We keep local residents informed about projects in their area.

We're continually maintaining the quality of our drinking water and making improvements to provide a reliable water supply.

We assess the condition of our large water pipes to get information about which pipes need to be repaired or replaced before they break.

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.

Silt and debris management

Northwest Sydney Land and Waterways

  • Location - Beaumont Hills, Glenwood, Kellyville, Rouse Hill and Stanhope Gardens
  • Timeframe – ongoing


We’ve developed a strategic stormwater management plan in Northwest Sydney, which is known as the Rouse Hill development area. This includes regenerating bushland on stormwater drainage land in Beaumont Hills, Glenwood, Kellyville, Rouse Hill and Stanhope Gardens.

Our strategy will help reduce flood risk to properties and restore local creeks and waterways. It will also improve water quality entering the Hawkesbury-Nepean River. 

Learn more about our Northwest Sydney Land and Waterways in Beaumont Hills, Glenwood, Kellyville, Rouse Hill and Stanhope Gardens. 

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 growth areas. They work in consultation with relevant local councils, NSW Government agencies and developers.
