A sewage basin capable of receiving rainwater is provided to filter sewage mixed in rainwater and collect the deposits for a while in a dust collecting container, so as to allow the deposits to be easily discharged to the outside through the dust collecting container, while preventing rainwater from entering the sewage basin by selectively using a screen plate. A sewage basin(3) capable of receiving rainwater comprises an upper body(10), a lower body(20), a filtering mesh(14), and a dust collecting container(40), a joining pipe(43), and a screen plate(50). The upper body has a passage(11) on the inside to drain rainwater to a rainwater pipe(1) buried underground, a rainwater drainage pipe(12) connected to the passage, and a cover(13) for closing its upper side. The lower body comprising a bottom plate(21) and a sidewall(22) surrounding the bottom plate, is connected to the upper body, wherein the sidewall comprises a sewage inlet pipe(23) connected to a service pipe, and a sewage outlet pipe(24) to drain supplied sewage to a sewage pipe(2). The filtering mesh is installed on a drainage line through which the rainwater drains to prevent sewage mixed in the rainwater from entering together with the rainwater. The dust collecting container is accommodated in the passage, having a drainage hole through which deposits that are filtered by the filtering mesh are discharged. The joining pipe connects the drainage hole of the dust collecting container and the rainwater drainage pipe for packing. The screen plate is disposed between the upper and lower bodies to prevent rainwater from entering the sewage basin. |
