Phase 1 of the Sewer Division's Capacity, Management, Operation and Maintenance (CMOM) pipeline and manhole inspection program began in July 2022 and was completed in the Fall of 2022. As part of the Phase 1 CMOM inspection program, the Town inspected approximately one-third (1/3) of all the pipelines and manholes within the municipal sewer collection system. Town staff worked in conjunction with our consultant, Environmental Partners Group, to manage this comprehensive sewer system inspection program. National Water Main Cleaning Company performed CCTV video inspection of approximately 20 miles of sewers in the downtown area of Plymouth. Duke's Root Control performed 3D digital scanning of approximately 500 sewer manholes in the downtown area.
