Water Discolouration

Water discolouration can occur for various reasons with the most common cause being a disturbance of natural sediment build-up within the mains.

The most common reasons you may experience water discolouration include:

  • Accidential break in the main - this usually occurs at the most inconvenient time.
  • Population boost - during times of high-volume water usage, especially over busy holiday periods when our population increases considerably. 

To help maintain our systems, Shoalhaven Water regularly undertakes a scheduled program of water mains flushing across the city. This can also be known as scouring. The program helps to remove sediment build-up that can accumulate normally within the water supply system.

How are the mains flushed?

The flushing process consists of cleaning or ‘scouring’ the interior of the water distribution mains by sending a rapid flow of water through the mains. By flushing the water under high release pressure through the mains, the build-up of sediment will be dislodged.

Shoalhaven Water will notify residents prior to any planned scouring occurring. 

What do I do if I experience discoloured water?

Consult with neighbours and if the problem does not appear to be isolated to an individual house contact us immediately so that we can investigate the problem. 

If you have experienced discoloured water, try running your outside tap for 1-5 minutes until the water clears. By running your front garden tap you will prevent the discoloured water from entering your internal lines. If you have noticed discoloured water inside the house, start with the front tap and run it until the water clears, then run your backyard tap for a few minutes to help clear the lines inside the house. 

Is discoloured water safe to drink?

Whilst discoloured water is generally safe to drink, it is unpalatable and is not recommended fro drinking. Shoalhaven Water can arrange for alternative drinking water supplies on request.
