In April 2005, the Water Corporation of Western Australia entrusted Degrémont with the design, construction and operation (for the next 25 years) of the first reverse osmosis facility for Perth.
In November 2006, the first water was fed into the first two 2 reverse osmosis racks.
The plant has been operating at maximum output since mid-January 2007: 144,000 m3/day. The Perth facility uses state-of-the-art technologies, especially a new pressure-exchange energy recovery process that improves conventional performance by 15 to 20%.
In order to minimise the impact of the brackish water impact, Degremont has iintroduced a 500-metre discharge pipe, perpendicular to the current in the bay.
Furthermore, Water Corporation has signed an agreement so that 100% of energy needs of the plant are provided by a wind farm, situated 200 km north of Perth.
