In the restoration industry there are three categories of water and as industry professionals it is our job to determine which category of water each damage has. The most severe category is Category 3 which is also commonly called CAT 3, Black Water or Dirty Water. Category 3 water (Black Water) is highly contaminated water that is potentially toxic to anyone inside the dwelling.
The water is considered category 3 (Black Water) if it meets any of the following criteria. Sources include sewage backup, flooding from rivers or streams, toilet overflow with feces or stagnant liquid that has begun to support bacterial growth. If Category 1 or Category 2 has been left untreated for more than three days, it is likely that it will develop into Category 3 (Black Water). If your damage is deemed as Category 3 (Black Water), 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 is not always visually black or dirty. In fact, most times it is completely translucent.
