Coping with population growth and low rainfall

An ACCIONA-led consortium has been selected as the preferred proponent by Water Corporation, the largest water utility in Western Australia, to design, build, operate and maintain the future Alkimos Seawater Desalination Plant (ASDP) in Perth for ten years. The plant will have an initial (Stage 1) capacity of 150,000 m³ per day, with an additional 150,000 m³ per day, when required, under Stage 2.

The project will be delivered as an alliance, comprising of Water Corporation, ACCIONA and Jacobs, and has safety and wellbeing at the forefront of delivery, as well as embedding sustainability in the design, delivery and operations of the plant.

The commissioning of ASDP - to be built within the 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.
