Ultraviolet Light (UV) Disinfection

Ultraviolet Light (UV) Disinfection

Ultraviolet light is used to disinfect water in some water treatment plants. Exposure to adequate doses of UV light renders bacteria, viruses and protozoa non-pathogenic to humans. In the UV disinfection process, the water passes through reactors with sufficient UV lamps to deliver the required UV dose. The required UV dose is dependent on certain water quality factors such as clarity, dissolved compounds and microorganisms present. A listing of the water treatment plants that employ UV disinfection can be found here .

To find out which method of disinfection your water treatment plant uses, visit our In your area: whats in your Water? page.

  • 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.
