Abstract Urban rainwater utilization is an effective way to solve water shortage and water pollution.By summarizing the exiting theories and technologies of rainwater utilization,some important recent problems in this field were put forward.Setting up runoff generation model and calculating the potential of rainwater utilization,monitoring and managing rainwater quality,planning rainwater utilization in urban areas and applying the rainwater utilization technologies comprehensively were problems that should be studied.The fundamental research direction of urban rainwater utilization will be changed from the qualitative to the quantitative,the urban rainwater utilization technologies will be developed from the single to the integrated,and the urban rainwater utilization will become one of important methods for the urban flood control.
