2008 Winner
Perth Seawater Desalination Project, Kwinana, WA Brookfield Multiplex
The $300 million plant for the Water Corporation of Western Australia is a key initiative of the Western Australian Government to provide approximately 17 percent of Perth’s drinking water. The project was delivered by the proAlliance consisting of Multiplex Engineering, Degremont SA and the Water Corporation WA.
The project involved the design and construction of a 144 ML/day seawater reverse osmosis desalination plant, which is the third largest in the world, in an 18-month period. The unique design, procurement, construction and operation of the plant, including the use of renewable energy, energy recovery, the relatively small, ecological footprint and extensive ocean monitoring program, makes the project a truly sustainable, climate independent water source.
The plant was successfully built on a footprint of only 6.3 hectares and encompassed the installation of intake and outfall pipelines and an intake receiving structure within the protected waters of Cockburn Sound.
The processes developed for the project were far more complex than for any conventional water treatment plant, not only because of issues relative to the corrosive nature of seawater, but also in producing a pristine quality of seawater to feed the reverse osmosis system.
The key environmental challenges such as consultation, approvals and regulations, concentrate management and marine monitoring, energy and aesthetics, were all paramount during all stages of construction and will continue for throughout the life of the plant.
