The Liberal National Government will implement the next tranche of its pressure management program in parts of Maddington, Kenwick, Martin, Cannington, East Cannington, Wilson, Bentley, Queens Park, Welshpool and the remaining parts of Beckenham not affected in the previous trial.
"Pressure management reduces excessive high pressure in water pipes and is proven to minimise leaks and breaks and lower water use," Water Minister Mia Davies said.
"About 260 million litres of water is being saved each year in Rossmoyne, Shelley, Waterford and parts of Beckenham, where pressure management works are already complete."
The new round of suburbs has been assessed and prioritised by the Water Corporation based on existing water pressure, the historical frequency of leaks and breaks in the pipe network and overall water use volumes. These suburbs receive average pressures in the range of 42 to 66 metres head. This will be gradually reduced to 35 metres head, which is more than double the required minimum standard.
"Pressure reductions will be implemented gradually in stages starting later this year. This will result in more consistent pressure and greatly minimise leaks and breaks caused from excessively high water pressure," the Minister said.
"The corporation has a community liaison team which will work closely with residents and businesses to keep them informed before any pressure reductions take place.
"Advice from the irrigation industry has confirmed correctly installed and maintained irrigation systems operate effectively at the pressures that customers will receive."
The 10-year pressure management program forms part of the State Government's water loss management strategy and is expected to save more than 10 billion litres of water each year once fully implemented.

The corporation began implementing the pressure management program in 2014, following a successful trial in Rossmoyne, Shelley and Waterford between 2008 and 2010. The first area targeted as part of the program was Beckenham
About 70 million litres of water each year will be saved in Beckenham
About 193 million litres is saved each year in Rossmoyne, Shelley and Waterford
