The Sydney Desalination Plant is a potable drinking water desalination plant that forms part of the water supply system of Greater Metropolitan Sydney. The plant is located in the Kurnell industrial estate, in Southern Sydney in the Australian state of New South Wales. The plant uses reverse osmosis filtration membranes to remove salt from seawater and is powered using renewable energy, supplied to the national power grid from the Infigen Energyowned Capital Wind Farm located at Bungendore. The Sydney Desalination Plant is owned by the Government of New South Wales. In 2012, the NSW Government entered into a 50year lease with Sydney Desalination Plant Pty Ltd (DSP), a company jointly owned by the Ontario Teachers' Pension Plan Board (50%) and two funds managed by Hastings Funds Management Limited: Utilities Trust of Australia and The Infrastructure Fund (together 50%). The terms of the 2.3 billion lease lock Sydney Water into a 50year water supply agreement with DSP. The operator of the plant is Veolia Water Australia Pty Ltd. The Sydney Desalination Plant is the third major desalination plant built in Australia, after Kwinana in Perth which was completed in 2006 and Tugun on the Gold Coast which was completed in 2009. ==Background== Sydney summers during the first decade of the 21st century saw significant declines of dam storage levels. A state of drought in the Sydney catchment areas existed between March 2001 and at least January 2007. Except for 1998, inflows into Warragamba Dam, Sydney's main dam were below average from 1992 until 2006. The last time Sydney's dams were all 100% full was in 1998.〔(Frequently asked questions – Drought ), Sydney Catchment Authority, Retrieved 2010-01-29 (note some of the data on this page needs to be updated as it was written in January or February 2007)〕 Between January 2004 and July 2007, Sydney's available water storage dropped below 55%.〔("Water storage and supply report" ), 28 January 2010, Sydney Catchment Authority, Retrieved 2010-01-29〕 Water supply levels reached their lowest recorded point on 9–10 February 2007 of 33.8%〔("Bulk water storage and supply report" ), 15 February 2007, Sydney Catchment Authority, Retrieved 2010-01-29〕 In November 2009, water storage again dropped below 55%.〔("Water storage and supply report" ), 26 November 2009, Sydney Catchment Authority, Retrieved 2010-01-29 (Report shows levels at 55%. Subsequent reports show decline)〕 The 2004 Metropolitan Water Plan indicated that planning for a desalination plant would be undertaken so that, if the drought continued, it would be possible to construct a desalination plant relatively quickly and efficiently. The feasibility study was undertaken during the first half of 2005 and concluded that desalination is a feasible option for water supply management in Sydney. Other options to supplement Sydney's water supply were ruled out – a new dam was ruled out due to land availability and environmental reasons, drinking recycled waste water and stormwater was ruled out due to lack of community acceptance in Sydney, and rainwater tanks, although encouraged, would not supply enough reliable, potable water, to secure the water supply in times of drought and climate change. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sydney Desalination Plant」の詳細全文を読む スポンサード リンク
