Is Sydney Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Sydney tap water is safe to drink for most people. It is treated and routinely monitored under New South Wales health regulations and the Australian Drinking Water Guidelines.
The water supply is disinfected to control harmful bacteria and other microorganisms. A mild chlorine taste or smell can occur, but it is generally harmless; older household plumbing may affect water quality at the tap.

Source of Water in Sydney, Australia
Sydney’s tap water comes mainly from surface water stored in dams and reservoirs across the Greater Sydney catchment system. Warragamba Dam is the primary source, supplying most of the city’s drinking water.
Other sources include the Upper Nepean, Woronora, Blue Mountains and Shoalhaven systems. The water is treated and tested before being distributed through Sydney Water’s network.
Sydney Drinking Fountains
Public drinking fountains in Sydney are generally connected to treated mains water and are safe to use under normal conditions. The water is regulated to meet Australian drinking water quality standards.
Avoid using a fountain that is visibly damaged, dirty, or marked as out of service, and let the water run briefly before drinking. Do not use it during a boil-water or other public health advisory.
