Port Melbourne to Portsea, Parkdale to Pakenham, have you ever wondered where Melbourne’s water comes from?
Here’s a snapshot of the journey our water goes on to reach the taps of over 1.87 million residential, commercial and industrial customers across Melbourne’s south east.
Melbourne Water
We buy water from our wholesaler, Melbourne Water, who harvests, stores and treats water before it gets to us. For more information, visit the Melbourne Water website
A large proportion of our drinking water comes from protected or uninhabited mountain ash forests high in the Yarra Ranges east of Melbourne, where more than 157,000 hectares have been reserved for the harvesting of water.
Thomson and Upper Yarra Reservoirs
From the uppermost catchments, water flows into the Thomson and Upper Yarra Reservoirs where it may be stored for many years. This is a good thing. Time allows sediment from the forests, washed in by the rain, to settle, providing natural purification.
Silvan and Cardinia Reservoirs
Water from the upper reservoirs is then transferred to Silvan and Cardinia Reservoirs where it’s disinfected to kill bacteria, fluoridated to improve dental health, and corrected for pH.
Sugarloaf Reservoir
Customers around our South Melbourne locality get their water from the Winneke Water Treatment Plant (WTP), located at Sugarloaf Reservoir. This water is harvested from both the Yarra River at Yering Gorge, as well as the Maroondah Aqueduct.
Tarago Reservoir and Winneke Water Treatment Plant
Towns from Bunyip to Lang Lang, the Mornington Peninsula and Cranbourne receive water from the Tarago Reservoir and WTP.
