By investigating a certain inland river port project，this paper studies several difficulties in the technological design of water intake pump houses. To reduce the sediment deposition in the inlet pipe，this paper adopts the calculation formula for the non-deposition flow velocity of sediment to determine the flow velocity in the inlet pipe. Considering that the current Standard for Design of Outdoor Water Supply Engineering fails to specify the design elevation of a water intake pump house located at the front of a wharf，this study carries out a comparative analysis of the relevant codes and presents a determination principle. The results show that when the inlet pipe is short and the hydraulic loss is small，the personnel concerned can increase the flow velocity in the inlet pipe to a proper extent according to the calculation formula for the non-deposition flow velocity of sediment. They can determine the design high water level at the entrance floor comprehensively in accordance with the classification of the pumping station on the premise that it is not lower than the flood control level of the port. They can also obtain wave height by referring to the top elevation of vertical breakwaters rarely subject to overtopping.
