1. I/N TEK Line and I/N Kote Line Evaluation <br />Background: <br />South Bend manages flows coming from auxiliary sewer lines from New Carlisle, IN. The I/N TEK <br />line is separated and enters the combined section of the system on the West side of the City. The <br />I/N Kote line is a newer sewer that's completely separated and flows directly to the wastewater <br />plant. Originally, the plan was to send the total flow from these large industrial users through the <br />separated sanitary sewer to the greatest possible extent to protect the river from industrial waste <br />during wet weather events. <br />This project aims to better control and characterize how to control the flows through these two <br />lines to better control them during varying weather events. Focus will be given towards identifying <br />opportunities to store flow during wet weather, while accelerating or redirecting flows during dry <br />events. Recommendations will be provided to City staff as to how to enhance the management <br />of these lines across a variety of weather conditions using existing control points. <br />Objective: <br />Review and study the I/N TEK and Kote lines to better characterize their contributions to the South <br />Bend collections system. Identify inline storage opportunities and perform data evaluation to <br />determine if and how this line could be strategically leveraged within the wider collections network <br />to protect the St. Joseph River. <br />Tasks: <br />A. Obtain and evaluate meter data along the I/N TEK and Kote lines, as available <br />B. Obtain and evaluate hydraulic models for both lines <br />C. Evaluate and identify inline storage opportunities in the 2 lines to retain and accelerate <br />flows during wet weather <br />D. Identify possible sources of odor at lift stations and provide recommendations to mitigate <br />or eliminate odor sources <br />Deliverables: <br />Report detailing model evaluation, flow meter data, possible inline storage control points, and <br />sources of and methods to alleviate lift station odor challenges. <br />e net 121 S.
