At present, many cities in China have both severe water shortages and waste of large amounts of rainwater resources during heavy rains caused by urbanization. Turning rainwater resources into cities can reduce urban runoff and reduce peak floods. At the same time, it can increase urban water supply, beautify and clean the urban environment, improve urban microclimate, reduce ground subsidence, control rain and flood processes and reduce urban flood control. Drainage infrastructure investment greatly reduces urban flood disasters, which will bring considerable economic, social and environmental benefits. Therefore, as one of the hot topics in the preparation of special plans for drainage engineering in the new period, urban rainwater should be carried out using the SWMM model and computer software. The plan provides the possibility for further compiling special plans for rainwater utilization and guides the utilization of urban rainwater resources.
