The present invention relates to a bridge drainage facility capable of treating initial rainwater, an initial rainwater inducing method using the drainage facility, and a non-point pollution reducing facility and a method thereof comprising the drainage facility. More specifically, the present invention relates to a bridge drainage facility for inducing initial rainwater generated from a bridge on a river to a non-point pollution reducing facility, which comprises a vertical pipe in connection with a catch pit installed on one side of a road on the bridge; a longitudinal drainage pipe which is connected to both end parts of the vertical pipe respectively, is installed to a reducing facility installed on a ground part of an abutment, and induces the collected initial rainwater to the reducing facility; an overflowing pipe which is installed on one side of each of the vertical pipes, receives excessive water whose amount exceeds the capacity of the longitudinal drainage pipe except for the initial rainwater of the rainwater collected in the vertical pipe, and drains the excessive water to the river, wherein the overflowing pipe is shaped into a curved ��shape, and the length of the vertical pipe is 200 to 450 mm.
Abstract:
PURPOSE: A nonpoint pollutant reducing facility with a sand filtration tank and a nonpoint pollutant reducing method thereof are provided to reduce maintenance costs by reducing unnecessary filtration treatment, since the facility filters only first rainfall, and flows out the rest of the rainfall. CONSTITUTION: A nonpoint pollutant reducing facility (10) with a sand filtration tank comprises a flow rate distribution structure (100), a pre-treatment tank (200), and a sand filter tank (300). The flow rate distribution structure guides first outflow to a distribution water channel by being equipped with a guide projection (110). The sand filter tank is packed with a sand layer, filters the first out flow, and discharges the first outflow to an existing channel. Height adjustment concrete (350) on which a slope is formed is installed on the lower surface of the sand filter tank.

Abstract:
PURPOSE: A nonpoint pollutant reducing facility with a vegetation waterway and a nonpoint pollutant reducing method using the same are provided to improve filtration efficiency of initial rainfall and to reduce maintenance costs. CONSTITUTION: A nonpoint pollutant reducing facility (10) with a vegetation waterway comprises a pre-treatment tank (100), vegetation waterways (200-1,200-2), and an outlet structure (400). The vegetation water way forms an inclined surface from the front side and to the rear side, has vegetation which is plated on the lower side, and stores rainfall effluent inside. The outlet structure takes in the rainfall effluence which flows out of the vegetation waterway, and discharges the rainfall effluent into an existing waterway. A check dam (300) is prepared in between the vegetation waterway and the outlet structure, and provided with an inlet groove (310) on one side of the upper.
