2022 CIPP Lining

The scheduled work for the 2022 CIPP Lining Project consists of pipeline cleaning and video assessment, followed by cure-in-place pipe (CIPP) lining of sewers on various residential and arterial streets in Nashua. The pipelines to be CIPP lined will be determined based on a review of the initial cleaning and CCTV video of various sewer mains and catch basin laterals. The City is currently compiling a list of pipelines to be assessed for lining; and it is estimated for bidding purposes that approximately 65,500 linear feet of sewer mains and 7,500 linear feet of catch basin laterals will be initially cleaned and videoed. As the initial video assessments are submitted, the City will review the video and select pipes to be CIPP lined. It is estimated for bidding purposes that approximately 18,000 linear feet of sewer mains of various sizes will be CIPP lined; and 1,000 linear feet of catch basin laterals will be CIPP lined. The work also includes sewer manhole rehabilitation, and other appurtenant items of work.
