Sewer Backup in Columbus, OH

When a sewer line backs up, raw sewage can come up through floor drains, toilets, and basement fixtures. It is Category 3 "black water" that carries bacteria and viruses, so cleanup is a safety job, not just a drying job. We connect you with an independent local restoration or plumbing pro for a free assessment.

Sewer Backup in Columbus: what is different here

Columbus runs a program called Project Dry Basement. If a sewer backup at a single- or two-family home is reported to the city and city staff find it was caused by excess rainwater in the sanitary sewer, the city may provide an approved backflow prevention device. Report a backup right away to the 24-hour Sewer Maintenance Operations Center (614-645-7102) or 311; the city says reports must come within 24 hours so it can determine the cause. Separately, Blueprint Columbus is lining private sewer laterals, redirecting downspouts, and offering sump pumps in project neighborhoods such as Clintonville, Linden, and Hilltop to keep rainwater out of the sanitary sewer.

Columbus is Ohio's largest city, with housing ranging from early-1900s homes in Clintonville, German Village, and the Near East Side to newer subdivisions on the outer belt. The Scioto and Olentangy rivers and Alum Creek run through the metro.

Signs to look for

  • Dark, foul-smelling water coming up through a basement floor drain
  • Toilets, tubs, or the laundry sink gurgling or draining slowly, especially during heavy rain
  • Water backing up in the lowest fixture when you run the washer or flush upstairs
  • Sewer odor in the basement after a storm
  • Neighbors on the same street reporting basement backups at the same time

First steps for Columbus homeowners

  1. Keep children and pets out. Treat the water as contaminated: wear rubber boots and gloves and do not touch your face.
  2. If water is near outlets, appliances, or the electrical panel, stay out and have the power shut off by your utility or an electrician.
  3. Stop adding water to the drains: do not flush, run the washer, or shower until the line is cleared.
  4. Call your city or sewer utility right away, since some programs require a report within 24 hours to decide whether the backup came from the public sewer.
  5. Photograph and video everything before cleanup, and save damaged items for the adjuster if you can do so safely.
  6. Call your insurance agent and ask whether your policy has a water/sewer backup endorsement and what its limit is.
  7. Have a professional remove soaked porous materials (carpet, pad, drywall, insulation) and disinfect. Do not just dry and reuse them.

Contact the City of Columbus Department of Building and Zoning Services (or your suburb's building department) about permits for roof and structural work.

Is there a free sewer backup inspection in Columbus?

Who handles permits in Columbus?

Contact the City of Columbus Department of Building and Zoning Services (or your suburb's building department) about permits for roof and structural work.

Does homeowners insurance cover sewer backup in Ohio?

Usually not unless you added it. The Ohio Department of Insurance lists sewer and drain backup as a typical homeowners exclusion and says the coverage must be added by endorsement. Check your declarations page for a water/sewer backup endorsement and its dollar limit.

Does flood insurance cover sewer backup?

Only in limited cases. FEMA's National Flood Insurance Program covers sewer backup only when it is directly caused by a flood (rising surface water). A backup caused by a clogged or overloaded sewer without a general flood is not a flood claim.

Is sewer backup water dangerous?

Yes. It is Category 3 "black water" under industry cleaning standards and can carry bacteria, viruses, and parasites. The CDC and FEMA advise protective gear and throwing away porous items soaked by sewage.
