Owner - Town of Speedway, IN

Developed two XPSWMM models for the separation of two combined sewer areas in the Town of Speedway, IN.  Assisted the Town in locating new flow meters for calibration purposes and conducted calibration of the XPSWMM models using flow meter and rain gauge data.  Modeled the effects on the combined sewer system using the IDEM 1-year 1-hour storm and 10-year 1-hour storm and modeled separation alternatives for the combined areas.  Determined the size of the new storm sewers, underground detention pond, and best management practice (BMP) measures for storm water quality and evaluated the flows in the receiving creek.  Prepared a report of the existing system which outlined the proposed separation alternatives, pipe sizes, detention pond, and BMP’s.
