The Use and Protection of Potable Water Supply Sour ces
Conditions of formation of water quality in potable water supply sources of Moscow are expounded. Main reasons for contamination of natural water as a result of anthropogenic activities at water collecting territories of rivers and lakes are enumerated. For the Moskva water source the problem of entering of contaminants is on the agenda as one of the most acute. Main methods of the solution of problem of water quality in water sources as well as measures aimed at enhancement of aqueous medium are specified.
Key words: surface water supply sources, potable water, storm and domestic wastewater, treatment facilities.

Increase of Effectiveness of Water Clarification Process
An automatically regulated variant of the clarification block realized at one of process lines of the experimental water treatment station at the Rublevskaya water treatment station is presented. Long-term operation of this facility has shown its flexibility, economy, excellent operation characteristics, and the highest technological efficiency. Such organization of the process makes it possible to eliminate all main shortcomings typical for water treatment facilities operated at the Moscow water supply stations with minimal possible expenses.
Key words: water treatment, clarification, chromaticity, permanganate oxidizability, coagulation, flocculation.
