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.

For more information about Silvan's location, check out this Google Map.
