A sewage backup is not just unpleasant. It is a biohazard. The IICRC classifies sewage as Category 3 water, the most contaminated level, because it can carry bacteria, viruses, and parasites. Here is how to respond safely.

Health Risks of Sewage Exposure

  • Bacteria such as E. coli and Salmonella
  • Viruses including hepatitis A and norovirus
  • Parasites that cause gastrointestinal illness
  • Respiratory irritation from contaminated air and odors

What to Do Right Away

  1. 1. Keep Everyone Out of the Area

    Especially children, pets, and anyone with a weakened immune system.

  2. 2. Stop Using Water and Drains

    Flushing or running water can push more sewage into the home.

  3. 3. Turn Off HVAC in the Area

    This helps prevent contaminated air from spreading to other rooms.

  4. 4. Do Not Attempt DIY Cleanup

    Household cleaners and shop vacs are not enough to safely remove Category 3 contamination.

  5. 5. Call a Sewage Cleanup Professional

    Fast, safe extraction and sanitization protect your family and your home.

How Professionals Handle Sewage Cleanup

Trained technicians wear protective equipment, contain the affected area, extract contaminated water, remove porous materials that cannot be saved, and apply antimicrobial treatments before drying. Moisture readings confirm the structure is dry before rebuild begins.
