Not all water damage is the same.
When a mitigation company responds to a water loss, one of the first things they determine is the category of water involved. The category affects safety procedures, cleaning methods, and what materials may be salvageable.
If you’re dealing with water damage in Northwest, Montana, here’s what you should know.
Category 1 – Clean Water
Category 1 water originates from a sanitary source and poses little immediate health risk.
Common examples include:
- Burst water supply lines
- Faucet leaks
- Water heater supply line failures
- Appliance supply hoses
When addressed quickly, many building materials and contents can often be dried and restored.
Category 2 – Gray Water
Category 2 water contains contaminants that may cause discomfort or illness if people are exposed.
Common sources include:
- Washing machine discharge
- Dishwasher overflows
- Toilet overflows without solid waste
- Sump pump failures
These losses require additional cleaning and sanitation procedures.
Category 3 – Black Water
Category 3 water is considered grossly contaminated and can contain harmful bacteria, viruses, and other pathogens.
Examples include:
- Sewage backups
- Flood water from rivers or streams
- Toilet overflows containing sewage
Because of the health risks involved, Category 3 losses require specialized personal protective equipment (PPE), containment, and cleaning procedures.
Categories Can Change Over Time
One of the most important things homeowners should understand is that water categories are not permanent.
Clean water left standing for an extended period can become contaminated as it contacts building materials and microorganisms.
This is one of the many reasons why fast mitigation is so important.
