2021 CIPP Lining Program

The scheduled work 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 lines. The City is currently compiling a list of pipelines to be assessed for lining; and it is estimated for bidding purposes that approximately 74,700 linear feet of sewer lines 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 32,550 linear feet of sewer lines of various sizes will be CIPP lined. The actual work effort, however, may be less or more than the estimated quantities in the Bid Form. The work also includes sewer manhole rehabilitation, and other appurtenant items.
