  • ENTITY TYPE: City/Township

The document provides detailed information about pipe cleaning and Cured-In-Place Pipe (CIPP) specifications for the rehabilitation of sewer and storm water pipes. The document states that the firm is responsible for cleaning the interior of the sewer main and storm drain to allow for internal video inspection. The cleaned pipe should be restored to at least 95% of its capacity. The firm is also responsible for hauling and disposing of all debris removed during the cleaning process. Excessive amounts of grease may not be accepted, and if encountered, the City of Salisbury Water & Sewer Branch Superintendent should be contacted. Precautions should be taken to prevent damage or flooding of public and private property during the cleaning process. Water will be available from a designated fill station at the City Service Center. The cleaning equipment should consist of high-velocity jet hydro cleaning equipment with specific capabilities and should carry its own water tank, auxiliary engines, pumps, and hydraulically driven hose reel. Regarding CIPP specifications, the document specifies the use of a Cured-In-Place Pipe (CIPP) liner for the rehabilitation of sewer and storm water pipes. The specification includes quality control measures to ensure consistent and high-quality CIPP liners. The specification is open to both fiberglass-based CIPP products cured with ultra-violet light and felt-based CIPP products cured with hot water. However, steam-cured CIPP products are not included due to the lack of reliable quality control procedures. The document provides a general description of the CIPP rehabilitation process, including cleaning, identification of existing live taps, point repairs, installation of a resin-impregnated tube, curing, reopening service taps, sampling and testing, and clean-up. The contractor's experience record and reference standards are also mentioned. The document emphasizes the responsibility of the contractor for containment of sewage, site cleanliness, and spill cleanup. The project will be bid on a "price per lineal foot" basis, and the Owner will verify the Contractor's measurements for payment purposes.
