Abstract：Using rainfall data collected from rain stations in various locations around Wuhan City, the application extent of rainfall intensity equation used in storm sewer design in Hankou is analyzed and select storm rainfall designed by urban waterlogging prevention and its progress graph are determined. The relationship between drainage pipe design standard and urban waterlogging prevention design standard are analyzed. The connection between flow designed for drainage pipe and flow designed by urban drainage pumping station are studied. The different methods of compute flow designed by urban drainage pumping station and flow designed by agricultural drainage pumping station are identified. At last, the computational method of designed flow for drainage pumping station in urban is proposed.
