Inflow and Infiltration <br /> Inflow and infiltration occur when clear water gets into the sanitary sewer system. This <br /> may occur through cracks or leaks in the sewer pipes and manholes or through sump <br /> pumps incorrectly connected to the sanitary sewer system. Inflow and infiltration can <br /> lead to backups, overflows and unnecessary and expensive treatment of clear water. <br /> City employees will periodically inspect manholes to identify any that contribute to this <br /> problem. Sanitary sewer mains will be maintained and inspected pursuant to the City's <br /> Sanitary Sewer Maintenance Policy. <br /> 4. Personnel Responsibilities and Requirements <br /> K.
