Our drinking water comes from the natural environment.

All water comes from nature. But, it’s how it gets to us that can have a big impact on the environment. We take care by using the urban water cycle and mostly the power of gravity, drawing water from many sources, so that we have a reliable and sustainable water supply. Not just today, but for generations to come. WaterNSW protects our main drinking water catchments. They use their expertise to monitor and select the best quality source water so it can be filtered by Sydney Water.

Our main source of drinking water comes from rainwater collected in the stunning Lake Burragorang, which sits behind Warragamba Dam. This supplies 80% of our water. The lake was formed when the dam was built on the Warragamba River. The name comes from the Aboriginal words Warra and Gamba, meaning water running over rocks. It’s a testament to the beauty of this natural area.

Protected from most human activities for over 70 years, the Warragamba Special Area, surrounds Lake Burragorang. This helps protect water quality by providing a buffer of pristine bushland. It includes national parks like Blue Mountains, Kanangra Boyd, Nattai and Thirlmere Lakes, and state conservation areas and nature reserves.
