Pipe cleaning is done using a technique known as air scouring, which involves injecting filtered pressurised air through the pipe to remove any naturally occurring sediment.
Impacts
While air scouring is happening, you will be without water for approximately 2 hours.
Affected customers will be directly notified up to 7 days prior of work being done in their area.
A schedule will also be published on our Planned Works page (when available).
If possible, customers will be asked to turn their stop tap off at the water meter, prior to the time of commencement listed on the interruption notice.
When the water is back on
Customers may notice that the water is a little cloudy or milky after air scouring. This is caused by small pressurised air bubbles. This will resolve over time and is safe to drink.
