Abstract: 
Severe operational problems of sediment deposition have frequently occurred in stormwater sewer systems in Shanghai city due to the flat topography of the area and serious illicit connections. To control sewer sediment and its subsequential problems, optimized operation plans were proposed and an innovative performance assessment method was developed. simulation results demonstrated that, through changing the way of pump operation and installing necessary actuators in the system, the optimized operations, especially batch intermittent intercept plan, effectively improved the flow velocity in the entire system in dry-weather condition. In conclusion, the optimized operation is an innovative idea for improving the performance and solving the problem of sediment deposition in the sewer system in Shanghai, China.
