Wastewater & mains water flooding

Call 13 13 75 immediately if you have wastewater or mains water overflowing anywhere on, or near, your property or any damage is being caused. This line is attended 24 hours a day, 7 days a week.

Protecting our mains water and wastewater systems

We are all responsible for the health of our water and wastewater systems, and we can all take some simple steps to help keep them working properly: 

  • Putting the wrong things down toilets and sinks can cause sewer blockages and overflows – which can sometimes cause real damage and devastation to your home, as well as to our wastewater system. Find out what not to flush or wash down the drain
  • Keep your outside overflow relief gully clear. This is designed to release any wastewater away from the home in the event of a sewer blockage. See Your responsibilities.
  • Choose your trees and shrubs carefully, as they can cause problems below ground. See Selecting the right tree
