Backflow Prevention

Any connection to Sydney Water’s pipes, including fire services, need to be protected by installing backflow prevention devices. Backflow devices are fitted at the boundary of your property or commercial premises to prevent contaminated water flowing into the public water supply. 

Backflow may happen when the water from your property unintentionally flows backwards into the public water supply and can result in contaminated water being drawn back into the public water supply causing people to become ill from drinking the unclean water.

Sydney Water regulations require for backflow prevention devices to be tested annually and when first installed.
