Restoration Terminology: Understanding Categories of Water In Your Home or Business
According to IICRC Standard and Reference Guide for Professional Water Damage Restoration(IICRC S500), there are three categories of water that cause damage in buildings. They are summarized as follows:
Category 1 Water (Clean Water)
Water that originated directly from a sanitary source and when exposed to it, either through the skin, inhaled or ingested, does not cause a great deal of harm to humans. Examples of Category 1 Water: broken water supply lines, melting ice or snow, falling rain water, and tub or sink overflows (no contaminates). Category 1 water may become progressively contaminated as it mixes with soils on or within floor coverings or building assemblies (walls, decking, subflooring). Time and temperature, which promote the growth and amplification of microorganisms in water can cause Category 1 water to degrade
Category 2 Water (Gray Water)
Defined as water with bacteria present, but no solid waste, carrying microorganisms and nutrients for microorganisms. Category 2 water does have the potential to cause discomfort or sickness if consumed or exposed to humans. Examples of Category 2 water: discharge from dishwashers or washing machines, toilet bowl overflows (urine, no feces), seepage due to hydrostatic pressure, and sump pump failures.
Category 3 Water (Black Water)
Contains pathogenic agents and is grossly unsanitary which includes raw sewage and other contaminated water sources, such as flooding from sea water, ground surface water and rising water from rivers or streams. Category 3 water is highly contaminated and could cause death or serious illness if consumed by humans.
