Am I in the City of Lithonia?
Possibly not. The City of Lithonia is a small historic granite-quarrying town around Main Street, about 18 miles east of downtown Atlanta. The Lithonia mailing area in the 30038 and 30058 ZIPs is much larger and overlaps Stonecrest and unincorporated DeKalb. That matters for permits: inside city limits, the City of Lithonia's Building and Permitting Division issues plumbing permits as their own trade permit type, at City Hall on Main Street (770-482-8136). Addresses outside the city go to Stonecrest or DeKalb County.
Who fixes a water main or sewer problem?
Everywhere in the Lithonia area, DeKalb County Department of Watershed Management handles water and sewer; county crews have repaired mains in Lithonia, including near Kilgore Road. DeKalb's emergency repair line, 770-270-6243, is staffed day and night. DeKalb is responsible for the service line from the main to the meter, including the meter. The line from the meter to the home's plumbing is the owner's, so a leak there needs a plumber.
Is my service line a concern?
DeKalb publishes a service line inventory where customers can check the material of their line, and its 2026 report advises extra flushing for homes with lead or galvanized service lines. If a leak shows up on an older line, it is worth asking the plumber what the pipe is made of. About 16% of homes in the 30058 ZIP were built before 1980.
While you wait, keep the main closed, shut off the water heater if it is the source and switch off power to wet rooms. During a sewer backup, stop using all drains in the house. If the indoor valve will not turn, the water can usually be shut at DeKalb's meter pit outside. Older houses near Main Street may have crawl spaces, so clear a path to the access door before help arrives.
Local note
Lithonia is a gateway to the Arabia Mountain National Heritage Area, and older streets ring the Main Street core, where aging valves and drains are more common. Ask about after-hours pricing when you are connected. Arrival depends on the hour and the plumber's schedule, so no time is promised.
