Types and Sources
A lot of homeowners think that water damage control to their property is something that they can easily fix on their own. In fact they assume that the water control is a simple process that will involve pumping out the water and drying out the area. Water losses fall into one of three categories. Determining these categories is the key to introducing the proper drying techniques. Indeed this will also designate what can and can not be restored.
If you did not know about any of the following details, surely let a commercial flood cleanup contractor carry out your basement flood clean.
CATEGORY 1 – Clean Water
Water losses from category 1 originate from a source not posing harm to humans.
Sources of category 1 water may including:
- broken water supply lines
- sink overflows with no contaminants
- appliance malfunctions involving water supply lines
- melting snow
- falling rain water
- broken toilet tanks
- toilet bowls that do not contain contaminants. In other words, additives
However, if left untreated for 72 hours, category 1 water becomes category 2 water.
CATEGORY 2 – Gray Water
This water contains a significant level of contamination. Category 2 also has the potential to cause discomfort or sickness if consumed by or exposed to humans.
Category 2 water carries microorganisms and nutrients for microorganisms. Its sources may include discharge or overflows from any of the following:
- washing machines
- toilet bowls (with some urine but no feces)
- sump pump failures
- seepage due to hydro static pressure
- broken aquariums
Gray water may contain chemicals, bio contaminants, and other forms of contamination. For example, physical hazards and is unsuitable for consumption. When affected with category 2 water, as a result carpet padding needs to be removed and properly disposed of.
If left untreated, category 2 water becomes category 3 water in 48 hours or less.
CATEGORY 3 – Black Water
Black water contains pathogenic agents and is grossly unsanitary.
Category 3 water includes sewage and other contaminated water sources. Entering or affecting the indoor environment. Sources may be toilet back flows that originate from beyond the toilet trap and all forms of flooding. From seawater, ground surface water, and rising water from rivers and streams. These types of water carry silt and organic matter into structures and create black water conditions.
The health of workers and occupants is the most important consideration when dealing with sewage back flows. Always remove and properly dispose of both carpet and padding affected by a Category 3 water losses.
SPECIAL WATER LOSSES SITUATIONS
When a regulated material is present in any water damage situation, specialized expert may be necessary to assist in damage assessment.
Regulated materials may consequently pose potential or recognized health hazards and risks. Besides categories of water damage, there are also 4 classes per the IICRC. Water damage is divided into class based on the rate of evaporation required. Often the type of material that has been affected is the determining factor.
The water loss has been limited to only a partial room area and the materials effected are of low porosity. There is little or no wet carpet or cushion.
The entire room is affected as well as the carpet and cushion. Water has wicked up the walls 1-2 feet. Moisture remains in the structure of the building.
The slowest evaporation rate and water may have come from above. Ceilings, walls, carpet, cushion, and sub floor is all saturated. Surely will require ample time to dry.
Class 4 comprises wet materials with low porosity or permeation. Such as hardwood, concrete, stone, brick, or plaster. Water has formed deep pockets of saturation and will require special equipment that creates an environment of very low humidity.
As you can see, water damage is a very serious matter. If not dealt with immediately, the negative health effects are numerous. If your home or other property has been affected. By any type of water mentioned or not mentioned above, I recommend calling a professional restoration company ASAP. Above all, they will know exactly what to do.
