Western Murray Irrigation manages water quality mainly through scouring

Non-Potable Water

Western Murray Irrigation pumps water directly from the Murray River.

The water is not treated and is not fit for human consumption (non-potable).

Generally it can be used for stock and garden use, however, when toxic blue-green algae are present, this water may not be suitable for human use or stock.

The water quality of the Murray River can vary by month and year and is affected by factors including:

  • Temperature
  • Turbidity
  • Nutrients
  • Algae
  • Salinity
Blue Green Algae

Blue-green algae are the only group of algae known to be toxic in freshwaters. WaterNSW maintains algal alerts here https://www.waternsw.com.au/water-quality/algae#stay

Water Maintenance

Western Murray Irrigation manages water quality generally through scouring, but occasionally problems persist with the natural build up of water animals and plants.

There are a number of actions customers can take including a regularly maintained on-farm irrigation system and regular cleaning of the outlet filter. However, if problems persist contact Western Murray Irrigation for assistance.

Managing blocked filters from Bryozoans

Western Murray Irrigation is undertaking a water quality treatment program to manage bryozoans which can cause blocked pipes and filters. The program will involve the addition of a low dose hydrogen peroxide at the pump stations in all three irrigation areas commencing in 2019. This follows research and consultation including feedback from customers regarding blocked filters.

Hydrogen peroxide used in this way is safe and effective in the management of bryozoans and will not impact irrigation or stock & garden customers during application.

The treatment will NOT make the water potable and customers should continue to use water for irrigation and stock & garden only.
