There is increasing need for alternative water resources particularly in arid and semi arid regions where average evapo-transpiration exceeds precipitations.In many of these regions the potential usable water resources (M3/capita/year), are below the "water scarcity threshold" with a significant number classified as being under "severe water scarcity".Many Mediterranean regions including Israel are in this category.Forecasts indicate that the situation may aggravate as population continues to grow and standard of life is getting higher and at the same time Global Warming effects and increasing frequency of extreme events are faced.
