Water sources

Geelong is supplied by the catchments on the upper Barwon and Moorabool rivers and – during drought – by two underground aquifers.

The Barwon River system and Otways Ranges catchment typically supplies around 80% of greater Geelong’s water, with the balance from catchments on the Moorabool River system in the Brisbane Ranges.

Supplies in the Colac-Otway region are drawn from five separate sources, all located in forested Otway catchments.

Lorne, Aireys Inlet / Fairhaven, and Apollo Bay / Skenes Creek / Marengo have their own discrete water supply systems.
