Greater Western Water is one of two metropolitan Melbourne's water businesses owned by the Victorian Government. Greater Western Water was created by the integration of City West Water and Western Water on 1 July 2021.
Greater Western Water provides drinking water, sewerage, trade waste and recycled water services to customers in Melbourne’s central business district, inner and western suburbs, as well as the north-west area of Melbourne.
Our service areas includes Brimbank, Hobsons Bay, Maribyrnong, Melbourne (north of the Yarra River), Moonee Valley, Wyndham, Yarra, Melton, and Hume and the Macedon Ranges.
Each year we supply over 93 billion litres of drinking water to our customers and transfer a large majority of the sewage and trade waste we collect to Melbourne Water’s Western Treatment Plant in Werribee. The remainder is treated at one of our eight Water Treatment Plants.
In addition to our core business, we have many programs and policies in place to help us achieve our vision to be a truly sustainable water business.
Our business is managed by an Executive Leadership Team, which consists of the Managing Director, four General Managers, a Chief Transformation Officer, a Chief People Officer, a Senior Executive Advisor - GWW Integration, a Chief Financial Officer and a Chief Information Officer.
The Executive Leadership Team oversees policy implementations, the day-to-day management of our people, and the delivery of services to our customers. Learn more about our leadership team
Our Board of Directors are appointed by our shareholder, the Victorian State Government. Directors provide the Board with a broad range of skills to the business, including management, engineering, financial, legal and environmental expertise. Learn more about our board of directors
