Desalination

Desalination

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.

  • Water Quality
  • SA Water customers in Goolwa and surrounding areas, including Goolwa Beach, Goolwa South, Goolwa North and Hindmarsh Island may currently be experiencing discoloured or milky water coming out of their taps.

    This water remains safe to drink.

    During recent planned maintenance in the area, some existing sediment in the local water supply network has been stirred up, resulting in the discoloured water.

    We are working hard to resolve the issue, and we are flushing out the discoloured water. Given the size of the water network in the area, this may take some time. At this stage, we are hoping water supply will return to normal by Friday afternoon.

    We will continue to monitor the situation, and provide updates on our website and Facebook page.

    For further information or any questions, please contact us on 1300 SA WATER.
