Sewage backups can cause serious damage to your home and pose severe health risks. The contaminated water carries bacteria, viruses, and toxic chemicals that can lead to infections and diseases. It can also weaken your property’s structure and create foul odors that linger for weeks. If not handled quickly, it can spread and cause even more harm. Cleaning a sewage backup must be done carefully to ensure safety. 

Here are five ways sewage and sewer water can be toxic and hazardous to both your property and your health.

Exposure to harmful bacteria and viruses

Sewage water is full of dangerous bacteria like E. coli and Salmonella, as well as viruses that can cause serious infections. Direct contact or inhaling contaminated air can lead to stomach illnesses, skin infections, and respiratory problems. Without proper protective gear and sanitization, exposure can have long-term health effects.

Mold growth and air contamination

Moisture from sewage backups creates the perfect environment for mold growth. Mold spores spread quickly, affecting indoor air quality and leading to breathing problems. People with asthma, allergies, or weak immune systems are especially vulnerable. If not cleaned properly, mold can remain hidden in walls, carpets, and furniture, causing ongoing health issues.

Structural damage to your home

Sewage water weakens floors, walls, and foundations. Wood absorbs contaminated water, leading to rotting and warping. Drywall and insulation become soaked and must be removed to prevent further damage. The longer the sewage sits, the greater the destruction, which can result in costly repairs and unsafe living conditions.

Lingering foul odors and toxic gases

Raw sewage releases toxic gases like methane, ammonia, and hydrogen sulfide. These gases not only create unbearable odors but also pose health risks when inhaled. High levels of these fumes can cause headaches, dizziness, nausea, and in extreme cases, respiratory failure. Proper ventilation and deodorization are necessary to remove these harmful substances.

Pest infestations and disease spread

Standing sewage attracts pests like cockroaches, rats, and flies. These pests carry additional diseases and worsen contamination. Once they enter your home, they can spread bacteria and create an even bigger problem. Proper cleaning, disinfecting, and sealing of affected areas help prevent infestations and further health risks.

Final thoughts

Sewage backups are more than just a mess—they are a serious threat to your health and home. The bacteria, mold, and toxic gases can cause long-term damage if not handled properly. Quick action, professional cleaning, and thorough sanitization are essential for restoring safety. Always take the necessary precautions when cleaning a sewage backup to protect yourself and your property.
