Sewage Backup: Health Hazards and Cleanup

A sewage backup is one of the most hazardous situations a homeowner can face. Unlike clean water damage, sewage contains dangerous pathogens that pose immediate health risks. Understanding these hazards underscores why professional cleanup is not optional.

What's in Sewage

Raw sewage contains bacteria (E. coli, Salmonella, Shigella), viruses (Hepatitis A, Rotavirus, Norovirus), parasites (Giardia, Cryptosporidium), fungi and mold spores, and chemical contaminants. Exposure to these pathogens can cause severe gastrointestinal illness, skin infections, respiratory problems, and in rare cases, life-threatening conditions.

Immediate Health Precautions

If sewage backs up into your home, evacuate all occupants, especially children, elderly, and immunocompromised individuals. Do not touch sewage water or contaminated materials without protective equipment. Do not eat food that has contacted sewage water. Do not use contaminated water for any purpose. Keep children and pets away from affected areas.

Why Professional Cleanup Is Essential

Sewage cleanup requires specialized equipment, EPA-registered disinfectants, and strict safety protocols. Professionals wear full personal protective equipment including respirators. All contaminated porous materials (carpet, padding, drywall, insulation) must be removed and disposed of according to regulations. Remaining surfaces require thorough disinfection.

The Cleanup Process

Professional sewage cleanup involves safety assessment and hazard containment, sewage extraction using specialized pumps, removal of all contaminated porous materials, disinfection of all remaining surfaces with EPA-registered antimicrobials, structural drying with commercial dehumidifiers, air quality testing to verify safety, and restoration of removed materials.

Insurance Coverage

Many homeowner's policies cover sewage backup damage if you have a sewer backup endorsement (sometimes called water backup coverage). This is an add-on to standard policies and is highly recommended. Check your policy and consider adding this coverage if you don't have it.
