When it comes to cleanup and disinfection of commercial spaces, it’s best to call certified water damage restoration experts. The SERVPRO of Richland County team is trained to handle contaminated water emergencies properly and works 24/7 to help our customers get their property back to business.

It’s essential for business owners and property managers to know the different types of contaminated water. You can easily smell or see contaminates in some cases, but water can smell and look perfectly fine, but still be harmful.

Clean, gray and black water: What’s the difference?

Water damage can be classified by three types of contaminated water: clean, gray and black. 

Clean water is free from viruses, bacterias and comes from a source like a broken water supply line or leaking faucet. If not treated quickly, clean water can turn into gray or black water, depending on the length of time, temperature and contact with surrounding contaminants. 

Gray water, or wastewater, hasn’t come into contact with solid human waste but is still considered contaminated. It also may contain bacteria and viruses that cause discomfort or illness. Gray water drains and flows from places such as showers, sinks and baths. It also comes from overflowing washing machines, dishwashers and toilets with urine but no feces.

If done correctly, gray water can be filtered and reused for gardens and lawns; however, it also can quickly degrade if left untreated. 

Black water is highly contaminated and contains harsh chemicals and human waste filled with harmful bacteria and disease-causing pathogens. You should avoid contact with black water as it can cause severe illness or death if ingested. Water is considered black when it comes from a toilet bowl with feces or sewer back-up. It’s also generated from overflowing streams or rivers mixed with sewer water and standing water with microbial growth.

Sewage cleanup and commercial water restoration

Any water contaminated with sewage backup should be considered an emergency and addressed as quickly as possible. The water may contain viruses, bacteria and other microbes that cause serious illnesses. And if black water isn’t removed promptly, it can rot, dry out and lead to airborne contamination. 

SERVPRO professionals are specially trained and have the equipment and protective gear to safely restore your business. Our water damage restoration specialists will inspect your business to determine the appropriate plan of action for the type of water encountered.
