The short answer
The Health Risks from Sewage Contamination
Sewage contains a dangerous mix of pathogens, including E. Coli, norovirus, and parasites. These microorganisms can cause serious illnesses, from gastrointestinal infections to skin rashes. The risk is not just from direct contact; pathogens can become airborne or spread to other surfaces. Touching a contaminated item and then your face can lead to infection, making thorough cleanup essential for safety.
Young children, elderly individuals, and anyone with a compromised immune system face the highest risk. Even after visible sewage is gone, invisible pathogens can linger on surfaces. This is why general cleaning with household products is often insufficient. Professional-grade disinfection protocols are designed to address these hidden biological hazards effectively.
Which Items Must Be Discarded
Porous materials that absorb sewage should almost always be thrown away. This category includes mattresses, pillows, particle board furniture, and drywall. These materials act like sponges, trapping contaminants deep inside where disinfectants cannot reach. Attempting to clean them may only spread germs and create a lingering odor and mold problem.
Food items, cosmetics, and medicines that had any contact with sewage must be discarded immediately. Their packaging is not a reliable barrier. Similarly, children's plush toys and stuffed animals are difficult to sanitize completely and pose a direct risk if chewed on. When in doubt, it is safer to err on the side of disposal to protect your household's health.
- Mattresses, box springs, and upholstered furniture
- Carpeting, padding, and area rugs
- Drywall and insulation materials
- Particle board or pressed wood items
- Cardboard boxes and paper products
- Stuffed animals and porous toys
Items That Can Be Salvaged
Non-porous, hard surfaces like glass, metal, and solid plastics can often be saved. This includes dishes, some hard toys, and metal tools. Salvaging requires a meticulous, multi-step process of washing, disinfecting, and rinsing with appropriate agents. The items must be completely submerged in a disinfectant solution for the recommended contact time to ensure all pathogens are killed.
Even with non-porous items, the decision to keep them depends on the level of contamination and their value. High-touch kitchenware or baby items may warrant replacement for peace of mind. A thorough inspection by water damage pros can help you decide what is salvageable based on the specific circumstances of the contamination event.
The Professional Cleaning Process
Local water damage pros follow strict industry standards for sewage cleanup. The process begins with removing all unsalvageable waste and extracting standing water. They then use commercial-grade antimicrobial agents to disinfect all affected hard surfaces. Specialized equipment like air scrubbers is used to clean the air of particles and odors. This systematic approach targets both visible and hidden contamination.
The pros wear full personal protective equipment, including respirators, gloves, and coveralls, to protect themselves and prevent cross-contamination. They know which disinfectants are EPA-registered for Category 3 water loss, which includes sewage. Their methods are designed to break the chain of infection and make the affected area safe for reoccupation, which is difficult to achieve with DIY efforts.
Insurance and Cost Considerations
The cost for professional sewage cleanup can vary widely, often ranging from several thousand to tens of thousands of dollars. The final price depends on the affected area's size, the extent of contamination, and the materials involved. Many homeowner insurance policies may provide coverage for sudden, accidental sewage backups, but not for neglect or lack of maintenance. Policies vary, and your insurer decides what is covered.
Documenting the damage with photos and videos before any cleanup begins is crucial for an insurance claim. Keep records of all discarded items. You should contact your insurance company promptly to start the claims process. Be prepared to discuss the cause, as this will be a key factor in their coverage determination.
- Size of the affected area and volume of water
- Type of materials damaged (porous vs. non-porous)
- Extent of structural damage to walls or floors
- Need for content cleaning or odor removal
- Time required for drying and dehumidification

Can I clean sewage contamination myself?
DIY cleaning is not recommended due to severe health risks. Household cleaners are ineffective against dangerous sewage pathogens. Without proper protective gear, you risk direct exposure. Professional disinfection uses industrial-grade chemicals and equipment to ensure safety.
How long does sewage cleanup take?
A complete cleanup and drying process often takes three to five days, but complex cases can take longer. The timeline depends on the contamination level and materials affected. The area should not be used until professionals confirm it is safe.
What should I do immediately after a sewage backup?
Turn off the electricity to the affected area if safe to do so. Evacuate children and pets. Avoid contact with the sewage water. Contact local water damage pros who handle sewage emergencies. Do not use sinks or toilets connected to the backed-up line.
