Unlike other natural resources water renews itself. This is due to its constant circulation in the ocean – atmosphere-earth-ocean system.No matter how much water is consumed in daily industrial life, its amount does not decrease. With time and under certain conditions water regains its properties and its fitness for drinking.
This is probably the reason why water resources for a long time appeared to be unlimited. However, this view has substantially changed in the past 30 or 40 years, when water become a factor which dictates prospects for economic development. In the economy water is a raw material like any other. Scarcely any type of product is manufactured without water taking part inthe process in one form or another. The obtaining of a tonne of paper or woolen fabric requires the use of 200 cubic metres of clean fresh water, that of a tonne of capron 5.600 cubic metres.
The use of water leaves it polluted. Newspapers report that all the large rivers in Britain, Australia, Belgium, the Federal Republic of Germany, Sweden, Italy the United States,the Netherlands, Spain and many other industrially developed countries are completely or partially polluted.
