Somerville's compact neighborhoods and aging sewer infrastructure make it one of the most backup-prone communities in Greater Boston. The city's sewer system includes sections of combined sewers that carry both sanitary waste and stormwater, and during heavy rain events, these systems can overwhelm residential lateral connections and force sewage back into basements. Winter Hill, Ball Square, and Magoun Square sit on older sewer mains dating to the early 1900s that are smaller in diameter than modern standards, further limiting capacity. The dense tree coverage along residential streets in Teele Square and West Somerville sends roots aggressively into clay sewer laterals, a problem compounded by the fact that many Somerville lots are so narrow that sewer lines run close to property-line trees planted by neighbors. Somerville's ongoing sewer separation project, one of the largest municipal infrastructure investments in the city's history, is gradually reducing combined sewer overflows but will take years to complete. In the meantime, homeowners in affected neighborhoods should consider installing backwater prevention valves and scheduling annual sewer line maintenance cleanings.
Somerville by the numbers
Somerville's sewer separation project, which began in 2012, has reduced combined sewer overflow events by approximately 30%, but affected neighborhoods still experience backup risks during storms exceeding 1.5 inches of rainfall per hour.
Sewer clearing in Somerville costs $300 to $600. The city's narrow lots and tight building spacing can make sewer access more challenging, and full lateral replacement typically runs $5,000 to $14,000 due to the complexity of excavating in compact urban yards.
Find the shut-off valve nearest to the problem and turn it clockwise. If you cannot locate it, shut off the main water supply to your home.
Use towels, buckets, and a wet vacuum to contain any standing water. Move electronics and valuables away from the affected area.
Take photos and videos of the damage before cleanup begins. This documentation is crucial for insurance claims.
