Black Water

Black water contains pathogens of the nutrients of urine and feces that are diluted in the flush water. It requires treatment either by chemical or biological agents including disinfection. Black water is not suitable for indoors usage before or after any treatment except it is done by systems producing drinking quality water.

Black water may also come from natural floods where heavy rain causes rivers and streams to overflow. When river water mixes with sewer water, it creates blackwater. This water can cause illnesses. The water during floods may also come under black water category, you need to analyze it. Otherwise, it may be harmful for you.

During any natural calamity, if certified water damage restoration experts do not remove black water timely, it will rot, dry out and may further lead to infections and illness due to the airborne contamination.

The Difference!

Black water has come into contact with fecal matter, which contains harmful bacteria and disease-causing pathogens. Moreover, the waste in black water doesn’t break down and decompose fast or effectively hence holds the risk of contamination.

Also, grey water can be reused if preventive measures are taken and it is not recommended to reuse black water until and unless it is not treated well with high purifying systems.
