France’s Degrémont, which built the first Perth desalination plant in 2006, is to operate and maintain all the Western Australian city’s water and wastewater assets for 10 years with a possible 5-year extension.
This will include two advanced water recycling plants as well as 13 dams, 19 water treatment plants and 14 wastewater treatment plants. The Suez Environnement subsidiary already has a 25-year contract to operate and maintain the 45 million m³/year Kwinana desalination plant.
The contract, which will start in July 2012, is valued at € 294 million (US$ 365 million) over the initial term. Degrémont, Transfield Services and Water Corporation will form an integrated alliance which will be named Aroona.
