    Adelaide Desalination Plant

    The plant was built in two phases, reaching a 300 MLD capacity. Delivery of full capacity by end of 2012.

    The Adelaide Desalination Plant has been operating continuously since completion and has delivered more than 30 GL of desalinated drinking water into the SA Water supply network (current as of end-February 2013). This is a very large asset for South Australia and 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.

    The technology used in ACCIONA Agua’s design makes this desalination plant a global benchmark. This design brings a number of important benefits, such as:

    • An advanced pre-treatment process that provides high levels of reliability, less energy use and a reduced need for chemicals.
    • A highly efficient reverse osmosis design which will enable more efficient use of extracted seawater, significant energy savings and a smaller plant footprint.
    • An innovative diffuser design for the saline concentrate that will ensure adequate mixing back into the marine environment and ensure environmental performance criteria.
