Drinking water quality

We are committed to provide drinking water that consistently meets Australian Drinking Water Guidelines and is both safe and pleasant to drink for nearly 2 million Western Australians.

Delivering water of the highest quality

We run an extensive drinking water quality monitoring program to confirm the safety of the water we provide to our customers. We take more than 75,000 water samples each year from water sources, treatment plants and pipe networks which supply our customers, and have in excess of 300,000 individual analyses performed by our contracted analytical laboratories.

For our drinking water catchments, we proactively manage and protect drinking water catchments by undertaking catchment surveillance and inspections, by-law enforcement, water sampling, and providing land use planning advice.

Further information on health related and aesthetic water quality variables for each locality of WA, as well as commonly asked questions can be found in our water quality publications.
