What is Sewage Water Anyway?
Sewage water is very different from your average spill. Classified as "black water" or "category 3" in the restoration industry, sewage water is a different beast compared to the water from a leaky pipe. This contaminated water is a toxic cocktail of bacteria, viruses, parasites, and other harmful substances.
Due to its degree of contamination, it poses serious health risks upon exposure. Exposure can affect a person's health from direct contact to inhalation of airborne particles or ingesting contaminated food or water. When dealing with a sewage flood, it is best to leave it to the professionals. They have the gear and know-how to handle it safely and ensure your home is truly clean and safe again.
Sewage Floods: Symptoms After Exposure
Before modern plumbing, waste flowed in the streets, causing widespread illness from poor sanitation. Although we've moved past those days, exposure to raw sewage can still occur from toilets, septic tanks, sinks, tubs, or floor drain overflow.
The health risks associated with sewage damage range from mild to severe, depending on the type and amount of exposure. Common symptoms to watch for after contact with wastewater include:
Gastrointestinal Issues
- Nausea
- Vomiting
- Diarrhea
- Abdominal cramps
Respiratory Problems
- Coughing
- Wheezing
- Shortness of breath
- Asthma attacks
Skin Infections
- Rashes
- Sores
- Itching
- Burning
Eye and Ear Infections
- Conjunctivitis (pink eye)
- Earaches (otalgia)
- Swimmer's ear (otitis externa)
If you or a family member presents any of these symptoms after exposure to sewage water, we strongly suggest you consider medical attention to discard any potentially severe disease. This is especially important for vulnerable populations, which we will discuss in more detail further down this article.

If you or someone in your household falls into one of these categories, it's crucial to take extra precautions to avoid exposure to sewage.
Top Priority: Protecting Yourself and Your Family
Safety should be your number one priority when dealing with sewage damage. Here are some essential tips to protect yourself and your family:
- Leave the Area: If there's a lot of sewage, it's best to leave. Call a professional cleaning company. They know how to handle it safely.
- Protect Yourself: If you must move through sewage water, wear gloves, boots, and a mask. This will prevent direct contact with the contaminated water and airborne particles. Also, the contaminated clothes should be discarded or left for professional cleanup.
- Wash Up: Always wash your hands with soap and water after being near sewage. The Centers for Disease Control and Prevention (CDC) recommends washing your hands for at least 20 seconds and following their 5 steps (wet, lather, scrub, rinse, and dry). If you have any cuts or open wounds, clean them immediately and see a doctor if needed.
- Don't Touch Stuff: Avoid touching anything in contact with the wastewater. We are talking about things like furniture, carpets, and clothes. They will either need to be cleaned by professionals or thrown away.
- Clean Everything: After the sewage is gone, disinfect the affected area. This will kill any leftover germs.
