FIELD: construction.
SUBSTANCE: invention deals with the facilities intended for preventing or minimising ground water pollution. Geo engineering barrier includes geo engineering barrier 1 and geo engineering barrier 2 being above the first one and distanced from it. At least, one out of two barrier layers is geo synthetic barrier layer. Besides, both barrier layers define at least, partially, the limits of fluid passage. The fluid passage is provided with inlet, outlet, and fluid displacement facility. The latter is connected to passage outlet and designed so that it can create negative pressure regarding inlet pressure, thus ensuring fluid movement from inlet to outlet.
EFFECT: reduction of pollution rate in facilities being protected.
