To avoid pollution of water of industrial, domestic and agricultural origin in recent years have been introduced more and more restrictive laws that commit companies and public administrations to give particular attention to prevention, control and reduction of water pollution. New technologies have hence been introduced to promote a more cautious and less waste-oriented use for water.
Sustainable use of water, infact, is based also on waste reduction or its recycling in productive cycles: these practices can increase availability and improve quality of water existing in a given area. The problem remains, instead, in those countries where these laws haven’t been adopted yet or where serious controls are not undertaken on their application. In this case it’s desirable that industrialized countries should find efficient ways to transfer clean technologies and adequate environmental laws also to poor countries that don’t apply them either.
