Silvan Reservoir is the heart of the water transfer system, supplying water to most parts of Melbourne’s metropolitan area.
Introducing Silvan Reservoir
Silvan's dam was completed in 1932. It is an earthfill embankment with reinforced concrete core wall.
Silvan receives 'inflows' from the Thomson, Upper Yarra and O’Shannassy reservoirs and other small tributaries to the Yarra River.
Cardinia and Greenvale reservoirs are supplied by the Silvan system.
These sources are supplied to Melbourne’s water retailers unfiltered because of the high quality of water drawn from the protected catchments and large storages.
