description This study investigated the hydraulic characteristics of stormwater sumps and their design optimization for sediment retention using physical experiments. Particle image velocimetry was utilized to measure the flow field, and the use of internal structures was investigated for improving solids retention. Results indicate that these internal structures can significantly improve the sediment removal efficiency of suspended solids with an average size of 125 μm, resulting in an efficiency improvement of 20–30%. Additionally, a modified Péclet number was proposed to more accurately evaluate the sediment removal efficiency of stormwater sumps, and recommendations were provided for further improving and optimizing sump design. This study provides insights into the hydraulic characteristics of stormwater sumps and has important implications for optimizing and designing particle removal systems for various industrial and environmental applications. HIGHLIGHTS The study demonstrates that incorporating enhancements leads to a substantial increase (20–30%) in the efficiency of removing suspended solids in stormwater sumps.; The study introduces a modified dimensionless number that provides a more precise evaluation of sediment removal efficiency in stormwater sumps.; The study highlights that scaling, with a ratio of up to 6, can reasonably predict particle removal efficiency.;
