Do this now: sewage backup or a broken line

1. Stop using water in the house: no flushing, laundry or dishwasher.
2. Call 311. KC Water inspects and cleans the public main for a property with backups.
3. Keep people and pets away from sewage, and shut off power to a wet basement only from a dry spot.
4. Photograph the damage and call your insurer to ask whether your policy includes sewer backup coverage.
5. For cleanup, see water damage restoration in Kansas City.

Is it urgent? Signs the sewer line has failed

A sewer line is urgent when sewage backs up into the house, several drains gurgle or back up at once, or a wet, smelly spot appears in the yard. One slow drain usually is not a broken line. Check the City main first: KC Water inspects and cleans the public main when you report a backup to 311. If the main is clear, the problem is your line, and Angi's Kansas City emergency guide lists $1,230 to $4,630 to clear a main line clog after hours. Daytime cleaning is on drain cleaning in Kansas City.

Who owns the sewer line in Kansas City

The property owner does, from the main to the building. KC Water's Rules and Regulations for Sewer Service Lines (Section 3.06) say "the property owner shall maintain all service lines from the main to the building," and KC Water maintains the public mains. There is one exception: for a defective private residential line in the City right of way or an easement, such as a 100% blockage or a no-relief situation, the KC Water Director or a designee may authorize repair or replacement. The cost split is not stated. Your plumber schedules a location check with KC Water Investigations and Inspections at 816-513-4810, using your 311 case number.

Permits and inspections for sewer work in Kansas City

Digging in the street needs a KC Water permit. The rules say a KC Water Repair Permit is required to alter, repair or renew a service line between the main and the property line, and work on private property outside the right of way is permitted by City Planning and Development. Every new sewer service line and repair must be inspected. KC Water's FY27 Rate Book lets the director charge $100 for each permit for taps, new service installations and alterations to existing services. Ask whether the plumber's price includes both permits.

Repair, replace or go trenchless

A camera inspection shows whether one section is broken or the whole line is failing. HomeGuide prices sewer line repair at $150 to $3,800 nationally, depending on the method, and replacement at $50 to $250 per foot. This Old House puts an average replacement at $3,320. Triple-I says small roots seeking moisture work into cracks and later cause blockages or major damage, and old lines have more cracks: the Census Bureau counts 63.1% of Kansas City's housing units as built before 1980, with a median of 1969. The City's Targeted Minor Home Repair Program includes sewer mains and drain lines for eligible owner-occupants in 9 named neighborhoods. Methods compared: sewer line repair.
