How are mains flushed?

The flushing process consists of cleaning the interior of the water mains by sending a rapid flow of water through the main. This is known as scouring. By flushing the water under higher release pressure through the mains, the build-up of sediment will be dislodged. Some slight discolouration of the water supply may occur after mains flushing in the immediate area, but this will quickly disperse after running a tap for a short period of time.

Council will notify residents of any planned scouring occurring. If you experience dirty, or discoloured water after a scheduled clean, try running the outside tap for 1 to 5 minutes until the water clears.
