Backflow is an ongoing threat to the quality of Water Corporation's drinking water supply is the flow of water backwards from a customer's property through their property's water service connection (fire services included).

This water may be contaminated by the activities carried out at the property, and may cause death, health problems or an inconvenience to persons ingesting or using the water. Click here for more information.

A reversal of the normal direction of water flow in a water supply plumbing system. It occurs when the water delivery main is at a lower pressure than the internal plumbing system (back-siphonage). Back-siphonage can occur when there is a burst or ruptured main, or due to excessive demand during firefighting operations or other periods of high demand. Backflow can also occur if a pump (such as a bore pump) is cross connected to the internal water plumbing system, and is pumping bore water at a higher pressure than the water mains pressure (backpressure).

If a property's drinking water supply is inadvertently interconnected with a source of pollution, either through a cross connection or simply a hose submerged in a container of liquid, then these pollutants could enter the water supply when there is an overpressure on the private property side or a sudden drop in water mains pressure.
