Abstract:

The City of South Bend, IN is implementing an innovative real time control system that will better utilize the City's existing conveyance and treatment capacities. City has automated nine of its CSO regulators, which will allow the collection system to adapt itself in response to the inherent variability of rainfall. The result is that flow that would have normally overflowed is now able to be treated at the WWTP. The City has successfully completed manual test exercises during an actual storm event and is in the process of fully automating the control valves. Once the system is fully implemented, it is expected that it will reduce the City's annual overflow volume by over 200 MG, or 23%, simply by better utilizing the City's existing pipes.
