FIELD: process engineering.
SUBSTANCE: invention relates to ecology and is intended for decreasing contamination of ground waters in infiltration of atmospheric precipitation through stored wastes depth. To this end, contour anti-filtration screen is constructed combined with exposed and closed drainage devices, and accumulator tank is prepared made up of separated sections intercommunicated by troughs or bellows. Sais tank is arranged on dump pit. Closed drainage is provided with water collection well. Water is fed to dump and tank from water collection well by sprinkling units.
EFFECT: efficient ground water protection against pollution.
