METHOD FOR PROTECTION OF WATER RESERVOIR AGAINST CONTAMINATION Russian patent published in 2010 - IPC E02B3/04 E02B11/00 

FIELD: construction.

SUBSTANCE: method for protection of water reservoir against contamination includes arrangement of draining elements in body of water reservoir slope massif in one or several tiers that consist of working or downstream parts. When draining elements are arranged in several tiers, at first next to each output hole of downstream parts of draining elements of each tier, technical platforms are arranged with solid surface, starting from the upper one, and then road is arranged for passage of motor transport, which connects all technical sites, besides access section of this road is connected to existing motor road. From each technical site in massif of slope, below downstream parts of draining elements at the depth, in which their bottom is arranged at least by 0.5-1 m below water level in water reservoir, collection reservoirs are arranged to capture filtering ground water flow contaminated with hazardous substances, besides lower output holes of downstream parts of draining elements, having slope to the side of water reservoir, are joined directly to collection reservoirs, and collection reservoirs themselves are equipped with opening covers, through which it becomes possible to pump contaminated water with hazardous substances coming from working and downstream parts of draining elements. Pumping of contaminated filtered ground flow is done avoiding increase in liquid level in these collection reservoirs higher than water level with the help of pump equipment installed in motor transport with reservoir for transportation of liquid wastes, and transported to treatment facilities station.

EFFECT: increased protection of water reservoir against ingress of contaminating substances to it from contaminated ground waters.
