Abstract Details

2022, Master of Science in Engineering, University of Akron, Civil Engineering.
The City of Akron operates a collection system that consists of sanitary and combined sewers. When originally designed and constructed around a century ago, the combined sewers were intended to overflow during wet weather events to local waterways. That practice is no longer acceptable, and the City is now under a Consent Decree with the U.S. EPA to eliminate overflows for a typical year of rainfall at all combined sewer overflow locations. The Ohio Canal Interceptor Tunnel (OCIT) was designed to overflow three times, but that overflow needs to be treated. In order to optimize the collection system and storage facilities, the City has implemented a Real Time – Decision Support System (RT-DSS). The primary goal of the RT-DSS was to eliminate or reduce the number of overflows that occur at OCIT during the typical year of rainfall. The RT-DSS was installed and began being operational in the summer of 2019, however, OCIT and another storage facility were not online until the summer of 2020. The purpose of this study was to evaluate the observational data collected by the sensors placed in the system that feed the RT-DSS logic and the SCADA that recorded actual operation of the system and RT-DSS dewatering recommendations after a wet weather event had occurred. A spreadsheet tool was developed to analyze the collected data and evaluate whether or on the City operators followed the RT-DSS dewatering recommendations and if they did not, who would have operated the system more efficiently – the operators or the RT-DSS. The results indicate that during small wet weather events, less than or equal to a typical year event, the operators generally follow the RT-DSS logic and no overflows occur at the storage facilities. Finally, a scorecard was produced that evaluated each wet weather event based on the amount of rainfall, overflow volumes at key storage facilities, plant flow, and operation to help refine the logic in the RT-DSS. This scorecard provides a means for evaluating future events, as well as building out a framework to adjust the scoring system as needed.
