. While a common cause of residential water damage is often the failure of a sump pump, many homeowner's insurance policies do not cover the associated costs without an addendum which adds to the monthly premium of the policy. Often the verbiage of this addendum is similar to "Sewer and Drain Coverage."
Those individuals who are affected by wide scale flooding may have the ability to apply for government and FEMA grants through the Individual Assistance program. On a larger level, businesses, cities, and communities can apply to the FEMA Public Assistance

program for funds to assist after a large flood. For example, the city of Fond du Lac Wisconsin received $1.2 million FEMA grant after flooding in June 2008. The program allows the city to purchase the water damaged properties, demolish the structures, and turn the properties into public green space.
Causes
Water damage can originate by different sources such as: broken dishwasher hose, washing machine overflow, dishwasher leakage, broken pipes, clogged toilet, leaking roof, moisture behind walls, foundation cracks, plumbing leaks, and bad weather (snow, rain, floods). As far as insurance coverage is concerned, most damage caused by bad weather is considered flood damage and normally isn't covered under homeowners insurance. Coverage for bad weather would usually required flood insurance.Categories
Water damage is typically classified into one of the following three categories:Category 1 Water - Refers to a source of water that does not pose substantial threat to humans and classified as "Clean Water". Examples are broken water supply
Water supply
Water supply is the provision of water by public utilities, commercial organisations, community endeavours or by individuals, usually via a system of pumps and pipes...
lines, tub or sink overflows or appliance malfunctions that involves water supply lines.
Category 2 Water - Refers to a source of water that contains a significant degree of chemical, biological or physical contaminants and causes discomfort or sickness when exposed or even consumed. Known as "Grey Water". This type carries micro organisms and nutrients of micro organisms. Examples are toilet bowls with urine
Urine

Sewage

Also known as wastewater, it is more than 99% water and is characterized by volume or rate of flow, physical condition, chemical constituents and the bacteriological organisms that it contains...
, seawater, rising water from rivers or streams, ground surface water or standing water. Category 2 Water or Grey Water that is not promptly removed from the structure and or have remained stagnant for 48-72 hours may be re classified as Category 3 Water. Toilet back flows that originates from beyond the toilet trap is considered black water contamination regardless of visible content or color.

is determined by the probable rate of evaporation based on the type of materials affected, or wet, in the room or space that was flooded. Determining the Class of Water is an important first step, and will determine the amount and type of equipment utilized to dry-down the structure:.
Class 1 - Slow Rate of Evaporation
Evaporation
Evaporation is a type of vaporization of a liquid that occurs only on the surface of a liquid. The other type of vaporization is boiling, which, instead, occurs on the entire mass of the liquid....
. Affects only a portion of a room. Materials have a low permeance/porosity. Minimum moisture is absorbed by the materials.
Class 2 - Fast Rate of Evaporation. Water affects the entire room of carpet and cushion. May have wicked up the walls, but not more than 24 inches.
Class 3 - Fastest Rate of Evaporation. Water generally comes from overhead, affecting the entire area; walls, ceilings, insulation, carpet, cushion, etc.
Class 4 - Specialty Drying Situations. Involves materials with a very low permeance/porosity, such as hardwood floors, concrete, crawlspaces, plaster, etc. Drying generally requires very low specific humidity
Humidity
Humidity is a term for the amount of water vapor in the air, and can refer to any one of several measurements of humidity. Formally, humid air is not "moist air" but a mixture of water vapor and other constituents of air, and humidity is defined in terms of the water content of this mixture,...
to accomplish drying.
Restoration
Different removal methods and measures are used depending on the category of water. Due to the destructive nature of water, restoration methods also rely heavily on the amount of water, and on the amount of time the water has remained stagnant. For example, as long as carpet has not been wet for longer than 48 hours, and the water involved was not sewage based, you can usually save the carpet; however, if the water has soaked for longer, then your carpet is probably irreparable and will have to be replaced.

personnel, or by the homeowners themselves; however, contacting a certified professional water damage restoration specialist is often regarded as the safest way to restore water damaged property due to their training and extensive experience. Most are usually listed under "Fire and Water Restoration" and they can help speed repairs, whether for individual homeowners or for the largest of institutions. Fire and Water Restoration companies are reg ulated by the appropriate state's Department of Consumer Affairs - usually the state contractors license board. In California, all Fire and Water Restoration companies must register with the California Contractors State License Board. Presently, the California Contractors State License Board has no specific classification for "water and fire damage restoration." Hence, the Contractor's State License Board requires both an asbestos certification (ASB) as well as a demolition classification (C-21) in order to perform Fire and Water Restoration work.
