The short answer
The Pathogens in Sewage
Sewage contains a concentrated mix of pathogens expelled from the human body. Common bacteria like E. Coli and Salmonella are often present, alongside viruses such as norovirus and hepatitis A. These organisms thrive in the nutrient-rich environment of wastewater, and even a small exposure can lead to infection. Touching contaminated surfaces or inhaling airborne particles can transfer these hazards to you and your family.
The risk is not limited to visible contact. Pathogens can be aerosolized during cleaning or remain on porous materials long after the water recedes. This makes do-it-yourself cleanup particularly dangerous without proper protective equipment and cleaning agents. Porous items like carpets or drywall can harbor these microbes, creating an ongoing source of contamination in your living space.
Immediate Health Risks
Direct contact with sewage backup can lead to gastrointestinal illness, characterized by vomiting, diarrhea, and cramping. Open cuts or wounds exposed to contaminated water risk serious skin infections or even blood poisoning. Inhaling airborne droplets or dust from dried sewage can also cause respiratory issues, especially for those with asthma or weakened immune systems.
Children, the elderly, and anyone with pre-existing health conditions face the greatest danger from these exposures. Symptoms might not appear immediately, allowing infections to take hold. If you or a family member experiences fever, nausea, or persistent coughing after an incident, you should see a doctor promptly to discuss potential exposure.
- Gastrointestinal infections from bacteria and viruses.
- Skin infections and rashes from direct contact.
- Respiratory problems from inhaling contaminated aerosols.
- Hepatitis and other viral diseases.
- Parasitic infections from organisms like Giardia.
- Increased risk for those with compromised immunity.
Secondary Damage and Mold
Beyond the initial biohazard, sewage water creates perfect conditions for mold to grow. Mold spores are everywhere, and the organic material in sewage provides ample food. In a humid subtropical climate with hot summers and spring hailstorms, like in many areas, high indoor humidity can accelerate this growth within 24 to 48 hours.
Mold growth adds another layer of health concerns, particularly for respiratory systems. It can damage building materials, requiring more extensive repairs. The combination of pathogens and mold creates a compounded indoor air quality issue that standard cleaning cannot resolve. This secondary damage often makes the overall restoration process more complex and critical.
Why Professional Cleanup Is Essential
Local water damage pros have the training and equipment to treat sewage as a biohazard safely. They use industrial-grade disinfectants and antimicrobial treatments that are not available to consumers. Their process involves containing the area to prevent cross-contamination, removing all contaminated porous materials, and thoroughly sanitizing salvageable surfaces. This systematic approach addresses both visible waste and invisible microbes.
Attempting cleanup yourself puts your health at risk and may leave behind dangerous contaminants. The pros follow established safety protocols, including wearing personal protective equipment like respirators and full-body suits. They also use specialized tools for extraction and drying that prevent further spread of contaminants throughout your home's structure and ventilation system.
Steps to Take After a Sewage Backup
Your first step is to ensure everyone's safety by avoiding contact with the affected area. Turn off electricity to the wet zones if it is safe to reach your breaker panel. Contact a plumber to address the source of the backup, and then call for professional water damage and sanitation help. Ventilate the area if possible by opening windows, but do not use household fans.
Document the damage with photos for a potential insurance claim, but do not disturb the contaminated items. Policies vary, and your insurer decides what is covered. Keep children and pets away from the area entirely. Remember that time is critical; the longer sewage sits, the greater the damage and health risk become.
- Evacuate the affected area immediately.
- Shut off electrical power if safe to do so.
- Call a plumber to stop the flow at its source.
- Contact professionals for biohazard cleanup.
- Avoid using sinks or toilets connected to the blocked line.
- Begin documenting damage for insurance purposes.

Can I clean up a small sewage spill myself?
It is not recommended. Even a small spill contains concentrated pathogens. Without proper protective gear and hospital-grade disinfectants, you risk exposure and incomplete sanitation, which can lead to illness or hidden mold growth later.
What items are usually unsalvageable after sewage damage?
Porous materials that absorb contaminated water are typically discarded. This includes carpet, padding, upholstered furniture, drywall, insulation, and some personal items like mattresses or stuffed toys. Non-porous materials like metal or plastic may be sanitized.
How does sewage backup affect my insurance claim?
Coverage depends heavily on the source of the backup. Sudden, accidental failure of a sewer line may be covered, while flooding or neglect often is not. Policies vary, and your insurer decides what is covered. Review your policy details carefully.
