FIELD: agriculture.
SUBSTANCE: livestock drainage and surface waters from a drainage system 1 are collected and accumulated in a closed channel 5, they are pumped by a mobile pumping station 6 through a supply pressure pipe 7 to a storage pond 8. Then, water is released into a brook 11, limiting it so that the content of harmful substances in the water at the end of the brook 11 when entering a river does not exceed the maximum permissible norm. The closed channel 5 is communicated with the channel of the brook 11 by an additional discharge channel 13, which is located perpendicularly to the bed of the brook 11, is made sloping, is equipped with thickets of higher aquatic vegetation, and has a baffling adjustable structure 14. The channel 5 is made with the possibility to transport livestock drainage and surface waters with a variable flow through it. In the storage pond 8, a water intake device is installed, made in the form of a tank 15 with the perforated upper and lower wall, installed in the center of the platform 18, connected to a pressure water conduit with the possibility of forming a water inlet to the beginning of the discharge pipeline 9 and then to the brook 11.
EFFECT: invention allows to increase the efficiency of draining excess drainage and surface runoff into a closed channel and to improve the operating conditions using a brook flowing from a natural water source.
