The District uses CCTV pipeline inspection as its primary source of information about the existing sanitary sewer collection system. Each pipeline section is TV inspected on a ten-year schedule. Video tapes and written reports document the TV inspection work. Video tapes are stored in the District’s “tape library” until the same area is TV inspected again. Written TV reports are kept in a separate TV inspection notebook. The information obtained by CCTV inspection of pipelines is used to schedule routine maintenance activities such as pipeline cleaning, root sawing, mechanical rodding and chemical foaming of pipelines. Defects, broken pipe and poor side sewer connections are identified and put into the MMIS for future repair projects. TV inspection is also used to identify general deterioration of pipelines and plan for long-range Capital Improvement Projects (CIP) such as pipeline replacement, pipeline lining or pipe bursting projects.
