2018 Year in Review; Highlights


  • Planning for the Future - Aqwest started its largest capital works project of the last decade, the construction of a new water treatment plant in Bunbury’s eastern suburb of Glen Iris. The plant will have
    the potential to supply almost half of Bunbury’s average
    water consumption demand. Due to the impacts of climate
    change, the risk of increasing salinity levels threatens water
    quality. Water extraction and treatment at Glen Iris will
    replace current water abstraction from the sensitive coastal
    freshwater-seawater interface area. Benefits will also be
    obtained from lower production costs and by reducing
    the need for the expensive refurbishment of Aqwest’s
    current coastal treatment plants, which will ultimately be
  • Water Quality - Aqwest complied with the Australian Drinking Water Guidelines and achieved 100% microbiological compliance.
  • Water Conservation - Aqwest’s residential customers have continued to reduce their water use against a target of <280 kL.
    Water consumption dropped from 261 kL in 2016
    to 247 kL in 2017 and to 245 kL in 2018.

  • Customer Satisfaction - Aqwest is committed to providing sustainable, high quality drinking water that consistently meets or
    exceeds its customers’ expectations. Every year,
    Aqwest invites its customers to give their feedback
    in a survey. The latest survey showed that Aqwest
    had maintained its overall satisfaction rating, with a
    result of 85.3 per cent.
