Cardinia Reservoir dam upgrade

We’re planning to complete a dam safety upgrade to Cardinia Reservoir in the summer of 2024/25, as part of our proactive management of our water supply reservoirs. The upgrade will protect and prolong the life of one of Victoria’s most pristine water catchments, helping us to continue supplying world-class drinking water to Melburnians.
