The Adelaide Desalination plant, formerly known as the Port Stanvac Desalination Plant, is a SWRO (sea water reverse osmosis) desalination plant located in Lonsdale, South Australia which has the capacity to provide the city of Adelaide with up to 50% of its drinking water needs. On 11 September 2007, South Australian Premier Mike Rann announced that the State Government would fund and build a desalination plant to guarantee Adelaide's water supply. He said the plant, to be totally powered by renewable energy, would be 'a necessary insurance policy against future droughts'.〔ABC News, Sept 11,2007 (reporter Nick Harmsen〕 In February 2008, the State Government appointed SA Water as the lead agency responsible for the delivery of the project and also appointed a Steering Committee of Chief Executive of key Agencies to provide strategic oversight and review of all key decision prior to approval by the SA Water Board and or the Government and Parliament; this Steering Committee had an Independent Chair (Mr. Kevin Osborn). On 13 May 2009, following negotiations between the Premier and Prime Minister Kevin Rudd, it was announced that the Adelaide Desalination plant would be doubled in size following extra Federal funding.〔SA Govt New Release, 13 May 2009 "Adelaide to double size of its Desal plant", www.sawater.com.au/〕 The plant was completed on time and within the original budget ($1.83 billion). It has an estimated operating cost of $130 million per year ($2.5 million per week), when operating at full capacity of 100 GL per annum. It was officially opened on 26 March 2013.〔http://www.premier.sa.gov.au/images/news_releases/13_03Mar/desal.pdf〕 The capital cost of A$1.824 billion for the Adelaide Desalination Project includes: # The desalination plant and associated marine works # A pumping station and 12 km transfer pipeline to take the desalinated water to the Happy Valley Reservoir Treatment Plant (Treated Water tanks) where it is blended with treated catchment rainwater and delivered into the SA Water distribution system # SA Power Networks electricity supply sub-station # Preliminary site works, land and other interconnection works with SA Water's existing facilities The Adelaide Desalination Project is (and remains) the largest infrastructure project that the State of South Australia has funded, owns and has completed successfully - to date. ==Background and Project Challenges== South Australia, as the "driest state in the driest ''(inhabited)'' continent",〔Griffin, T. & McCaskill, M. (1986): ''Atlas of South Australia'', South Australian Government Printing Division. p 60.〕 has experienced severe water shortages during periods of drought. As drought conditions worsened during 2006-7, reduced inflows into the River Murray lead to the introduction of progressively harsher water restrictions and the future of Adelaide's water supply came to the fore as a political issue.〔(Libs' user-pays water plan ) Michael Owen, ''AdelaideNow'', 29 August 2007. Retrieved 26 August 2011.〕 Although there had been some prior consideration at state government level for a desalination plant to supply metropolitan Adelaide, in the leadup to the November 2007 federal election campaign Prime Minister John Howard promised that, if re-elected, his Coalition government would contribute towards the capital cost of a desalination plant to reduce the city's dependence on the River Murray. Opposition leader (then) Kevin Rudd made similar pledges.〔(Howard's desal plan to wean city off Murray ) Pia Akerman and Siobhain Ryan, ''The Australian'', 23 October 2007.
