THE Woodman Point Wastewater Treatment Plant will undergo a $196m expansion the State Government says will boost capacity by 40 million litres a day.
Upgrades to the state’s largest wastewater treatment plant will include construction of a new grit removal facility, a new flow distribution channel, expansion of existing odour collection and treatment systems, new sedimentation tanks and conversion of the existing batch reactor to a permanent aeration facility.
Water Minister Mia Davies said the upgrades would increase the plant’s capacity from 140 million litres a day to 180 million litres, and play a major role catering to a growing population.
“The Woodman Point plant is a critical part of Perth’s wastewater treatment network and it currently serves about 680,000 people,” she said.
“Once this large program of work is completed, it will be able to accommodate 900,000 people.”
Construction will begin next year and is due for completion in 2019.
Black and Veatch Australia and Henderson firm Civmec were selected to undertake the work, which is due to finish in 2019.
The plant serves an area south of the Swan River bounded by Kalamunda in the east, Byford in the south, and the coast to the west.
