2018 Sanitary Sewer System Evaluation Survey

In 2018, the City of Batesville requested Mendrop Engineering Resources (MER) help the City develop a plan of action to help locate potential infiltration and inflow sources into the sanitary sewer collection system throughout the entire city-wide system. Upon completion of the survey, MER helped develop a plan to rehabilitate the identified problems.

For the sewer system evaluation, MER undertook several different tasks: rainfall monitoring; flow monitoring; sewer TV inspection; manhole inspections; smoke testing; rainfall simulation (dye water testing); property inspections; and flow data analysis. Over 283,000 LF of the system was smoke tested and over 2,000 LF was dye tested. The analysis was used to identify priority areas to use ground penetrating radar to collect data to develop GIS data maps of the infrastructure. All of the collected data and analysis was used to characterize the system and help the City identify and prioritize problems within the existing system.
