The Sewer System Evaluation Survey (SSES), required by the First Amended Consent Decree (FACD), was designed to evaluate the condition of the City’s sanitary sewer system. The SSES program uses various equipment and techniques to detect sewer pipe defects, blockages and capacity problems. Some of these techniques include smoketesting, dye testing, CCTV, flow monitoring, rain monitoring, building service connection and flow isolation. As problems are identified city engineers will determine if the sewer lines and manholes should be repaired or replaced.
