Bulk water supply
WaterNSW supplies more than two-thirds of water used in NSW.
Bulk supply of raw water across NSW
We manage the bulk supply of raw water for our customers and for the benefit of communities and the environment.
WaterNSW manages the bulk supply of raw water to the Greater Sydney region and regional NSW. In fact, we supply more than two-thirds of the water used across NSW. The raw water we supply is either treated by our customers; that is councils and water utilities, for supply into the drinking water network, or is used in its raw state for farming and irrigation purposes.
In regional NSW, bulk water is moved using the state's river systems and our network of dams and weirs. When a customer orders a large volume of water, our water delivery team releases the right amount of water at the right time to fulfil the order. Learn more about river operations.
In Greater Sydney, bulk water is transported using a network of rivers, pipes and canals. The majority of bulk water is supplied to Prospect Water Filtration Plant, operated by Sydney Water, which supplies approximately 80% of Sydney's drinking water.
