Aboriginal acknowledgement

Melbourne Water respectfully acknowledges Aboriginal people as Australia’s First Peoples and the local Traditional Owners as the original custodians of the land and water on which it relies and operates. It pays its deepest respects to their Elders past, present and future.

Melbourne Water acknowledges the continued cultural, social and spiritual connections Aboriginal people have with the lands and waters, and recognises and values that the Traditional Owner groups have cared for and protected them for thousands of generations.

In the spirit of reconciliation, Melbourne Water remains committed to working in partnership with local Traditional Owners to ensure their ongoing contribution to the future of the water management landscape, while maintaining their cultural and spiritual connections.

Drinking water supply

Melbourne Water supplies, treats and transfers drinking water to Melbourne’s three retail water corporations, Greater Western Water, South East Water and Yarra Valley Water. Other wholesale water customers are the Victorian Environmental Water Holder, urban regional businesses including Barwon Water and Gippsland Water, and the rural water supplier Southern Rural Water.

Melbourne’s water supply comprises 10 storage reservoirs across Melbourne and its surrounds with a total capacity of 1,812 billion litres. Water in these storages is sourced mostly from protected catchments in the Yarra Ranges, forested areas located in national parks, and state forests.

More information about Melbourne Water’s supply system can be found on their website.

Sewage and recycled water

Melbourne Water treats and disposes of approximately 90 per cent of the sewage generated in greater Melbourne at their two treatment sites, the Western Treatment Plant (WTP) at Werribee and the Eastern Treatment Plant (ETP) at Bangholme.

Melbourne Water’s sewerage transfer system consists of over 400 kilometres of sewers, eight sewage pumping stations and 12 air treatment facilities moving large volumes of sewage across the city.

WTP and ETP also produce recycled water which is used for agriculture and other non-drinking purposes taking pressure off Melbourne’s drinking water supplies.

More information about Melbourne Water’s sewerage system can be found on their website.

Waterways and drainage

Melbourne Water is responsible for ensuring that we continue to care for the health and vitality of waterways throughout the Port Phillip and Westernport region. Melbourne Water monitors and provides targeted maintenance for approximately 25,000 kilometers of rivers and creeks, and more than 700 stormwater treatment systems and wetlands.

Melbourne Water is also responsible for the regional management of floodplain, drainage and stormwater services across the Port Philip and Westernport region. To keep communities safe and minimise the impact of flooding, they determine building and development criteria, provide flooding advice and work with their partners to make sure Melbourne prepares for future flooding events.
