The capacity of Water Corporation’s wastewater treatment plant in Onslow, on the midwest coast of Western Australia, has been doubled to 870,000L per day.
Western Australian Water Minister, Mia Davies, said the expanded plant capacity would support the long-term future growth of Onslow, which was fast becoming one of Western Australia’s most significant gas hubs.
“It is expected that, over time, the demand on Onslow’s wastewater infrastructure will nearly double as the population increases in the town,” Ms Davies said.
“These upgrades not only improve the existing plant infrastructure but also put in place the capacity to support long-term growth and ensure a quality service for the Onslow community.”
Western Australian State Development Minister, Bill Marmion, said the upgrade formed part of the Chevron-operated Wheatstone Project’s State Development Agreement and had created local jobs.
“A total of 11 local Onslow contractors worked on this project including crane hire, surveying and supplying materials and 58 people were employed over the life of the project,” Mr Marmion said.
“This is a tremendous example of industry working with the State Government to deliver positive community outcomes in regional WA.”
The Onslow wastewater treatment plant upgrades began in 2014, with final testing completed in November 2016.
The Chevron-operated Wheatstone Project contributed $13.13 million to the upgrade project, with Water Corporation funding the remaining $1.5 million.
