FIELD: land-clearing.
SUBSTANCE: device contains drainage pipes, connected with catch basins, which with the help of catch-water pipe is jointed with catch basin, connected through catch-water pipe, made with minimal incline, with storm drainage well. Vertical adapter sleeve of catch-water pipe is installed in storm drainage well with return valve made with possibility of discharging creating while drainage water effluent from it. Catch water wells are leakproof. Catch water well connected using catch-water pipe with storm drainage well and fitted with air trap. It is installed lower than every well of catch water, connected with drainage pipes, so that water level in air trap is always lower than lower wall level of corresponding drainage pipe.
EFFECT: cost decreasing for device installation for gathering and removing of drainage water, effectiveness and reliability improvement of its work and simplification of its construction.
