The City of Indianapolis Department of Public Works (DPW) constructed eleven real-time controls (RTC) in the operation of the collection system between 1995 and 2004 to reduce combined sewer overflows (CSO). These eleven RTC facilities are part of the Early Action Projects (EAP) to reduce CSO frequency and volume. In 2009, DPW completed a hydraulic performance evaluation of each RTC facility using a computer hydraulic model simulation of RTC operations, and successfully quantified their environmental benefits in CSO volume reduction. This evaluation helped DPW to demonstrate the feasibility of utilizing RTC in the collection system to reduce CSOs. This evaluation of the RTC facilities provided a basis
for DPW to further investigate additional CSO control projects that can utilize RTC. This technical paper provides a case study on quantifying the environmental benefits of RTC in a large sewer collection system.
