State guide
Connecticut
Connecticut does not have a single statewide sewer-lateral ownership statute for ordinary municipal laterals, so residents usually have to look at local WPCA or utility rules. The official local pages reviewed for Middletown and Meriden put the building sewer/lateral on the property owner from the municipal main to the building, while the state licensing and permit materials treat this as plumbing work done from the point of utility responsibility toward the structure.

- Who usually owns the sewer lateral
- Usually the property owner is responsible for the full building sewer/lateral to the municipal main, including the street connection, unless local rules say otherwise.
- State agency
- Connecticut Department of Consumer Protection for plumbing licensing, plus the local WPCA or water/sewer department for municipal permits and ownership rules.
- Permits for repair or replacement
- State materials show sewer-line work is plumbing work, and local pages reviewed require permits for sewer lateral repair, replacement, reconnection, or new connection work.
- Inspection at sale
- Connecticut's seller disclosure asks about public sewer and known testing or inspection, but the statute also says the seller is not required to secure inspections or tests.
- Assistance programs
- No Connecticut state sewer-lateral grant program was found on the official pages reviewed, but Connecticut Water offers optional Linebacker warranty plans that can cover certain wastewater-line repairs.
