Sewage Backup Cleanup

Sewage backups bring Category 3 black water into the home. Cleanup needs protective gear, removal of porous materials and full sanitizing before drying and rebuilding.

Sewage backup cleanup is the removal of wastewater that backed up through toilets, tubs or floor drains, followed by disposal of contaminated materials, disinfection and drying. Sewage is Category 3 black water under the IICRC S500 standard and can carry bacteria and viruses.

Quick answer

Keep people and pets away, stop using sinks, toilets and appliances that drain into the line, and call for professional cleanup. Do not try to save carpet, pad or upholstery touched by sewage.

Why sewers back up

  • Tree roots growing into the sewer lateral.
  • Grease, wipes and debris clogging the line.
  • Heavy rain overloading city sewers.
  • Collapsed or sagging old pipes.

What cleanup includes

  1. Crews wear protective suits, gloves and respirators.
  2. Sewage is extracted and solids are removed.
  3. Carpet, pad, insulation and lower drywall touched by sewage are bagged and removed.
  4. Hard surfaces and framing are cleaned and disinfected.
  5. The area is dried with air movers and dehumidifiers and checked before repairs.
Health note: wash hands well after any contact, and keep children, pregnant people and anyone with a weak immune system out of the area until cleanup is done.

A plumber should clear or repair the line so it does not back up again. A backwater valve can help prevent future backups. Coverage usually needs a sewer backup endorsement; see the insurance guide.
