What's happening?

We're building 4 water treatment plants in Mount Magnet, Cue, Sandstone and Meekatharra to improve water quality in the Murchison region.

The water treatment plants will use a desalination process called electrodialysis reversal (EDR). EDR technology has been successfully used in regional towns across Australia to improve water quality conditions, reduce nitrate levels and convert over 90% of the treated water into drinking water. It is currently used at the Wiluna and Yalgoo water treatment plants in the Murchison region.

Where is this happening?

Mount Magnet, Cue, Sandstone and Meekatharra.

Why is this work taking place?

Due to underlying rock conditions, water in these towns may be affected by salinity, hardness, nitrates and other undesirable qualities in the groundwater. The new water treatment plants will improve water quality by reducing salinity, nitrates and hardness.

When is this happening?

In late 2019, we started building the first plant in Mount Magnet and expect all plants to be operational in 2022.

Current status

Mount Magnet

  • Work site – Genga Pump Station
  • November 2020 – this plant is now operational and in the optimisation period
  • Work involved building two evaporation ponds, electrodialysis reversal unit and hybrid power system.

Cue

  • Work sites – Cue Water Treatment Plant and Cue Tank Farm
  • September 2021 - this plant is now operational and in the optimisation period
  • Work involved building two evaporation ponds, new water storage tank, electrodialysis reversal unit and hybrid power system.

Sandstone

  • Work sites – Sandstone Treatment Plant and Griffith Street
  • November 2021 - this plant is now operational and in the optimisation period
  • Work involved building two evaporation ponds and electrodialysis reversal unit at the water treatment plant site and building two water storage tanks and booster pump station at the Griffith Street site.

Meekatharra

  • Work site – Sherwood Pump Station
  • Work completed – built two evaporation ponds; installed solar power at water treatment plant site and new crossover on Great Northern Highway
  • Upcoming work -  build, transfer and test electrodialysis reversal unit
  • Expected completion – mid 2022

How will this impact the community?

Most work is completed at our existing treatment plant and tank farm sites outside of town. Residents may notice more vehicles and contractors in the area however construction noise will be minimal.

  • Cue, Meekatharra, Mount Magnet, New Norcia, Sandstone, Yalgoo, Laverton, Leonora, Menzies, Nabawa and Wiluna in the Murchison and Goldfields regions have naturally occurring underlying rock conditions that affect the quality of drinking water sourced from local bores. Water in these towns may be affected by salinity, hardness, magnesium, nitrates and silica in the groundwater.

  • It is acknowledged due to these conditions, the water may have an undesirable taste for some people, make it difficult to lather soap and leave brown crystalline deposits on surfaces when evaporated.

  • This water is safe for everyone, except bottle-fed infants under the age of 3 months who are provided with bottled water from the local nursing post.

  • Water Corporation has already installed water treatment units at Wiluna, Leonora and Yalgoo to reduce the levels of nitrates in water supplies.
