Sydney Water’s pressure reduction scheme is intended to reduce the water pressure within the town’s main water supply system to reduce underground pipe breakages and leaks.

This allows Sydney Water to manage the water pressure levels more consistency to ultimately improve the reliability of the water supply system and improve water conservation.

Sydney Water Pressure Management

Areas which are currently affected include various suburbs around Sydney, Illawarra and the Blue Mountains. If your property will be affected by the pressure reduction scheme, Sydney Water will notify you by mail. The letters that you receive from Sydney water are intended to assist them to determine the level of pressure reduction acceptable to maintain a consistent pressure throughout a selected region without causing major system upgrades. The systems that can be affected by a reduction in the town’s main water pressure includes fire hose reels, fire hydrants, fire sprinkler systems and other fire systems connected to Sydney Water’s town main water supply.
