Most insurance claims are related to water damageWater is one of the most common causes of damage that can occur in a commercial or residential building. According to ISO (Insurance Services Office), water damage claims are the second most frequent insurance claim, following wind and hail damage. There are many things to look for when it comes to water damage. One of those things is the category of water damage.

What do you need to know about the different categories of water?

The different categories of water refer to the source of the water damage and other potential contaminants, including what the water may come in contact with. Water cleanliness plays a major role in the risk that the water poses to anyone or anything that comes in contact with it.

The IICRC S500 says the categories of water “refer to the range of contamination in water, considering both its originating source and its quality after it contacts materials present on the job site”. Although they are no longer official designations, many still refer to those categories as Clean, Grey, and Black Water. Those terms can be helpful when trying to remember the cleanliness level of each category.

Categories of Water Damage

The IICRC Standard for Professional Water Damage Restoration (IICRC S500) is a procedural standard that defines the 3 categories of water.

  • Sanitary “Clean Water”
  • Significantly Contaminated “Grey Water”
  • Grossly Contaminated “Black Water”

Knowing the definitions of categories and types of water damage situations can help you understand what you’ll be dealing with if you’re dealing with a similar incident.

Categories of Water

Category 1 – Sanitary (“Clean Water”)

The IICRC S500 defines Category 1 water as water that “originates from a sanitary water source and does not pose a substantial risk from dermal, ingestion, or inhalation exposure.” Examples can include:

  • Water supply lines
  • Melting ice/snow
  • Rainwater
  • Toilet tanks
  • Toilet bowls without contaminants

The keywords here are “sanitary water source” and “does not pose a substantial risk”. That is why this water is considered “clean”. It is also why a restoration contractor like Jenkins Restorations can theoretically salvage and dry any affected building material. Wet drywall, carpet, pad, hardwood flooring, and more can and are oftentimes dried and salvaged on Category 1 water damage incidents.

Category 2 – Significantly Contaminated (“Grey Water”)

The IICRC S500 defines Category 2 water as water that “contains significant contamination and has the potential to cause discomfort or sickness if contacted or consumed by humans.” Examples can include:

  • Dishwasher/washing machine discharge or overflow
  • Toilet bowl overflow with urine
  • Hydrostatic pressure seepage (commonly occurs in basements or slabs)
  • Broken aquariums
  • Punctured water beds

Category 2 water loss contain significantly contaminated water. Make sure your restoration contractor removes wet carpet padding and disinfects affected materials like carpeting. Jenkins Restorations uses an anti-microbial spray and HEPA vacuuming to disinfect affected materials after category 2 water damage incidents.

Category 3 – Grossly Contaminated (“Black Water”)

The IICRC S500 defines Category 3 water as water that is “grossly contaminated and can contain pathogenic, toxigenic, or other harmful agents and can cause significant adverse reactions to humans if contacted or consumed.” Examples can include:

  • Sewage
  • Waste line backflows originating from beyond the trap
  • Seawater
  • Rising water from rivers/streams
  • Wind-driven rain from hurricanes/tropical storms

Category 3 water loss contain grossly contaminated water. Your restoration company contractor should remove all affected cosmetic materials such as insulation, hardwood flooring, drywall, carpet padding, carpet, and cushions. Jenkins Restorations uses an anti-microbial spray and HEPA vacuuming to disinfect affected items after category 3 water damage incidents.

Types of Water Losses by Category

Specialty Drying Situations

Certain materials such as plaster, brick, or concrete, require special drying methods even if the water damage is at a Category 1 or 2. This primarily occurs when there’s a large volume of water to these materials.

Category Deterioration

It’s important to be aware that Category 1 water loss can deteriorate into Category 2 or 3 water. This can happen when category 1 water comes in contact with microorganisms such as mold or the water is left in affected items for over 24 – 48 hours. Often you’ll notice this by odors in the damp material.
