Inflow and Infiltration
Every community has to deal with the complicated issue of storm water entering their sanitary sewer system. Whether the issue involves the direct connection of storm water structures (inflow) or groundwater slowly entering defects in the pipes (infiltration), the end result is the same; excessive storm water entering the sanitary sewer system creating backups into basements, overflows into area streams, and overloaded treatment plants. With the EPA now requiring many communities to remove I/I from their systems as part of their NPDES permits, this area of concern has now come to the forefront for many communities.
KEM approaches every I/I study and rehabilitation project in the same manner by focusing on minimizing the costs associated with locating the problems and instead allowing your community's money to go into fixing the problems. The tools that KEM utilizes to find the defects in the sanitary sewer system include: televising sanitary sewers during wet weather to locate defects and potential storm sewer connections, flow monitoring and sewer system modeling to pinpoint problem areas and to ensure that recommended improvements will meet the projects goals, and smoke and dye testing to identify specific sources of inflow and infiltration.
