Great Western Water

“Greater Western Water (GWW) was formed on 1 July 2021, bringing together Western Water (WW) and City West Water (CWW) to meet the demands of our region and deliver reliable, affordable and secure water services, now and for decades to come.

GWW is proud to serve one of the fastest-growing regions in Australia. We provide drinking water, recycled water, sewerage and trade waste services to more than 550,000 residential customers and 46,000 business customers.

Our service area covers 3,700 square kilometres, stretching from Melbourne’s CBD, inner and north-western suburbs through the Melton and Sunbury growth corridors to Bacchus Marsh and the Macedon Ranges.

The local government areas of Brimbank, Hobsons Bay, Maribyrnong, Melton, Moonee Valley, Wyndham and Yarra are within our service area, as well as parts of the local government areas of Hume, Macedon Ranges, Melbourne and Moorabool.

We operate in Bunurong, Wurundjeri, Wadawurrung, Dja Dja Wurrung and Taungurung Country. The Maribyrnong and Werribee Rivers are the major waterways in our region and the source of some of the water we supply to customers.” – Great Western Water Annual Report 2021-2022 (read complete annual report via the GWW website here)
