The short answer
Health Risks from Sewage Exposure
Sewage carries a mix of harmful microorganisms, including E. Coli, salmonella, hepatitis A, and norovirus. When these pathogens enter your body through your mouth, nose, eyes, or an open cut, they can trigger symptoms like diarrhea, vomiting, fever, and stomach cramps. Some infections, such as hepatitis A, can cause long-term liver issues, so taking the situation seriously matters.
Breathing in contaminated mist or dust can also irritate your lungs, leading to coughing or wheezing, especially if you have asthma or a weakened immune system. Skin contact with sewage can cause rashes or infections, particularly if you have any scratches or sores. The longer you stay in the affected area without protection, the greater your risk of becoming ill.
- Wear rubber boots and waterproof gloves
- Use an N95 mask to avoid inhaling particles
- Keep children and pets away from the area
- Wash any exposed skin with soap and clean water
- Do not eat or drink near the affected space
- See a doctor if you feel unwell after exposure
How Long Until Symptoms Appear
Symptoms from sewage-related illnesses can appear within a few hours or take several days to develop, depending on the specific pathogen and how much you were exposed. For example, norovirus often causes symptoms within 12 to 48 hours, while hepatitis A has an incubation period of two to six weeks. Because of this variability, you might not connect your illness to the backup right away.
If you develop diarrhea, vomiting, or a fever after a sewage backup, stay hydrated and monitor your condition. Severe symptoms like bloody stools, high fever, or signs of dehydration require prompt medical attention. Mention the sewage exposure to your doctor, as it can help them identify the likely cause and recommend the right treatment.
Protecting Yourself During Cleanup
Your safety comes first when dealing with sewage. Before you start any cleanup, put on protective gear, including heavy-duty gloves, boots, and eye protection. A mask that filters particles is also wise, since sewage can create airborne droplets. Ventilate the space by opening windows and doors to reduce the concentration of harmful substances.
Avoid direct contact with contaminated items and water. Do not turn on air conditioning or heating, as that can spread contaminants through the house. If you have any open wounds, cover them with waterproof bandages before entering the area. After cleanup, remove and wash your clothes separately in hot water, and shower thoroughly with soap.
When to Call the Pros
Sewage cleanup involves more than just wiping surfaces. Porous materials like drywall, carpet, and upholstery can absorb contaminants and need professional handling or removal. Local water damage pros have the equipment and training to safely extract sewage, disinfect the area, and dry it thoroughly, reducing the chance of mold growth.
If the backup is large, or if you have health concerns, it is wise to let the pros handle the job. They can also assess hidden damage, such as in wall cavities or under flooring, that you might not see. Attempting a major cleanup yourself can put you at risk and leave behind harmful residues that continue to affect your health.
- Large or heavily contaminated areas
- Sewage has soaked into drywall or carpet
- You have a weakened immune system
- The odor persists after basic cleaning
- You are unsure about the extent of the damage
Preventing Future Backups
After the immediate cleanup, focus on preventing another backup. Common causes include clogs in the main sewer line, tree root intrusion, or a failure in the municipal sewer system. Regular maintenance, like not pouring grease down drains and flushing only toilet paper, can reduce the risk. If you live in Mesa, keep your shutoff valve location written down in case of an emergency.
Consider installing a backwater valve to prevent sewage from flowing back into your home during heavy rains or municipal overflows. Also, have a plumber inspect your sewer line periodically, especially if you have older pipes or large trees nearby. Taking these steps can save you from the health risks and mess of a future backup.

How long does it take to get sick after a sewer backup?
Symptoms can appear within a few hours or take up to a few weeks, depending on the pathogen. Norovirus often hits within 12 to 48 hours, while hepatitis A can take two to six weeks. If you feel ill, see a doctor and mention the sewage exposure.
Can a sewer backup cause a skin infection?
Yes, sewage contains bacteria that can cause skin infections if it contacts cuts, scrapes, or even intact skin for a long time. Rashes and infections are possible. Always wear gloves and boots, wash any exposed skin with soap and water, and cover open wounds.
Should I clean up sewage myself or hire a professional?
For small spills, you can clean with proper gear and disinfectants. But for large backups or porous materials like drywall, it is safer and more effective to call local water damage pros. They have the right equipment and training to handle hazardous waste.
