- Cook Labor Government investing $81 million in expansion of Kwinana Water Reclamation Plant to supply four Olympic-sized swimming pools of additional recycled water daily
- Supports existing and emerging industries, including green iron and steelmaking, battery mineral processing, and fuels and energy
- Reduces pressure on groundwater and scheme water supplies
The Cook Labor Government is investing $81 million to expand the Kwinana Water Reclamation Plant (KWRP), backing local jobs and giving industry the water security it needs to grow and diversify Western Australia’s economy.
This upgrade will deliver the equivalent of four Olympicsized swimming pools of recycled water every day, giving emerging industries in the Kwinana Industrial Area the certainty and capacity they need to grow.
Operational since 2004, KWRP currently supplies almost 17 million litres of recycled water daily to major industrial customers. The expansion will add a further 10 million litres a day, boosting production by 60 per cent and extend the plant’s life by 25 years, supporting the Cook Labor Government’s long-term water security strategy.
Using advanced microfiltration and reverseosmosis technology, the plant treats wastewater from nearby water resource and wastewater facilities to produce highquality recycled water for industrial and cooling uses. Increasing recycling capacity will reduce pressure on groundwater and scheme water while lowering costs for industry.
The project will help drive investment in fastgrowing sectors such as green iron and steelmaking, battery mineral processing, and fuels and energy, and supports Water Corporation’s longterm recycling goals and the Cook Labor Government’s broader sustainability strategies.
Located within the Western Trade Coast, one of Australia’s most productive industrial regions, the upgrade strengthens water security for a precinct that contributes about $20 billion annually to the national economy and supports around 30,000 jobs.
Construction of the first phase is nearing completion, delivered by Australian contractor BMD Constructions. The second phase, the construction of the new 3kmsupply pipeline, is due to commence in July.
As stated by Premier Roger Cook:
“Expanding the Kwinana Water Reclamation Plant will provide industry with a greater supply of highquality recycled water needed to help grow and diversify our economy.
“As one of the world’s largest exporters of critical minerals for battery production, and an emerging hub for green iron and steelmaking, Kwinana is positioned to become a major player in global decarbonisation.
“With water essential to these industrial processes, this expansion will help attract new investment to one of Australia’s most productive industrial precincts, underpinning economic growth and supporting thousands of Western Australian jobs.”
As stated by Water Minister Don Punch:
“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.
“Demand for water in the Kwinana Industrial Area is increasing as established industries grow and new cleanenergy sectors take shape – making secure, reliable water supplies essential for future investment.
“Recycling wastewater offers a costeffective way to meet this demand while protecting precious scheme water and groundwater. This upgrade not only supports industry but strengthens Western Australia’s longterm environmental sustainability.”
