Urban drainage engineering plays a pivotal role in the overall functionality and sustainability of modern municipal infrastructure. It encompasses critical components such as sewage treatment systems, pumping station construction, and urban road integration. This study examines the prevailing challenges in the construction of urban drainage systems and provides strategic recommendations for improving project planning and execution. Drawing from both domestic and international research, the paper explores the significance of specialized design in sewage projects, particularly in urban contexts facing rapid development pressures. Key aspects analyzed include the accuracy of sewage volume forecasting, the selection of appropriate sewer systems, and the optimal siting of rainwater pumping stations. Through detailed case analysis and site planning considerations, it is recommended that the distance between rainwater pumping stations and adjacent buildings should exceed 35 meters to mitigate operational and environmental risks. Sewage project implementation. The findings offer valuable reference points for the formulation of effective, scalable, and context-specific urban drainage solutions.
