If a pipe has burst or sewage is backing up in your Decatur home, close the main water valve right away, and for a gas smell, leave and call 911 and Atlanta Gas Light at 877.427.4321 from outside. Then call the number on this page to be connected with a local plumber in Decatur.

Why do older Decatur houses fail the way they do?
Decatur is the historic DeKalb County seat, and its housing is old. The median home was built in 1975, about 54% predate 1980 and roughly 23% were built in 1939 or earlier. In close-in neighborhoods like Oakhurst, that means galvanized supply lines that rust from the inside, cast iron and clay drains that crack or collect roots, and gate valves that may not close after decades without use. A small leak in an older house can turn serious quickly when the shutoff will not cooperate.
Who fixes the street side?
The city does not run its own water. DeKalb County Department of Watershed Management supplies Decatur, and its 24-hour emergency repair line is 770-270-6243. DeKalb owns the service line from the main to the meter, including the meter; from the meter to the home's plumbing, the line is the owner's. DeKalb has also replaced sanitary sewer lines in the city. Ownership of every local collection line is not stated, so for a sewer problem at the street, contact the City of Decatur or DeKalb Watershed. DeKalb's public service line inventory lets owners check whether their line is lead or galvanized.
Do I need a permit, and from whom?
Inside city limits, Decatur requires a separate plumbing, sewer, gas or drainage permit regardless of the job's value, and all applications go through the Community Core online portal. The many Decatur-mailing addresses in the 30032 to 30035 ZIPs that sit outside city limits are permitted by DeKalb County instead. A plumber can make the emergency fix first and handle the right permit afterward.
Before the plumber gets there, keep the main closed. If the indoor valve will not turn, the water can usually be shut at the meter pit outside with a meter key. Turn off the water heater if it is involved, shut off power to wet rooms and stop using the drains during a sewer backup. Older Decatur houses often have plaster walls and crawl spaces, so clearing a path to the crawl space door saves time when help arrives.
Local note
Ask about after-hours pricing when you are connected. Arrival depends on the hour and the plumber's schedule, so no time is promised.
