Who pays for sewer line repair?

Two descriptions, and why that matters

Citizens Energy Group’s homeowner-facing guidance on connecting a sewer service line describes the owner as maintaining the lateral from the home to the main. Its formal wastewater service terms describe the arrangement in more granular language, distinguishing a utility-maintained portion from the main up to a boundary from a customer-maintained portion running from that boundary to the premises.

Citizens’ public materials describe this at different levels of detail, so do not infer from either statement which one controls a specific address. Ask Citizens to confirm the current boundary and responsibility determination for your address and the located defect before excavation, and retain any reference or case details you are given.

Locate the defect before arguing about it

A responsibility conversation without a distance measurement goes nowhere. What you need is an inspection that records how far from the access point the defect sits, a surface locate marking that point in the yard or street, and photographs or footage you can share. With those, the question becomes concrete: this defect is at 58 feet, which lands beyond the property line — whose is it?

Our inspection guide covers what that deliverable should include.

Permit responsibility is not financial responsibility

These get conflated constantly. Citizens’ guidance describes exterior sewer service line work as requiring a qualified contractor, a permit and an inspection — that is a process obligation attached to the work. Who ultimately bears the cost of a given repair is a separate question determined by where the failure is and which portion it falls in. A contractor can be entirely correct about the permit requirement and still be assuming the wrong answer about the bill.

Contractor or utility?

If the evidence points to the public system, report it to the utility and let them investigate before authorizing private work. If it points to your portion, the work is yours to arrange with a qualified contractor, permitted and inspected. Where the defect sits ambiguously near the boundary, get the location documented and ask Citizens to confirm the current boundary and responsibility before excavation, and retain any reference or case details they provide. Backfilling first and asking later removes the evidence.

Insurance: two separate questions

Damage inside the home caused by a backup is one coverage question. The Indiana Department of Insurance notes that sewer and drain backup is commonly excluded from standard homeowner policies and may be available as an endorsement. Failure of the buried service line itself is a different coverage question. Review your policy declarations and endorsements and ask your carrier whether the specific cause and the buried service line are covered, rather than asking generally whether “sewer problems” are covered.

Before you authorize anything

Get the defect located and documented. Confirm the governing boundary for your address. Report anything that may involve the public system. Call your insurer. Then, and only then, obtain written scopes — see the cost guide for making them comparable.
