NON-POINT SOURCE CONTAMINANT TREATMENT SYSTEM

摘要

A non-point contaminant source treatment system is provided to prevent the contamination of the public water area and the underground water. A concrete box(10) includes an inflow port(11) and a cover surface(13). The inflow port is opened and outflow water is transferred via an outside inclination surface(13). The first hole discharge pipe(20) collects the outflow water treated at a hollow member of the concrete box and transfers the outflow water to a public water area. The second hole discharge pipe(30) includes holes formed at the bottom of the concrete box so that the outflow water is infiltrated into the underground. A bypass pipe(40) is installed at the hollow portion of the concrete box.
