Sewage Damage

Three Categories of Water Damage Most Commonly Covered by Homeowners Insurance

Water damage is serious business, and it can come from many sources, including a flood, broken appliances, burst pipes, and more. But did you know there are three types of water damage? When water damage happens, the next step is cleanup and restoration. Water is categorized by its level of contamination before an action plan can be considered. Because the category of water damage can affect an insurance claim, it is also important insurance companies understand what the cleanup and restoration professionals at SERVPRO® look for during evaluation and water damage restoration.

Here are the three categories of water damage so you can be prepared if it ever happens to your property:


Category 3 Water Damage

Category 3 water damage is defined as “Grossly unsanitary water containing pathogenic agents, arising from sewage or other contaminated water sources and having the likelihood of causing discomfort or sickness if consumed or exposed to humans.” Category 3 water damage is considered grossly contaminated. It may also be called “black water.”

Category 3 water damage is most extreme. It includes:

  • Sewage
  • Other contaminated water sources that may have entered an indoor environment or affected it in some way
  • Category 2 water that is not efficiently removed from an affected structure; it may be reclassified as Category 3
  • Toilet backflows that began beyond the toilet trap, regardless of whether visible content is visible or it has a particular color
  • River or stream water
  • Rainwater mixed with sewage



Category 2 Water Damage

Category 2 water damage is defined as “Water containing a significant degree of chemical, biological and/or physical contamination and having the potential to cause discomfort or sickness if consumed by or exposed to humans.” When listed as Category 2 water damage, the water is considered significantly contaminated since it contains microorganisms and nutrients for microorganisms. It may also be called “grey water.”

Category 2 water damage events can include but are not limited to:

  • Sprinkler water for fire protection
  • Hydrostatic pressure seepage
  • Sump pump collapses
  • Toilet bowl overflow with urine (no feces)
  • Washing machine discharge
  • Dishwasher discharge
  • Condensate and chilled water

Category 1 Water Damage

Category 1 water damage is defined as “Water originating from a source that does not pose substantial harm to humans. Category 1 water is also referred to as ‘clean water.’” In other words, this water is considered sanitary.

Water damage events that may cause Category 1 water damage can include but are not limited to:

  • Rainwater
  • Melting snow
  • Melting ice
  • Broken appliance water lines
