Calculating the Quantity and Cost of Distilled Water Produced by Solar Plants to Desalinate Drain Water and use it in Irrigation

Abstract Industrial and agricultural growth, population explosion, as well climate change all over the world have led to a significant increase in demand for fresh water, so obtaining it simplest, cheapest most appropriate way has become challenge many countries, including Iraq. The aim of study is invest free solar energy through use stills desalinate water production mixing drip techniques. results showed possibility arable construction network virtual stills, process distilled with an equal amount drainage using irrigation, was found that cost one liter used agriculture (1.077 IQD) (0.0007 $, i.e. 0.0007 $ Less than cent) within 20 years (the lifespan project), where group crops can be grown according produced default design distillers salt such chickpeas, cabbage lentils.
