Sydney's tap water

Some of the world's best

Sydney Water has helped make Greater Sydney a liveable city for over 130 years. We’re passionate and proud of our role in shaping the lifestyle of Sydney, the Blue Mountains and the Illawarra for generations to come by providing high-quality water for all.

Sydney has some of the best drinking water in the world - that’s because we are dedicated to making sure we always meet the Australian Drinking Water Guidelines. Sydney Water works to ensure that Australians in Greater Sydney have access to high-quality tap water that is safe and tastes great.

Sydney water supply

To ensure a reliable and sustainable water supply for generations to come, we take care in sourcing our tap water. Our main drinking water catchments are protected and monitored by WaterNSW before being filtered by Sydney Water.

Most of our drinking water is sourced from rainwater, which is collected in lakes and rivers in NSW that are surrounded by some of the most unspoilt native bushland in the region, including World Heritage National Parks. 80% of our water is collected in Lake Burragorang and is protected by the Warragamba Special Area.

Our desalination plant is part of the New South Wales Government’s plan to ensure a secure and affordable water supply system for Greater Sydney. Desalination is one of the ways we can meet water demand when we’re faced with a prolonged drought.
