Life on the Earth is possible only under the availability of water, but not any water can sustain life. The article examines questions of the multistage water treatment in economic domestic purposes. The state of clean water supply to the population in Moscow is considered. Recommendations on forecasting a quality of natural waters are proposed according to the factors influencing self-clarification and self-recovery of the contaminated water from natural sources. Main kinds and sources of contamination of water bodies of anthropogenic origin are established. Investigations of water in the intakes of the East, North, West and Rublyevskaya stations were carried out according the quality indicators: chromaticity, biochemical oxygen demand, ammonium nitrogen concentration, annual quantity of phytoplankton, coli-index value. Changing of these values is analyzed. It is established that water quality is the basic factor for determination of the quantity of reagent-cleaner (coagulant, flocculant, activated carbon pulps, potassium permanganate, sodium hypochlorite, ozone). Water bacterial pollution of Rublyevskaya and West stations is an actual problem but the Moscow water treatment plants are characterized by a high quality of water treatment according to all the controlled parameters.
