River salinity

River salinity

Salt is a natural feature of the Murray Darling Basin. Because of the flat land, low rainfall and high rate of evaporation, the salt has become concentrated within the soil and groundwater.

What are the current salinity levels?

We monitor the River Murray and provide salinity reports on a daily basis.

What effect does salinity have?

Different salt levels have a different impact on people, industries and on your pipes. In industry, high levels of dissolved salts can cause corrosion, scale and poor steam quality. It can also increase the need for chemicals to be used in water treatment.

Salt Interception Schemes

Salt interception schemes divert saline groundwater and drainage water before it enters rivers. In most cases, a bore and pump system pumps the groundwater to a salt management basin some distance from the river.

At SA Water, we manage these schemes on behalf of the Murray-Darling Basin Authority in South Australia. There are other salt interception schemes interstate. Since 1988, these schemes have prevented approximately half a million tonnes of salt from reaching the River Murray each year.

  • 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.
