METHOD FOR PREVENTING THE INFLOW OF SURFACE WATER FROM THE TERRITORY OF AREAL AND POINT SOURCES OF POLLUTION Russian patent published in 2022 - IPC A01B13/16 E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used in the construction and operation of point and area sources of pollution in agriculture. The method includes creating a trench across the direction of surface water runoff. In the lower part of the slope, perpendicular to said trench, drainage trenches with a non-zero slope are built to drain the filtered liquid fraction of runoff flows and an associated storage pond. Two layers of material are laid on the bottom and walls of the trenches, of which the upper one is filtering, the lower one is waterproof, crushed stone is poured between them for a drainage effect, and a forest strip is laid below the trench, reinforced with a shaft along the lower edge.

EFFECT: method ensures prevention of pollution by surface runoff of ground and surface waters, retention of solid fraction of surface runoff, water saving, increase in the durability of the forest belt and the possibility of using it on sandy lands with a high filtration rate, on lands with a high level of groundwater, as well as on short slopes.
