Reclaimed 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 reclaimed water across the region to participating customers.
Reclaimed water treatment
Our reclaimed water is treated to a Class C level 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
Reclaimed water is often stored in the winter and then used during the dry summer and autumn months when other water sources are scarce.
Reclaimed water releases
GWMWater is currently discharging Class C recycled water that meets with EPA requirements for use of reclaimed water from the Horsham Wastewater Treatment Plant to the Wimmera River and Ararat Water Treatment Plant to the Hopkins River in the coming weeks.
Recent rainfall has led to a significant rise in recycled water held in storage at the plant and wet weather discharges will occur. The discharge is not expected to create any adverse environmental impacts.
A management plan detailing proposed discharges and a water quality monitoring program have been developed and results are detailed in the documents below:
