Adelaide Desalination Plant

The plant was built in two phases, reaching a 300 million litres per day (MLD) capacity. The plant has been operational since December 2012.

The Adelaide Desalination Plant has been operating continuously since completion and has delivered more than 130 gigalitres of desalinated drinking water into the SA Water supply network (current as of end-December 2015). This state significant South Australian asset provides 50% of Adelaide's drinking water needs from a climate-independent source. 

Having this asset completed, operational and delivered on-time, has eliminated water restrictions in South Australia and improved the diversity and reliability of water supplies to business and communities in South Australia.
