Combined sewer systems often consist of complex diversion structures to convey a wide range of wet weather events. In this FLOW-3D HYDRO simulation, a hinged flap gate allows flow to enter the sanitary sewer main during a storm event. As the flow increases, it eventually discharges over a weir and overflows from the structure to provide hydraulic relief to the sewer system. Understanding the flow distribution between the main sanitary sewer and overflow is very important when trying to optimize the system to minimize sewer overflows to the environment. 3D CFD modeling provides detailed insights into these structures by accounting for more detailed hydraulic losses, which can then be used to fine tune your system-wide sewer network modeling.
