Desalinated water is water that has had the salt and impurities removed. At SA Water we maintain four desalination plants at Penneshaw on Kangaroo Island, Hawker and Leigh Creek in the Flinders Ranges and the largest one in the state at Port Stanvac.

Water produced through a desalination plant doesn't necessarily come from the sea. At Hawker and Leigh Creek, the need for a desalination plant arose because local residents consider it too salty to drink. Read more about the Hawker and Leigh Creek plants here.

Our desalination plants improve access to drinking water. They give us the ability to supply water regardless of climate impacts. The plants ensure drinking water is still 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% 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.
