Sewer Pipeline & Manhole Rehabilitation

Somerville’s over 180 miles of sewer pipelines are a critical asset to our community that residents and businesses rely upon daily. Just like any other infrastructure or equipment, our sewers require regular upkeep and rehabilitation in order to function effectively. 

Each year the City’s Department of Infrastructure and Asset Management sets out to repair deficiencies identified in the previous year’s Annual Sewer and Storm Drain Inspection Program

How It Works

Each year the City inspects a portion of our sewer and drainage system to identify areas in need of rehabilitation. While more critical issues are addressed via emergency repairs, regular rehab and maintenance typically takes place the following year through our Sewer Pipeline and Manhole Rehabilitation Program.

Pipelines and manholes are rehabilitated using a combination of methods, including but not limited to the following: 

  • Injection Grouting – acrylic grout is pressure injected through a defect in the pipe, forming an impermeable barrier
  • Cured In Place Pipe (CIPP) Lining – a flexible liner is inserted inside the existing pipe, inflated, and then hardened, forming a smooth surface inside the existing pipe
  • Open Trench Excavation – crews will dig down to and expose existing pipe, remove the defective section or full length of pipe, and then install new pipe
  • Spot Repair – similar to Open Trench Excavation, crews will dig a small trench, remove a short section of pipe, and install a new section of pipe
  • Manhole Lining & Sealing – epoxy or cementitious material is applied to the inside of the manhole as a coating, restoring structural integrity and waterproofing the manhole


When excavation is required for construction, City contractors will pave the impacted area with a temporary course of asphalt immediately following the work. They will then return roughly a year later and perform final surface restoration.

Schedule of Work

This work is expected to begin in late May and continue through the summer. Residents will receive additional notification prior to work beginning on their street.  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. Driveway access will be maintained.

Excavation may generate moderate noise during work hours (typically between 7 a.m. and 4 p.m.) throughout the project area. Pipe lining may produce a bubblegum-like odor that will dissipate quickly once the process is complete.


Stay Informed

Residents in impacted areas will receive notification via flyers and community alerts prior to work starting in their area. 

Sign up for the City alert system to receive notifications about disruptive construction, snow emergencies, and major events planned for your neighborhood: somervillema.gov/alerts
