Can I Get Sick From Cleaning up a Sewer Backup?
Last updated October 25, 2026
The short answer
Health Risks in Sewage
Sewage carries pathogens like E. Coli, hepatitis A, and norovirus. Direct contact with contaminated water or surfaces can spread these germs to your eyes, mouth, or open cuts. Inhaling fine droplets from splashing or drying waste can irritate your airways and lead to coughing or flu-like symptoms.
The longer sewage sits, the more bacteria multiply. Warm, humid conditions in a place like Rockwall can speed that growth. Porous materials such as drywall, carpet, and upholstery soak up contamination, making thorough cleaning and drying essential to reduce lingering health risks.
- Wear rubber gloves, waterproof boots, and eye protection
- Use an N95 mask or respirator to avoid inhaling particles
- Keep children and pets away from the affected area
- Wash your hands with soap and clean water after any contact
- Do not eat, drink, or touch your face while cleaning
When to See a Doctor
If you feel unwell after cleaning, see a doctor. Symptoms like nausea, vomiting, diarrhea, fever, or skin rashes can signal an infection. Tell the doctor about your exposure to sewage so they can offer the right care.
People with weakened immune systems, pregnant women, older adults, and young children face higher risk. For them, even brief contact can be dangerous. If you or someone in your household falls into those groups, it is wise to avoid the cleanup and let trained pros handle it.
Professional Cleanup Approach
Local water damage pros use industrial-grade disinfectants and equipment to clean sewage spills. They typically remove contaminated materials, wash surfaces with hot water and sanitizers, and dry the area thoroughly. This process helps stop germs from spreading further.
The pros also have protective gear and training to handle hazardous waste safely. They know how to dispose of contaminated items properly and can treat hidden areas like crawlspaces or behind walls. For a sewer backup, hiring help often reduces your exposure to harmful pathogens.
- Removing soaked carpets and padding
- Cleaning and sanitizing hard surfaces
- Drying the area with dehumidifiers and air movers
- Disposing of contaminated waste according to local rules
Drying and Sanitizing Steps
After the bulk of sewage is removed, the space must be cleaned and dried. Use a disinfectant that kills bacteria and viruses, following the label instructions for contact time. Then run fans, dehumidifiers, or open windows to lower moisture levels.
In a humid climate like Rockwall, drying can take longer. If you attempt it yourself, monitor the area for lingering odors or dampness. If mold begins to grow, that adds another health concern. Thorough drying is key to preventing secondary problems.
Protecting Your Home Long Term
Once the cleanup is done, consider what caused the backup. A plumber can inspect your sewer line for clogs or damage. If tree roots or pipe issues are found, fixing them can reduce the chance of a repeat event.
Check your insurance policy to see if sewage backup damage is covered. Policies vary, and your insurer decides what is covered. Keep records of the damage and cleanup steps for your claim. Acting quickly helps limit health risks and property damage.

How long does sewage contamination stay dangerous?
Pathogens can survive on surfaces for days or weeks, especially in damp conditions. Drying and disinfecting reduce the risk, but porous materials may need to be removed. If you are unsure, treat the area as contaminated until properly cleaned.
Can I clean a small sewer backup myself?
For very small spills, you can try with proper gear and disinfectants. But the risk of missing hidden contamination is real. If the area is large, or you feel uncomfortable, call the pros to handle it safely.
What should I throw away after a sewer backup?
Throw away anything porous that touched sewage, like carpets, drywall, mattresses, and upholstered furniture. Non-porous items like metal or plastic can be cleaned and disinfected. When in doubt, discard it to avoid health risks.
