Track: Water, Wastewater, and Stormwater
Authors: Aimei Chen, Randy Schneider, Michael Stevens

Metropolitan Sewer District of Greater Cincinnati maintains and operates approximately 3000 miles of sewer pipes with various sizes, types and materials. To provide efficient service to our citizens,
MSD Risk Team developed a Gravity Sewer Criticality Matrix by using Model Builder based on our existing geographical information system. We'll use this tool to better manage our assets more pro-actively by prioritizing and address the most critical or at-risk sewers in the system first.
