FIELD: agriculture.
SUBSTANCE: method includes an irrigation section 1, drains 2 flowing into a closed manifold 3 that is connected to the outlet part of the pipe 4 with a slope towards the open channel 5. A deep discharge drain 6 laid parallel to the open channel 5, sprinkled with a fertile layer 8 along the edge length of the channel 5, is connected to a vertical drain 9 above the upper boundary of the tubular manifold 3. The vertical drain 9 is made with a surface water collector made of a plastic pipe having circumferentially perforated water intake openings in the middle part to collect the filtration waters of the deep discharge drain 6 with the outlet part 4 and the manifold 3. The vertical drain 9 is filled with a protective filter material of coarse one-size gravel above the upper boundary of the tubular manifold 3. The upper end of the plastic pipe is connected by a clamp to a flare nozzle in the form of a bowl, the top of which is covered with a protective mesh with small cell sizes. Surface and filtered water from the area of watering with livestock sewage is directed through the vertical drain collector and the discharge part first to the drainage open channel 5, then to the drainage storage pond 17 arranged in the local relief depression.
EFFECT: increasing the efficiency of the drainage structures and their service life under the conditions of watering by sprinkling systems with livestock sewage on the drainage-humidification system, as well as the stability of the slopes of the drainage channels and preserving ecological requirements for the environment.
