Sewer Pipeline & Manhole Rehabilitation

Beginning on or around June 15, 2020, the City’s contractor, National Water Main Cleaning Company (NWM), will rehabilitate existing sewer pipes and manholes in the Davis Square and Teele Square region.

The pipelines within this region of the City were previously inspected in 2018 and 2019, revealing pipeline and manhole deterioration and subsequent infiltration of groundwater into the sewer system. NWM will rehabilitate pipelines and manholes using a combination of methods, including point repairs, cured-in-place liners, root removal, cement lining and sealing of manholes, building manhole benches and inverts, and replacing frames and covers.

Schedule of Work

While all timelines are subject to change, work is anticipated to be completed in December 2020. Daily work hours are approximately 7 a.m. to 4 p.m.

Anticipated Impacts

Streets and sidewalks are expected to remain open for the duration of the project. Lane closures, lane shifts, and parking restrictions may be implemented as needed.

Excavation may produce moderate noise during work hours (typically between 7 a.m. and 4 p.m.) throughout the project area. Crews need to excavate to make point repairs and to access frames and grates in order to rehabilitate manholes.
