A sewage backup is one of those emergencies nobody plans for. One minute your basement drain is gurgling; the next, contaminated water is spreading across the floor. In our years serving Metro Atlanta, we’ve seen well-meaning homeowners make a bad situation worse in the first hour — usually by touching things they shouldn’t. Here’s exactly what to do (and what to avoid) when sewage backs up in your home.
Sewage is what the restoration industry calls Category 3 water — “black water.” It carries bacteria like E. coli and salmonella, viruses, and parasites. That’s why the rules for a sewage backup are different from a clean-water leak from a supply line. With sewage, exposure itself is the hazard, not just the moisture.
Atlanta’s established neighborhoods — Sandy Springs, Dunwoody, Roswell, Brookhaven — have mature trees and, in many cases, decades-old clay sewer laterals. Roots find joints in those pipes and slowly choke the line. Add one of our signature summer downpours overwhelming municipal systems, and backups spike. If your home has a basement, a failed ejector pump or backwater valve is another common culprit — something we covered in our guide to basement and crawl space flooding.
A certified crew will contain the area, extract the sewage safely, remove contaminated porous materials (carpet, pad, affected drywall), disinfect with hospital-grade antimicrobials, and dry the structure to verified moisture standards. Done right, this prevents the two long-tail problems that follow bad cleanups: lingering odor and mold growth inside walls.
Once the cleanup is done, ask about prevention: a backwater valve on the main line, root treatment or pipe repair for older laterals, and a battery backup for your sump or ejector pump. And check your insurance policy today — the water/sewer backup endorsement usually costs little but makes all the difference when you need it.
