Most people hear “Category 3 water” and think it just means really dirty water. That’s not accurate—and that misunderstanding is where properties get destroyed.

Category 3 water is water that’s contaminated enough to cause illness. We’re talking sewage backups, toilet overflows that include waste, floodwater, and water that’s been sitting long enough to grow bacteria. Once clean water mixes with contaminants or sits untreated, it can become Category 3 very fast.

At that point, the issue isn’t just drying—it’s health risk. Materials often need to be removed, not saved. Proper containment, PPE, and documentation matter.
