About recycled water

Recycled water is treated wastewater available for reuse from our wastewater treatment plants. It's an important resource for GWMWater and the region. It has many benefits, such as:

  • helping to maintain community resources such as sports ovals, race courses and golf courses
  • encouraging regional growth by supporting community recreational spaces and local industry, such as vineyards
  • reducing the need for drinking water or raw water in irrigation
  • providing potable water substitution options
  • reducing environmental impacts from traditional river discharges

Ten of our 28 wastewater treatment plants are currently supplying recycled water across the region to participating customers.


Recycled water treatment

Our recycled water is treated to meet fit for purpose requirements according to EPA Victoria's guidelines. Under the guidelines, this water is used for:

  • urban areas that have restricted public access during irrigation
  • agricultural uses for vineyards
  • agricultural uses for grazing or as fodder for livestock
  • industrial uses for systems with no potential worker exposure

Recycled water is often stored in the winter and then used during the dry summer and autumn months when other water sources are scarce.
