Lithia Springs is unincorporated, so Douglas County issues plumbing permits there, while the Douglasville-Douglas County Water and Sewer Authority supplies water and sewer and requires yearly backflow tests by a certified tester from its list. Gas comes through the Austell Gas System. Call the number on this page to be connected with a local plumber in Lithia Springs.

Local conditions in Lithia Springs
Lithia Springs was a city until residents voted to dissolve its charter in 2000, and today it's an unincorporated community in northeastern Douglas County. It was once a health resort known for its lithia spring water; now it mixes homes, apartments and several data centers along Thornton Road and I-20. The median home dates to 1987, with about a third built before 1980.
The Douglasville-Douglas County Water and Sewer Authority (WSA) is the county's sole water provider and supplies sewer where it's available. Its water comes from the Dog River Reservoir, and its service line inventory found no lead service lines. WSA owns the meter and the lines in the road right-of-way; the customer owns the water and sewer lines from the meter to the building. Business-hours calls go to 770-949-7617, after-hours emergencies to 770-942-6633.
WSA requires customers to install and maintain backflow protection at their own expense and to have devices tested every year by a certified tester from WSA's list, with results sent to WSA. Service can be suspended if reports aren't provided.
Because there's no city government, permits come from Douglas County Building Permits and Inspections on Timber Ridge Drive in Douglasville, 770-920-7201, with inspection requests at 770-920-7333. The county requires plumbing permits for new or renovation work, lawn irrigation included.
Common jobs compared

Signs to act on
- Wet ground between the meter and the building
- A backflow test notice from WSA
- Restroom fixtures that run or clog
- A gas odor near equipment
Timing notes
Book the WSA test early enough to repair a failed device before the report is due. Protect irrigation backflow devices before a freeze. If anyone smells gas, leave first and call 911 or the Austell Gas System at 770-948-1841, option 1.
