Western Australia will invest $81 million to expand the Kwinana Water Reclamation Plant, with the Cook Government saying the project will strengthen climate resilience, support job-creating industries and help diversify the state’s economy.
Premier Roger Cook said Western Australia’s economy is “the strongest in the nation” and said that is why his government is “providing a sustainable supply of water to new and emerging industries that will be key to the State’s future.” He added that “expanding the Kwinana Water Reclamation Plant is critical to diversifying WA’s economy.”
Cook said the investment would directly support business growth in one of the state’s most important industrial areas. “By providing water to emerging industries in Kwinana, my government is supporting job-creating projects which will help keep our State’s economy the strongest in the nation,” he said.
Water Minister Don Punch said the expansion will deliver more recycled water for industry and help businesses operate in a cleaner and more efficient way. He said, “This $81 million expansion of the Kwinana Water Reclamation Plant will deliver more recycled water for industry, helping drive economic growth while supporting cleaner, more efficient operations.”
Punch said demand for water in the Kwinana Industrial Area is growing as established industries expand and new clean energy sectors emerge. “Demand for water in the Kwinana Industrial Area is increasing as established industries grow and new clean-energy sectors take shape - making secure, reliable water supplies essential for future investment,” he said.
He also said recycling wastewater is a practical and cost-effective response to that pressure. “Recycling wastewater offers a cost-effective way to meet this demand while protecting precious scheme water and groundwater. This upgrade not only supports industry but strengthens Western Australia’s long-term environmental sustainability,” Punch said.
The project is designed to increase recycled water supply for industrial users in Kwinana and reduce pressure on scheme water and groundwater. It also supports the state’s broader push to back sectors such as green hydrogen, advanced manufacturing and other emerging industries that need secure water access to grow.
Kwinana has long been central to WA’s water recycling strategy, and this expansion builds on that legacy by turning wastewater into a more reliable industrial supply. The state is presenting the project as both an economic infrastructure investment and a climate adaptation measure.
