Abstract: This study selected a residential area in Ningbo City as the research area and modeled the sewage network using Infoworks software. By integrating single-day electricity price fluctuations, service area sewage discharge patterns, and drainage network topologies, the daily electricity cost of the pumping station, pump start-stop frequency, and flood depth are designated as preferred objectives, employing the fuzzy optimization method and multi-objective optimization methods to analyze and optimize the effective volume of sewage pumping stations. The optimal effective volume of the pumping station obtained by optimization can save 15.9% of the daily electricity cost and reduce 13.3% of the start-stop cycles of the pump when there is no overflow event in the drainage system, which significantly reduces the operating cost of the sewage pumping station. This study can provide theoretical support for the optimization of drainage pumping station volume as well as economical operation.
