Categories of Water Damage
9/7/2022 (Permalink)
A categorization of the level of contamination of water in a damaged structure is required to perform loss assessments and evaluation activities. The category of water contamination must be considered so that the correct procedure can be established for processing a water damaged structure and its materials. Water damage is divided into three categories.
Category 1: Water that originates from a sanitary source. Examples include: broken water supply lines, tub or sink overflow, melting snow and ice, falling rainwater, broken toilet tanks and bowls that do NOT contain contaminants.
Category 2: Water contains a significant level of contamination. Examples include: discharge from dishwashers or washing machines, overflows from toilet bowls with some urine but no feces, broken aquariums and punctured water beds. Also, any water that has traveled through building materials.
Category 3: Water that is grossly contaminated and can contain pathogenic or toxigenic agents. Examples include sewage, toilet back-flows that originate from beyond the trap, all forms of flooding and other contaminated water entering or affecting the indoor environment.
