South Australian town to get new desalination plant
South Australia's water minister, Ian Hunter, announced on 1 May 2013 that a brackish-water desalination plant to deliver improved water quality to the town of Hawker, in the Flinders Ranges 100km north of Port Augusta, had been approved for construction.A final report to the state House of Assembly on the same day said that the reverse-osmosis plant would provide 500 m³/d with a target salinity of <600 mg/L.
Water supplied to Hawker is sourced from groundwater characterised by high total dissolved solids and hardness. At present, the water is treated by an iron-removal plant before being delivered to a concrete surface tank and then gravity-fed to the township.
Installation of a new 1,000 m³ treated water storage tank will be part of the new project, which will cost Aus$ 5.75 million (US$ 5.84 million).
