Water used in towns is chlorinated, however in 1996 and part of 1997 chloring of water was practically not carried out. There are effective methods of biological purification of communal sewage. Interesting to note that many enterprises apply the principle of renewable water supply. One of the largest mining enterprises in Tajikistan use special waterproof covering of tailing bottom for the purpose to prevent underground water pollution. Around large enterprises, towns and cities are frequently made the underground water tests.
Special services carry out inspection of enterprises.
But all undertaken measures are inadequate because of enormous quantity of communal waste amassed alongside of basins and essentially affecting them, lack of financing, decrepitude and small efficiency of sewage treatment equipment.
