Safe drinking water

Sydney’s water is from natural sources. It’s filtered to the high standards set by the Australian Drinking Water Guidelines.

This ensures it’s safe to drink straight from the tap.

Your drinking water's journey to your tap

Your drinking water is carefully selected from natural sources

Most of Sydney's drinking water comes from rainwater stored in lakes surrounded by some of the most unspoilt, native bushland in the region - including world heritage national parks.
