Silvan Reservoir

Silvan Reservoir is the heart of the transfer system, supplying most parts of Melbourne’s metropolitan area. Silvan also stores water from the Upper Yarra system for transfer to Cardinia. The dam was completed in 1932 and is an earthfill embankment with reinforced concrete core wall.

Silvan Water Treatment Plant is operated and maintained safely by Melbourne Water under a Major Hazard Facility licence from WorkSafe Victoria. Water is disinfected to destroy residual micro-organisms. Further information can be obtained by contacting your local library (Eastern Regional Libraries, Yarra Plenty Regional Library) or Melbourne Water directly.
