What Type Of Water Is Flooding In Your Home

While all types of floods are capable of inflicting massive amounts of water damage on your property, some are just inherently more dangerous than others. Floods are classified according to one of three categories, depending on which types of contaminants are present in the water. Read on to see which type of water is flooding your home in O'Fallon, MO.

1. Category 1: Clean Water Floods
Much like the name implies, Category 1 floods are characterized by an absence of contaminants. It is possible for these types of floods to transform into more dangerous varieties if outside contaminants are introduced to the water. Clean water floods are typically caused by:

  • Supply line bursts
  • Leaky pipes
  • Rain water or snow melt

2. Category 2: Gray Water Floods
Category 2 floods do contain mild amounts of contamination, but not enough to be considered a biohazard. If left untreated for 48 hours, a Category 2 flood can quickly become a Category 3. Gray water floods are usually a result of:

  • Sump pump failures
  • Malfunctioning household appliances, such as dishwashers and washing machines
  • Broken aquariums

3. Category 3: Black Water Floods
Category 3 floods are the most dangerous types of floods. They're categorized by the presence of human/animal fecal matter, raw sewage, dangerous chemicals and other types of biohazards. These floods are extremely dangerous and can inflict massive amounts of water damage, so you should never attempt to remediate them on your own. They're often caused by:

  • Toilet back flow
  • Sewage overflow
  • Rising groundwater
  • Overflowing banks from rivers or streams

It's important to take all types of water damage seriously, but you need to be especially wary of damage caused by black water floods. If not treated properly, the situation will only get worse and worse. It's best to contact flood remediation experts if your property has been affected by Category 3 flooding.
