This review is relevant to water customers living in and around the Melbourne metropolitan area

Melbourne Water provides wholesale water supply and sewage management services to retail water corporations that we also regulate. These retail water corporations are City West Water, South East Water, Yarra Valley Water, Western Water, Barwon Water, South Gippsland Water and Westernport Water.

Melbourne Water also provides drainage and waterways services in and around Melbourne.

Key facts from our final decision

Our final decision approved revenue of $7.9 billion over the five year period starting 1 July 2021. As a result, prices will fall adding to price reductions proposed by Melbourne Water. This translates to a average bill reduction of around $20 in 2021-22 year for a typical residential household.

Melburnians will continue to receive high quality drinking water, safe treatment and disposal of sewage, and new investment in waterways and drainage. Melbourne Water will continue to reduce its environmental footprint and respond to climate change.

Melbourne Water proposes a five-year regulatory period starting 1 July 2021. Our final decision approves maximum prices for a five-year regulatory period.
