The water resources of the Near East, where approximately the twentieth part of the people of the Earth live, today hardly provide for the normal life of this regions population. According to approximate estimates the reserves of sweet water here are less than the hundredth part of the world reserves. On a global scale the problem of water in the Near East is certainly part of this problem. According to the data of the World Health Organization more that 2 billion people suffer from the lack of drinking water in the world. It has a whole number of causes. The demographic factor is very important among others: during the XX century the Earth's population has grown as much as three times, where as the consumption of sweet water has increased as much as 13 times on the whole reaching the level of 3.5 trillion cubic meters per annum.
