The short answer
Health Risks from Sewage Exposure
Sewage contains a dangerous mix of pathogens from human waste, including E. Coli, hepatitis, and norovirus. Direct contact or even breathing contaminated air can lead to serious gastrointestinal illnesses, skin infections, and respiratory problems. Children, elderly individuals, and anyone with a compromised immune system are at higher risk. For your safety, treat all sewage as a biohazard.
If you have any contact with sewage water, wash thoroughly with soap and clean water immediately. Keep children and pets far away from the affected area. Watch for symptoms like nausea, fever, or diarrhea, and see a doctor if you feel unwell. The pros use industrial-grade disinfectants and personal protective equipment to manage these hazards.
What Professional Cleanup Involves
Local water damage pros follow a strict protocol for sewage backup cleanup and sanitation. The process starts with removing the contaminated water using submersible pumps and industrial extractors. They then take out any porous materials that cannot be salvaged, such as soaked drywall, carpet padding, and insulation. These items must be bagged and disposed of as regulated waste.
The remaining structure and contents undergo a thorough cleaning with hospital-grade antimicrobial solutions. Powerful air movers and dehumidifiers then dry everything completely to prevent mold growth. The pros also treat the air with specialized equipment to remove odors and airborne contaminants. This comprehensive approach is designed to make your home safe again.
- Complete removal of contaminated water and waste.
- Safe disposal of unsalvageable porous materials.
- Deep cleaning with EPA-registered disinfectants.
- Structural drying to prevent hidden moisture.
- Air scrubbing to remove odors and pathogens.
- Verification of a safe, dry environment.
When You Might Handle a Small Incident
For a very minor incident, like a small toilet overflow from clear water, you might choose to clean it yourself. This only applies if the water is clean and contained to a small, non-porous surface. You must still wear gloves, eye protection, and a mask. Use a bleach solution to disinfect the area, and ensure it dries completely to avoid mold.
Any event involving water from a drain, washing machine, or dishwasher is considered greywater and carries some risk. Water from a toilet bowl or sewage line is blackwater and is always hazardous. If you are unsure of the water category, err on the side of caution and call for help. The potential cost of improper cleanup is far greater than the initial service call.
Insurance and Sewage Backup Claims
Many homeowner insurance policies do not automatically cover damage from a sewer backup. You often need a specific sewer backup endorsement added to your policy. The cost for professional sewage cleanup can range widely, often from several thousand dollars to much more, depending on the extent of damage and affected materials. Policies vary, and your insurer decides what is covered.
If you have coverage, document the damage thoroughly with photos and notes before any cleanup begins. Keep records of all damaged items. Contact your insurance company promptly to start the claims process. They will guide you on their required steps, which usually include getting an assessment from the pros.
What You Can Do While Waiting for Professionals
Your first priority is safety. Turn off the electricity at the main breaker if water has reached outlets or electrical fixtures. Avoid using your home's plumbing fixtures to prevent adding more water to the backup. If you know the source, like a blocked main line, you can call a plumber. Ventilate the area by opening windows if it is safe to do so.
Move undamaged furniture and belongings to a dry area. Do not attempt to salvage heavily contaminated items like stuffed toys or mattresses. Keep people out of the affected space to limit cross-contamination. Your actions can help minimize secondary damage, but leave the actual sewage removal and disinfection to the pros.
- Ensure electrical safety by shutting off power.
- Stop using all drains and toilets.
- Keep people and pets out of the affected space.
- Open windows for ventilation if possible.
- Move dry, valuable items to safety.
- Document the damage with photographs.

What makes sewage so dangerous?
Sewage contains human waste, which carries bacteria, viruses, and parasites. These pathogens can cause severe illnesses like gastroenteritis, hepatitis, and skin infections. Even after the water is gone, contaminants can linger on surfaces and in the air.
Will my homeowner's insurance cover this?
Coverage for sewage backup is not standard in most policies. You typically need a specific endorsement or rider. Policies vary, and your insurer decides what is covered. Check your policy details and call your agent to understand your coverage.
Can sewage cause mold growth later?
Yes. If the moisture from a sewage event is not completely removed, mold can begin growing within 24 to 48 hours. Professional drying is crucial to prevent this secondary damage, which creates another health hazard and repair cost.
