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 2021-22 water order in June, and is not currently producing water. It is expected to start delivering the 2022-23 water order of 15 gigalitres in September/October 2022.

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.
