Funds totalling $19 million have been committed to doubling the Western Australian Water Authority's Beenyup wastewater treatment plant's capacity by 1997.
Water Resources Minister Ernie Bridge said more than $9 million would be spent on the project in 1992-93.
He said this meant the start of stage three of the on-going development of this major northern suburbs treatment facility, commissioned 23 years ago.
"Stage three will eventually lift treatment capacity to 150 million litres a day from the present capacity of 75 million litres," Mr Bridge said.
"The decision to make a start on stage three follows a recently completed duplication of the pipeline, which discharges the high standard effluent off Ocean Reef.
"The effluent is discharged following treatment to standards imposed by the Environmental Protection Authority, which ranks with the highest in the world," he said.
"There will be absolutely no compromising on those standards despite the fact that the amount of effluent will increase through the 1990s as the north-west corridor development continues."
Mr Bridge said the project would be designed and constructed by WAWA personnel, with input from external consulting engineers, specialist sub-contractors and wastewater equipment and process control equipment suppliers.
