How much desalinated water is supplied?

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.

The plant completed the 2020–21 water order in May, and is not currently producing water. It is scheduled to begin delivering the 2021–22 water order of 125 gigalitres from July 1 2021.

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.
