When a sewage line ruptures or overflows, it can be a major health hazard. Feces and other contaminants can enter your home, contaminating surfaces and potentially causing illness. That's why it's important to have a professional sewage cleanup service on hand to clean up the mess and disinfect the area. ### Cleanup and Disinfection The first step in sewage cleanup is to remove all visible contaminants. This includes feces, urine, vomit, and other bodily fluids. Once the visible contaminants have been removed, the area must be disinfected to kill any remaining bacteria or viruses. The most common way to disinfect a sewage spill is to use a bleach solution. ### How Long Does Sewage Contamination Last? The length of time that sewage contamination lasts depends on a number of factors, including the temperature, the humidity, and the type of surface that has been contaminated. In general, sewage contamination can last for several days or even weeks. It is important to have the area cleaned and disinfected as soon as possible to prevent the spread of disease.
