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's infrastructure delivery
To support growth in the Wilton area, we will soon begin delivery of essential drinking water, recycled water and wastewater infrastructure.
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.
To support this growth, we must deliver essential drinking water, recycled water and wastewater infrastructure.
The full scope of work includes:
- upgrading the Bingara Gorge Water Resource Recovery Facility (WRRF)
- upgrading the Macarthur Water Filtration Plant
- building 8 wastewater pumping stations
- building one drinking water pumping station
- building one recycled water pumping station
- constructing 3 drinking water reservoirs
- constructing one recycled water reservoir
- installing approximately 87 kilometres of pipelines for wastewater, drinking water and recycled water.
To meet the needs of Wilton's gradual growing population, water and wastewater infrastructure will be delivered progressively over 3 stages,
Stage 1: Expected to start mid-2025. This will involve work to service 4,000 dwellings, and deliver water and wastewater services for the initial stages of residential development in South East Wilton, North Wilton and the Bingara Gorge Estate.
The work includes:
a drinking water reservoir, trunk and distribution pipelines
a recycled water reservoir, pumping station and pipelines
- 2 wastewater pumping stations and associated gravity and pressure sewerage pipelines that connect to the Bingara Gorge WRRF
- upgrading the Bingara Gorge WRRF to 2.1 megalitres per day, as well as the recycled water irrigation scheme, to increase its capacity to service development in the area.
Stage 2: In the planning phase. It aims to integrate with the broader servicing plans for the Greater Macarthur region.
Stage 3: Expected to be completed by 2047. We'll provide updates on Stage 3 as the project 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.
