Who Pays for Sewer Line Repair in Utah: Homeowner or City?

Reviewed by Tyler Bennett, Restoration Project Manager, IICRC WRT/ASD #291438, October 2026.

Short answer: In most Utah cities the homeowner is responsible for the private sewer lateral, the line from the house to the city main, and the city maintains the main itself. Where your responsibility ends varies by city, so confirm with your city’s public works department. Insurance usually treats the line repair and the damage inside the home differently, and sewage damage is often covered only with a sewer backup endorsement.

The three parts of the system

• Your building drain: the pipes inside and under the house. Yours.
• Your lateral: the line from the house to the city main. Usually yours, sometimes with the city responsible for part of it near or under the street.
• The city main: the shared line under the street. The city’s.

Signs the problem is your line, not the city’s

• Only your house is backing up, not your neighbors’
• Backups happen in dry weather, not just during storms
• A camera inspection shows roots, a sag or a break in your lateral

If several homes back up during a heavy storm, the city main may be surcharging. See city sewer surcharge after heavy rain.

How insurance usually splits it

• Damage inside the house from a backup: often covered only with a sewer backup endorsement.
• The line repair itself: often not covered by a standard policy; some insurers sell separate service-line coverage.
• Gradual problems like long-term root intrusion: commonly excluded as maintenance.

We review your policy with you before work starts and document the cause for your claim.

Common questions

Who owns the sewer line between my house and the street?

In most cases the homeowner is responsible for the private lateral from the house to the city main, while the city maintains the main itself. Exactly where your responsibility ends varies by city, so check with your city’s public works department.

Will the city pay if its main backed up into my house?

Sometimes a city has a claims process, but do not count on it. Your own homeowners policy with a sewer backup endorsement is usually the first place to look.

Does homeowners insurance pay for sewer line repair?

Many policies treat the pipe repair differently from the damage it caused. Sewage damage inside the home is often covered only with a sewer backup endorsement, and the line repair may not be covered at all. Read your policy or ask your agent.
