Watertown is 100 percent sewered, and its sewage runs by gravity to the MWRA system with no pumping stations in the City. When the City main or a house lateral backs up, the lowest drain in the house is where the sewage surfaces.

What does sewage backup cleanup cost in Watertown, MA?

Who to call first
Before hiring a plumber, residents are asked to phone the DPW, which can look at the City main first. Past that point the pipe belongs to the owner, since Watertown holds property owners responsible for their own service laterals. If the main is clear, a plumber clears or repairs the lateral while the crew handles the cleanup, and each step is worth photographing for the claim.
Why sewage is never just dried
Sewage carries bacteria and viruses, so porous materials that touched it, such as carpet, pad, insulation and drywall, are removed instead of saved. Hard surfaces are cleaned and treated with an EPA-registered antimicrobial, and HEPA air scrubbers run while the work goes on so airborne particles do not spread into the rest of the home. Drying starts only after the cleaning is finished.
Preventing the next backup
The City notes that older homes may have deteriorated lateral joints and that roots from large shrubs or trees can break a lateral. Where fixtures can see backflow from a DPW sewer, such as basement floor drains, the City requires a backwater valve and the owner pays for it.

Sewage Backup Cleanup questions in Watertown, MA
Can I clean up a sewage backup myself?
It is not advised. Sewage carries disease-causing organisms, and porous materials must be removed and disposed of properly. Trained crews use protective gear and treat the space.
Does the City or the owner fix the pipe?
The City runs the sewer mains, and owners are responsible for their own service laterals. The DPW can check the main, and a plumber handles the lateral.
Does insurance pay for sewage cleanup?
Many policies cover sewage backup only with an added endorsement. Your own insurer can tell you what applies.
Is it safe to stay in the house?
If the backup is small and sealed off, some households stay. After a larger one, many people leave until cleanup finishes, especially children, older adults and anyone with health conditions.
What is a backwater valve?
It is a fitting on the building drain that closes when sewage tries to flow backward. Watertown requires one on drains liable to backflow.
How long does sewage cleanup take?
Plan on four to seven days of drying after removal and treatment, with readings deciding when the area is cleared.
