Waltham's older sewer laterals
Pre-1980 housing here is 70%, close to the Massachusetts figure of 68%. That ranks 13th lowest of the 37 Massachusetts cities we profile. Clay pipe lets roots in at the joints, cast iron scales and cracks, and the line from the house to the street belongs to the homeowner in most places.
Only 37% of homes are single-family detached, so many sewer problems involve a shared building line. Check with your HOA or landlord before booking work.
In Massachusetts: Long winters make frozen pipes a regular emergency.
Permits
Excavation in the yard or street needs a permit, and someone has to call 811 first to get utilities marked.
