What Melbourne Water does

Melbourne Water Corporation is a Victorian State Government-owned water utility established under the Water Act 1989, headquartered in Melbourne Docklands. The organisation manages the full urban water cycle for Greater Melbourne, including bulk water supply, waterways, sewerage, drainage, and floodplain management, serving approximately 4.6 million residents (projected to reach nearly 8 million by 2050). Its core physical infrastructure comprises 10 major reservoirs with combined capacity of 1,812 GL, the Western Treatment Plant at Werribee and Eastern Treatment Plant at Braeside, 1,400 km of regional drains, 400+ km of sewers, 25,000 km of waterways, and more than 200 rainfall and river-level monitoring sites. The technology stack includes a cloud-based spatial digital twin framework built with University of Melbourne on open geospatial standards (OGC API, CityGML, IFC), PostgreSQL/PostGIS, Apache Kafka streaming, and React-CesiumJS interfaces, enabling flood modelling, stormwater capacity assessment, and building envelope compliance analytics. Melbourne Water also operates biogas-to-energy generation at treatment plants, hydroelectric assets, and is targeting 100% renewable electricity by end of 2025 and net zero emissions by 2030.

Melbourne Water operates as a regulated monopoly under oversight of the Essential Services Commission, generating revenue through bulk water supply to four retail water corporations (Yarra Valley Water, South East Water, Greater Western Water, City West Water), waterways and drainage charges, sewerage services, developer/construction fees, and recycled and desalinated water sales. It is the largest producer of Class A recycled water in Australia and confirmed a 150 GL desalinated water order for 2026-27 to replenish supply via Cardinia Reservoir. The customer base extends beyond retail corporations to local councils (Glen Eira, Merri-bek, Moonee Valley, Banyule, Brimbank, Hobsons Bay), agricultural users, developers, and Traditional Owner organisations (DJAARA, Taungurung Land and Waters Council, First People of the Millewa-Mallee Aboriginal Corporation). Pricing for 2026-27 includes a 7% increase in Melbourne (~$73) and 5% in regional Victoria (~$68), reflecting significant ongoing capital investment driven by population growth, climate change adaptation, and water security needs.
