A first opening/closing part(100) introduces sewage and initial rainfall. A second opening/closing part(200) is installed at a second intercepting sewer(230) buried in the underground in the sewerage. A reservoir tank(400) connects the first intercepting sewer and the second intercepting sewer. A foreign material eliminating unit is installed in the reservoir tank. |
