The connection port of the overflow pipe 4 and the catch basin 1 is close to the opening of the catch basin 1. The other end of the overflow pipe 4 is communicated with a municipal rainwater pipe. The blow-off pipe 9 is communicated with the bottom of the catch basin 1. The bottom of the catch basin 1 is of a bucket-shaped structure with a low middle part and high periphery. One end of the sewage discharge pipe 9 is communicated with the lowest part of the bottom of the catch basin 1. The other end of the blow-off pipe 9 is communicated with a municipal sewage pipe. The upper end of the catch basin 1 is provided with a rain grate 2. The rainwater grate 2 covers the opening of the rainwater well 1. The upper surface of the rain grate 2 is flush with the road surface. The catch basin 1 is provided with a receiving hanging basket 3. The accommodating hanging basket 3 is a woven basket or a bag which is permeable to water and is not easy to rot. The object-receiving hanging basket 3 is positioned below the rainwater grate 2 and above the overflow pipe 4. The article-holding hanging basket 3 is arranged in a cavity surrounded by the filter layer 6. A rotatable cover plate 7 is arranged in the cavity of the catch basin 1. The cover plate 7 is positioned above the sewage draining pipe 9 and below the water storage tank connecting pipe 10.
