Sewage is classified as Category 3 or “black” water, which is grossly contaminated and can contain pathogenic, toxigenic, or other harmful contents These traits create additional challenges in the cleanup process.

There is a significant difference in the cleanup requirements for black water and clean water damage. For example, most building materials including flooring, lumber, and sheetrock can be dried in place following a clean water loss. However, once contaminated with sewage, these materials will need to be removed and replaced. Solid, non-porous surfaces including concrete can be cleaned and sanitized. Another big difference between blackwater clean-up and clean water damage restoration is the issue of cross-contamination. During the drying process of clean water, the biggest safety concern is preventing mold and inspecting for structural integrity. However, in the case of blackwater cleanup, it is critical to contain the damage and the water to the affected area to prevent the spread of dangerous microbes.

Never trust sewage restoration to just any cleaning crew. Hire the IICRC team that understands the sewage cleanup process and the importance of performing the steps correctly.
