The Many Classes of Water
Did you know there are three categories and four classes of water? Understanding each type, it’s sources and the risks associated with water damage is very important. When dealing with water inside your home or property, time is always of the essence.
The Categories of Water
Category 1: Clean Water
This category is made of liquid from a clean and sanitary source. While this water may start as clean water it can turn into category 2 rather quickly if not dealt with immediately.
Category 1 sources include water from:
- Water fountains
- Toilet tanks
Category 2: Greywater
Greywater is the gently used water that goes down the drain of your bathroom sink, shower, bathtub, washing machines, and/or utility sinks. As a rule, grey water has not come into contact with human waste, but rather may contain dirt, food, hair, soap, grease and oil, and miscellaneous cleaning products. Grey water may contain levels of contaminants that can cause illness when ingested.
Category 2 sources include water from:
- Washing machine overflows
- Flush from kitchen and bathroom sink drains
Category 3: Blackwater
Blackwater is the worst category of water and could cause illness or even death if not dealt with properly. Blackwater usually refers to water that comes from toilets and can contain human waste and toilet paper.
Category 3 sources include water from:
- Sewer backup
- Toilet overflows that contain feces and toilet paper
- Standing liquid that contains bacterial growth
- Flooding from rivers or streams
The Classes of Water
Only part of a room is affected in a class 1 water loss. This class is the easiest to deal with and has a slow evaporation rate. Affected materials will contain little to no carpet and only consist of low permeance materials like concrete or plywood.
With a fast evaporation rate, class 2 will affect an entire room that contains carpeting where moisture has traveled up the walls at least a foot. Moisture remains in structural materials.
The fastest evaporation rate of the four classes, class 3 usually has a source that has started from above. The entire room will be saturated including ceilings, walls, insulation, sub-floors and carpet.
Specialty drying situations when there has been enough time and water to saturate materials like brick, stone, or hardwood make up class 4.
