Kemps Creek Dual Pressure Mains
Sydney Water is investing in infrastructure to support the future population and economic growth of Western Sydney. This includes the construction of 6.8km of dual wastewater pipes (known as pressure mains) from the sewage pumping station being constructed at Gurner Avenue, Austral to the Upper South Creek Advanced Water Recycling Centre (AWRC) being constructed at Kemps Creek.
The Kemps Creek Dual Pressure Mains (KCPM) project will improve wastewater services in the South West Growth Area (SWGA), one of the NSW State Government’s three designated growth areas in South West Sydney. This area will see substantial growth over the coming years, increasing from 2,300 dwellings in 2022 to approximately 38,000 dwellings by 2056.
It will do this by transferring wastewater that is collected from homes and businesses in Austral, Leppington North, parts of Leppington, parts of Catherine Fields North, Rossmore, and Kemps Creek (known as the Kemps Creek catchment area) to the AWRC to be treated there.
The AWRC is Sydney Water’s largest infrastructure investment in Western Sydney. It will be a sophisticated wastewater treatment and resource recovery centre that will produce recycled water, renewable energy and bio-resources. It will use reverse osmosis - the same technology used by the desalination plant - to treat water to a high-quality.
When completed in early 2026, the AWRC and associated pipelines will deliver sustainable wastewater services and high-quality recycled water to support a cooler, greener Western Parkland City.
Key benefits for the local community include:
- efficient and cost-effective wastewater services
- high-quality, recycled water for a range of non-drinking reuses
- protecting waterway health and aquatic ecosystems via environmental flows
- enhanced biodiversity by greening Western Sydney with recycled water
- energy generation from recycled organic waste and solar
- biosolids for use as fertilisers in agriculture.

Sydney Water and our delivery partner, Quickway, are finalising the design and preparing to start construction of the Kemps Creek Dual Pressure Mains.
From July you will see Quickway crews in the area as they finalise investigation activities, bring in equipment and establish site compounds.
The two new pipelines will be installed along Floribunda Road, Pratten Street and Cross Street. Traffic management will be in place in these areas. Please drive safely and keep an eye out for our workers while they deliver this essential infrastructure.

Archaeological salvage activities

As part of Sydney Waters environmental assessment for the Kemps Creek Dual Pressure Main project, a Potential Archaeological Deposit was identified along the pipeline’s alignment, near Tavistock Road.
Before construction commences in this area, we will undertake the appropriate archaeological salvage work, to recover any Aboriginal cultural heritage items that may be in that location before construction disturbs them.
Sydney Water has engaged an independent consultant to complete this activity and they will work with local First Nations representatives to do so.
