Lithonia homes are on DeKalb County Department of Watershed Management sewer, and DeKalb Watershed handles problems in the public system. A sewer camera inspection films the drain line from your house to show roots, cracks, sags or blockages and where they are. Call the number on this page to be connected with a local plumber in Lithonia.

Who handles sewer in Lithonia?
DeKalb County Watershed Management. It operates the Pole Bridge and Snapfinger treatment plants; which one serves Lithonia was not confirmed. DeKalb Watershed's 24-hour emergency repair line, 770-270-6243, is the number for sewage coming from a manhole or the street. A backup that stays inside your house is usually in your own drain line, which is a plumber's job.
Note that the "Lithonia" mailing area is much larger than the small City of Lithonia and overlaps Stonecrest and unincorporated DeKalb. That matters for permits, not for sewer service.
How old are drain lines around Lithonia?
The city itself is a small historic granite-quarrying town with a Main Street commercial core ringed by older residential streets, and homes there may have older drain pipe with joints that roots can enter. We do not have a housing-age figure for the city alone. Across the much larger 30058 ZIP, only about 16% of houses were built before 1980, so newer plastic lines are more typical in the surrounding subdivisions. Plastic resists roots but can sag or separate.
Which permit office applies to my repair?
Inside city limits, the City of Lithonia Building and Permitting Division at 6920 Main Street issues plumbing permits as their own trade permit type, with applications through the city's Citizen Portal. If your address says Lithonia but you are in Stonecrest or unincorporated DeKalb, a different office applies. The plumber doing the repair normally files the permit; just confirm which jurisdiction you are in.
Before the camera visit, stop heavy water use, uncover the cleanout cap if you can, and note which fixtures have been slow. Ask for a copy of the footage so you can compare quotes and keep a record of the line's condition. Mention any large trees near the line's route as well.
A Lithonia note
Older streets near the Lithonia Historic District have mature trees close to the houses. If you have recurring clogs and big trees, ask the plumber to look closely at each joint along the run for roots. If the footage shows a defect in DeKalb's part of the system, report it to the county with the recording.
