 2 wastewater pumping stations
- 1 recycled water pumping station
- 1 drinking water reservoir
- 1 recycled water reservoir
- Approximately 26 km of wastewater, drinking water and recycled water pipelines
Planning for stage 2 and 3 is underway and we will keep the community informed as this work progresses.
Benefits
- connecting into existing infrastructure to provide value for money for customers
- 8.1 megalitres per day water supply to the Wilton area
- 15,000 new dwellings serviced by 2047
- 2 megalitres per day of recycled water available for non-drinking purposes such as flushing toilets and irrigation
- reducing environmental impacts, particularly in koala habitats and threatened vegetation communities.
Impacts
There may be interruptions to the drinking water supply at worksites while we set up new water infrastructure. We'll inform the community before any disruptions happen. These interruptions will follow our usual procedures.

FAQs
We purchased the Bingara Gorge facility as part of our commitment to provide high quality services to the area. The projects we're delivering are to ensure the drinking water, recycled water and wastewater systems meet our safety and environmental compliance obligations.
A Review of Environmental Factors (REF) assesses the potential environmental issues associated with the construction and operation of a project. It proposes mitigation measures to eliminate or manage potential impacts, and whether the project should be permitted, by considering all factors that have or could have an impact on the environment. We're committed to reducing environmental impacts on the community and the environment, particularly in koala habitats and threatened vegetation communities.
