The State Government will provide $352 million over the next five years to upgrade three main metropolitan wastewater treatment plants.
Water Resources Minister John Kobelke today announced the upgrade to the Beenyup, Woodman Point and Subiaco wastewater treatment plants would be one of the most significant ever undertaken.
The three plants treat about 80 per cent of the State's wastewater and the upgrades would help underpin Perth's long-term, sustainable growth by improving the Water Corporation's operational capacity and ability to better managing the odour impacts.
As part of the upgrade, $147 million would be spent at the Beenyup wastewater treatment plant, $137 million would be spent at the Woodman Point plant and $68 million would be spent at the Subiaco wastewater treatment plant.
"Efficient and reliable wastewater treatment plants and systems are an essential part of modern societies," Mr Kobelke said.
"The significant work that we are undertaking now will ensure that Perth can continue to grow well into the future, while protecting public health and amenity, as well as the environment."
The upgrade will increase the capacity of the Beenyup and Subiaco wastewater treatment plants by at least 15 million litres a day at each plant, while maintaining their current high standard of odour control.
The Woodman Point wastewater treatment plant's solids treatment capacity will increase to align with the overall hydraulic capacity of the plant of 160 million litres a day and the level of odours from the plant will decrease by 50 per cent within three years.
The work will be delivered in an innovative Alliance Agreement that will involve the Water Corporation working with an engineering and construction consortium consisting of Black and Veatch Australia; Sinclair Knight Merz; and Thiess.
"As well as being one of the most significant wastewater projects we have undertaken, it will be the first time that a project of this scale will be conducted simultaneously across all three sites," the Minister said.
Mr Kobelke said the Water Corporation's metropolitan wastewater operations play a vital role in supporting Perth's sustainable expansion.
"Properly treated wastewater is an important resource and recycling water to meet some of our water needs is becoming increasingly important with Western Australia's drying climate," he said.
"Through a number of Government initiatives, the use of recycled water in Perth is growing steadily and there are many projects being implemented and investigated as part of the State Water Strategy that will lead to further major improvements."
