In view of the pollution problem of rain and sewage overflow in old urban area, the pollution characteristics and the pollution load are calculated and analysed, and then it is proposed that the initial rainwater storage technology be used to deal with the rainwater and sewage overflow. Based on the rainfall datas of years in Wuhan, and balance rainfall field controlling rate, annual runoff controlling rate and storage area to determine the initial rainfall storage standard. Then, the benefits of storage and disposal are forecasted. Finally, suggestions for further solving the problem of rain and sewage overflow pollution in the old city are put forward.
