The Project
The ACCIONA-led consortium known as the Alkimos SeaWater Alliance will design, build, operate and maintain the future Alkimos Seawater Desalination Plant in Perth for ten years. The Stage 1 design and construct project is scheduled to deliver drinking water in 2028, as part of an overall Water Corporation program of works valued at AU$2.8 billion
Alkimos Water Precinct - will help the region manage the combination of declining rainfall and population growth. Since 1970, winter rainfall in southwest Western Australia has decreased by about 20 per cent while Perth’s population - currently 2.12 million - is expected to reach 2.9 million by 2031 and 3.5 million by 2050, making it Australia’s third largest city and significantly increasing the demand for drinking water.
We're excited to be building this critical piece of infrastructure, and to supply 50 billion litres of climate-resilient drinking water to the region.
