Desalinated water

What is desalinated water?

Desalinated water is drinking water that is produced from sea water. In Melbourne, our desalinated water is produced at the Victorian Desalination Plant in Wonthaggi.

Like all drinking water, desalination water meets the requirements of the Australian Drinking Water Guidelines, Victorian Safe Drinking Water Act and the World Health Organisation guidelines.

Water from the Victorian Desalination Plant is some of the best in the world to complement the high quality of water that Melburnians enjoy. More information is available through the Department of Environment, Land, Water and Planning’s website.

When will we receive desalinated water?

Since 2016, 76 billion litres of desalinated water have boosted our supplies. In March 2019, the Minister for Water announced an order of 125 billion litres of desalinated water for the 2019–-20 financial year.

Desalinated water helps build a buffer of water in our storages to secure supply in event of severe drought. Combining desalinated water with efficiency measures and investing in recycled water and storm water harvesting increases our resilience against drought by maintaining storages at a higher level.

When will the next order be?

In April each year, based on advice from South East Water, the other Melbourne retailers and Melbourne Water, the Minister of Water announces whether an order will be placed or not in the coming financial year.

The decision is based on how much is needed in the next year to maintain water security, expected rainfall, current storage levels and cost to customers.

What will desalinated water taste like and look like?

Desalinated water will be mixed with existing water storages and undergo the same treatment process - so there’ll be no difference to the taste or appearance of water that comes out of your tap.
