Your Best Defense
Against Blackwater
ASDT has the training and certifications to handle any category of water damage, from clean to extremely unsanitary. When you experience sewage backup or other waterborne hazards, call us.

Sewage Cleanup and Waste Removal Service in Nashville, TN.

Rising stormwater and burst sewer pipes don't flood your property with spotless water. This water is considered hazardous "blackwater." If you experience a burst sewage pipe, hurricane or tornado damage, industrial flooding, contaminants, chemicals, heavy metals, and other hazardous wastes can double the threat of water damage. These substances can pose a serious health risk to you, your family, or your employees, which means you need a restoration company that makes your health and safety a priority.

At ASDT, our water damage cleanup experts rapidly remove contaminated water and use industry-leading technologies to thoroughly clean and disinfect your property. We understand that a sewage spill can be one of the most unpleasant and concerning situations a home or business owner may face. That's why we work quickly, safely, and thoroughly to remove all traces of the damage altogether with all possible precautions in place.

Three Categories of Water Damage

ASDT is fully equipped to handle all three types of water damage defined by the IICRC.

Sewage Cleanup and Waste Removal

Category 1 water, or clearwater, poses the slightest threat of harm to people. Category 1 water damage sources include water supply lines, rainwater, meltwater, and toilet tank water (as long as there are no contaminants). Building materials like wet drywall, hardwood flooring, and carpets can be dried and salvaged with no substantial health risks.

Category 2 water, or greywater, threatens people's health and safety. Greywater is any wastewater used for bathing or showering, washing, or laundering, including water from washing machines, dishwashers, showers, and sinks. This kind of water contains germs, chemicals, fats, oils, and bleaches that can rapidly become septic if left untreated.

Category 3, or blackwater, is the most serious category of water damage. It must be eliminated, and all materials that come into contact must be removed and disinfected thoroughly. Any grossly contaminated water from toilets, urinals, sewer systems, or septic tanks is considered blackwater.

Sewage & Waste Cleanup FAQs

What Do I Do if My Sewer is Backing Up?

If you're experiencing a severe backup and waste flooding into your home, call ASDT's emergency line at 615-207-3877. Avoid contact with the wastewater and evacuate any children or pets. Call your utility company to shut off water and power to the affected area. A plumber will be required if a backed-up septic tank or clogged sewer line causes the backup.

ASDT can handle the issue's comprehensive removal, disinfection, drying, and clean-up phases and assist with the insurance claims process. The faster you call us to clean up the sewage, the safer your property will be and the less extensive the damage will be.

Is Flood Water Toxic?

Yes—stormwater, including flooding due to hurricanes, tornadoes, and intense thunderstorms, is considered category 3 water. This is because as the water flows over soils, pavement, and drainage systems, it comes into contact with sewage, heavy metals, and other chemicals and pathogens. Do not attempt to clean flood water yourself. Instead, call the experts at ASDT.

Can I Clean Up the Sewage Backup Myself?

Professional sewage backup cleanup is always recommended for your total health and safety, as well as that of your family or employees. Professional help is essential if the spill affects more than one location on your property, occurs more than 24 hours ago, is caused by sewer or septic tank backup, or your HVAC system has come into contact with the water (as this poses a cross-contamination risk). Could you call ASDT to get started as soon as possible?
