Already there is more waste water generated today than at any other time in the history of our planet: more than one out of six people lack access to safe drinking water, (namely 1.1 billion people), and more than two out of six lack adequate sanitation, (namely 2.6 billion people)*. 3900 children die every day from water borne diseases**. One must know that these figures represent only people with very poor conditions. In reality, these figures should be much higher.

Recently a new concept “water stress” was introduced. The concept of water stress is relatively simple. According to the World Business Council for Sustainable Development, it applies to situations where there is not enough water for all uses, whether agricultural, industrial or domestic.

It has been proposed that when annual per capita renewable freshwater availability is less than 1,700 cubic meters, countries begin to experience periodic or regular water stress. Below 1,000 cubic meters, water scarcity begins to hamper (препятствовать) economic development and human health and well-being.
