A countermeasure to mitigate combined sewer overflows is proposed: when rain is relatively small, all the polluted runoff water is stored in a combined sewer pipe system; all the stored water is transported into a treatment plant during and after the rain, treated, and drained into public water bodies.When, at the downstream ends of 6th and 4th order sewer pipes, control gates are installed and all the polluted runoff water is stored in the sewer pipes of 6th, 5th, 4th, and 3rd order, then the rain water amount of 10 mm will be able to be stored in the pipes; and 30 or 40 percent of the polluted runoff water that has been overflowed out of the pipe system without any treatment will be able to be treated and drained into public water bodies.

提出了缓解合流制污水溢流的对策：当降雨量较小时，将所有受污染的径流水储存在合流制污水管道系统中；雨中雨后所有储存的水均输送至处理厂处理后排入公共水体。六级、四级污水管道下游端安装控制闸门，所有受污染的径流水均经过处理后排入公共水体。储存在6、5、4、3级下水管道中，则管道中可储存10毫米的雨水量；未经处理而从管网溢出的受污染径流水的30％或40％将能够得到处理并排入公共水体。
