FIELD: ecology.
SUBSTANCE: invention relates to the protection of underground and surface waters from a polluting sewage stream of livestock complexes, SDW landfills, oil products, containment ponds, etc. Pollutants, penetrating into the subsoil water, move in the direction of their movement and can spread to large areas. A geomembrane 2 with filtering windows is placed in the main trench 1 as an impervious material. A water intake tank and a pump 7 for pumping floating contaminated dissolved matters from the upper layer of water 8 are placed in an impervious curtain. Valves 9 are installed on the filtering windows and pumps 7 create a forced movement of subsoil water.
EFFECT: speed of subsoil water movement rises and thus the efficiency of subsoil water purification from pollutants increases.
