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
We are currently discharging Class C recycled (reclaimed) water that meets with EPA requirements for use of reclaimed water from:
- Ararat Wastewater Treatment Plant to the Hopkins River during August and September 2017.
- Horsham Wastewater Treatment Plant to the Wimmera River during August and September 2017.
- St Arnaud Wastewater Treatment Plant to the St Arnaud Creek during August and September 2017.
- Willaura Wastewater Treatment Plant to Cockajemmy Lake during September and October 2017.
- Stawell Wastewater Treatment Plant to Pleasant Creek during September and October 2017.
- Halls Gap Wastewater Treatment Plant to Back Creek during September and October 2017.
Recent rainfall has led to a significant rise in recycled water held in storage at the wastewater treatment plant/s and wet weather discharges will occur.
The discharge is not expected to create any adverse environmental impacts. A water quality monitoring program and a management plan have been developed and results are detailed in the documents below:
