Our role

At WaterNSW we are custodians of the state’s water, a vital natural resource.  It is our responsibility to capture, store and deliver water, when and where it matters.

We operate the state’s dams in Greater Sydney and regional NSW, using our knowledge of nature, science and engineering. We then supply that water ready for distribution – for the environment, agriculture, industry and the community.

With 41 major dams and hundreds of waterways across the state, we play a vital role at the source of the state’s water, delivering two thirds of all water used in NSW.  The water we supply supports more than 8 million people across NSW – it is used by regional towns, farmers, the environment and customers, like Sydney Water.

Every day we operate our assets and manage water responsibly to meet the needs of our customers and communities now, and into the future.

WaterNSW has a number of main functions:
