Desalinated water is water that has had the salt and impurities removed. We maintain and operate eight desalination plants across the state. Our seawater desalination plants are at Lonsdale in Adelaide ant Penneshaw on Kangaroo Island. We also have desalination plants at Hawker and Leigh Creek in the Flinders Ranges, and four at communities on the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands in the far north of South Australia.

Water produced through a desalination plant doesn't always come from the sea. At Hawker, Leigh Creek and the APY Lands, the desalination plants are used to treat bore water. Read more about the Hawker and Leigh Creek plants here.

Our desalination plants improve security of drinking water supplies for our customers. They give us the ability to supply water regardless of climate impacts and ensure drinking water is available even in times of drought.

You can watch this video to find out more about desalination and water security.

How does desalination work?

Our desalination plants use a technology called reverse osmosis. The process removes up to 99 per cent of the impurities and salt in the water.

Once the impurities (mainly salt) are removed, the water is treated to make sure that it is safe for you to drink.
