**Wet weather releases of treated recycled water from Wastewater Treatment Plants**

We are currently releasing treated recycled water from winter storages as detailed below.

Recent rainfall has led to a significant rise in water held in storage at the below wastewater treatment plants and wet weather releases will occur until the storages return to normal operating capacity. We don’t expect that there will be any environmental impacts as the water is released at a rate that ensures it is highly diluted.

We have liaised with relevant catchment management authorities who manage the rivers and have notified the Environment Protection Authority Victoria.

A management plan detailing the discharge amounts and results of the water quality monitoring program is available. Water samples are taken to monitor water quality during and after the release period.

More information is available by calling 1300 659 961 during business hours.

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.

The Federal Government has confirmed it will join the State Government in funding a Horsham Agriculture Smartwater and Integrated Water Management Project.

Each tier of government will provide $4.57-million for a redevelopment that will open the door for a major supply boost of high-quality irrigation water.
