Most of the stormwater pipes and channels in the Sydney metropolitan area are the responsibility of local councils. We own some of the large stormwater pipes, channels and drains.

We work closely with local councils and other agencies to manage Sydney’s stormwater flows.

Our wastewater and water recycling plants treat wastewater to a high level so it can be safely re-used.

We provide recycled water for homes and businesses, industry, parks, farms, golf courses and playing fields and for river health.

This helps save drinking water and secures our water supply for Sydney’s growing population.

Hoxton Park Recycled Water Scheme

  • Location - Edmondson Park, Elizabeth Hills, Freemans Ridge, Ingleburn Gardens, Len Water Industrial Estate, Middleton Grange, Panorama Estate, Park Bridge Estate and Yarrunga Industrial Estates
  • Timeframe - we plan to start operating this scheme when there are enough properties built and connected to our wastewater and recycled water pipes
     
We expect that recycled water could start being produced at the water recycling plant in 2019-20. We'll review the number of property connections and forecasted growth in 2017 and prepare a plan to bring the scheme into operation.

We'll be providing high quality recycled water to parts of new residential suburbs and industrial areas in Sydney's south-west.

Learn more about the Hoxton Park Recycled Water Scheme.

We're planning and building new water and wastewater infrastructure to enable development in the growth areas. This infrastructure is essential to allow development as outlined in the NSW Government’s A Plan For Growing Sydney.

The Department of Planning and Environment is responsible for rezoning land and the sequence of land release in priority growth areas. They work in consultation with relevant local councils, NSW Government agencies and developers.
