Water Treatment

Water Treatment

Treating the water before it gets to you is important to make sure it looks, smells and tastes right and meets health standards.  Many water treatment plants have been built in South Australia over the years to improve the quality of available water sources.  The treatment program started with the construction of an iron removal plant at Kingston SE in 1963.

Today there are 43 operational water treatment plants, comprising;

  • Six large conventional water treatment plants serving metropolitan Adelaide.
  • Twenty-three water treatment plants serving country regions and towns. Earlier plants were of conventional design while more recent plants incorporate newer technologies such as ion exchange, membrane filtration and activated carbon adsorption.
  • Ten iron removal plants in the South East
  • Two seawater desalination plants serving Adelaide and Penneshaw and two bore water desalination plant serving Hawker and Leigh Creek

A listing of the locations and types of water treatment plants can be found here .  The treatment process makes sure your water meets the Australian Drinking Water Guidelines (2011). The national guidelines tell us what good, safe drinking water is and how to make sure what we give to you is exactly that.

  • 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.
