Have you heard the term black water? In the restoration business, there are three kinds of water, and as industry professionals, it is our job to know what kind of water we are dealing with at all times. The most severe type of water is Category 3 also known as CAT 3, black water or dirty water. Category 3 is the most serious type of water because it is highly contaminated and is potentially toxic to those who come into contact with it. 

Water is considered Category 3 if it meets any of the following criteria. The source of the water is sewage backup, flooding from rivers or streams, toilet overflow with feces or stagnant liquid that has begun bacterial growth. If Category 1 or 2 has been left untreated for more than three days it is more than likely that it will develop into Category 3. If your water damage is deemed as Category 3, it is likely that many pieces of your property will need to be replaced. Anything porous, such as furniture, carpeting and drywall is grossly contaminated. Category 3 water, although referred to as black water or dirty water it is not always visually black or dirty. In fact, most times it is visually translucent.
