The total project cost is $1.83 billion and the plant will deliver up to 100 billion litres of water each year (100GL) (about half of Adelaide's annual water supply).
Port Stanvac has been chosen as the preferred site for the plant due to the accessibility of relatively deep seawater, optimal marine dispersion characteristics, better access to the water supply network, suitable land availability and lower construction costs.
First water will be delivered via the plant in December 2010. The plant will be fully operational in late 2012.
A multi-national consortium, AdelaideAqua has been named as the preferred bidder for construction of the desalination plant. The consortium of four companies has extensive world-wide desalination experience and strong environmental credentials. The companies comprise Spanish firm Acciona Agua, United Utilities, McConnell Dowell and Abigroup Contractors. Together they will design, build, operate and maintain the plant for 20 years. AdelaideAqua was selected after a competitive and comprehensive evaluation process.
