Desalination data

The Victorian Desalination Plant is integral to securing Melbourne’s water supply – building a buffer in our water storages to support a growing population. Get an overview of how much desalinated water has been added to our water storages daily.

How much desalinated water is supplied?

Victorian Desalination Plant
Desalinated water flowing into Cardinia Reservoir, where it enters Melbourne’s water supply network.

The Victorian Desalination Plant can deliver up to 150 billion litres of high-quality drinking water a year. That’s one-third of Melbourne’s needs, or around 60,000 Olympic swimming pools.

21 September 2022: Melbourne’s water supply is in its best position in more than a quarter of a century. Based on these storage levels, projected weather patterns including a third straight summer of predicted La Niña events, demand, and the risk of spill, Melbourne Water has provided independent advice to the Minister for Water recommending the Victorian Government cease the remainder of the 2022/23 desalination order. This advice was accepted and the desalination order has been halted.

So how much water has the desalination plant contributed to Melbourne’s supplies? Let’s break it down – see how much was delivered in the past 30 days.
