Twice a year we run a program of maintenance and cleaning on our water mains known as air scouring.
Air scouring removes the natural build-up of sediment that occurs in water mains.
It involves the use of hydrants to flush compressed air and water through the mains to remove the natural build up of sediment.
Regular cleaning is an important investment in our water networks. It protects the condition and integrity of our water mains so we can provide high quality drinking water.
If the water mains in your area are scheduled for cleaning, you will receive a notification telling you the day, time, and what you need to know.
To facilitate the cleaning program, you may experience an interruption to your water supply (typically around four hours).
While underway, the air scouring process can cause temporary changes to water quality.
The best thing to do is to turn off your 'stop tap' (see diagram below) located at your water meter for the duration of the cleaning process. Once supply has been restored, you can turn your 'stop tap' back on.
If you are unable to turn off your 'stop tap' for any reason off, we recommend you avoid using water during the air scouring.
Please phone us on 1300 363 200 should you have any concerns or if your stop tap is not working.
On the day of your water supply interruption, please store sufficient water for your needs. Water can be stored in containers in your refrigerator, in a sink, or in the bath.
When your water is off your toilet cistern won’t refill after you flush. You may want to fill a bucket with water which can be tipped into your toilet.
If you were unable to turn off your 'stop tap' for any reason you may notice your water looks cloudy after the cleaning is complete.
We recommend you run your taps for a few minutes until the water runs clear.
Your water supply remains safe to drink throughout the water mains cleaning program.
