A '''reverse osmosis plant''' is a [[factory|manufacturing plant]] where the process of [[reverse osmosis]] takes place. An average modern reverse osmosis plant needs six kilowatt-hours of electricity to desalinate one cubic metre of water.{{Fact|date=August 2007}} The process also results in an amount of salty briny waste. The challenge for these plants is to find ways to reduce energy consumption, use sustainable energy sources, improve the process of desalination and to innovate in the area of [[waste management]] to deal with the waste.{{Fact|date=August 2007}}
==Examples of reverse osmosis plants==
''In operation''
*In [[Israel]] at [[Ashkelon]] on the [[Mediterranean]] coast, the world's largest reverse osmosis plant is producing 320,000[http://www.veoliawater.com/access/press/?news=1127] cubic metres of water a day at around possibly 50 US$ cents per cubic metre.{{Fact|date=August 2007}}
''Under construction''
*In [[China]] a desalination plant will be built for [[Tianjin]], to produce 100,000 cubic metres of desalinated seawater a day.{{Fact|date=August 2007}}
*In [[Spain]] 20 reverse osmosis plants will be built along the Costas,{{Fact|date=August 2007}} expecting to meet slightly over 1 per cent of Spain's total water needs.{{Fact|date=August 2007}}
