Each year we carry out routine cleaning of water main networks to ensure we continue to deliver safe drinking water and high-quality services to our customers, and maintain our supply network infrastructure.

In 2022 financial year, Water Mains Cleaning was carried out in Spring Gully, Epsom and Castlemaine. Water Mains Cleaning has finished until next spring

Notifications of mains cleaning in your area

Planned Water Mains Cleaning will be listed on this page. There are currently no planned water mains cleaning works.

If your area is scheduled to be cleaned, you will receive a notification telling you what day and time water mains cleaning will be started in your street. Notifications are hand-delivered seven days before works begin.

Preparing for an interruption

During the works, the quality of the water in the network could temporarily be reduced. To avoid this water entering your home, we recommend not using the water during the Water Mains Cleaning window, usually two hours.

The most effective way to stop water from entering your home is to turn off your stop tap (see diagram below). When water has been restored, you can turn your stop tap back on.

If you are unable to turn your stop tap 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.

Storing water

Prior to the time listed above we advise you to store sufficient water for your day’s needs. For convenience, water can be stored in containers in your refrigerator or in the bath. When your water is off, your toilet cistern won’t refill after you flush so you may want to fill a bucket with water which can be tipped into your toilet.

Water quality

If you were unable to turn off your stop tap you may notice your water looks cloudy. We recommend you run your taps for about 15 minutes or until the water becomes clear again.

Safe to drink

Your water supply remains safe to drink throughout the water mains cleaning program.
