Union City's Water & Sewer Division operates the city's wastewater collection system, about 91 miles of sewer lines, so a sewer line replacement here means new pipe for the private lateral from your home to the city's sewer. The city says Public Works can't work on private property, which leaves that lateral to a plumber. Call the number on this page to be connected with a local plumber in Union City.
Who maintains what in Union City?
The Water & Sewer Division operates the collection system and lift stations, and the city's utility FAQ is clear that Public Works cannot work on private property and that customers should call a plumber for repairs on their side. That FAQ is written about water leaks past the meter, and no city page we found states exactly where the city's sewer responsibility ends, so ask the division before work near the street is priced. Its number is (770) 306-6855, weekdays 8 to 5; no after-hours number is published on the page, so City Hall (770-964-2288) is the fallback.
How old is the sewer line under a Union City home?
Usually not very. Union City grew into a suburban bedroom community for metro Atlanta workers, and the median home was built in 2002, with about 22.8% predating 1980, according to ACS 2019-2023 estimates. In newer homes the lateral is plastic, and when it fails it's usually from a low spot where backfill settled, a joint pushed apart during construction or a crack from later digging. The older homes near the historic Union Street main street are where clay or cast iron may still be in the ground and where full replacement is most common.
What permit is needed?
Plumbing permits are issued by Union City Community Development's Building Permits Division and applied for through the city's online iWorQ portal. The office is at 5041 Union Street. The plumber typically pulls the permit and schedules the inspection while the new pipe is still exposed, so slope and joints can be checked.
A short local note
Because the city's crews stop at your property, any delay in sorting out ownership falls on the homeowner. If the camera shows the worst damage close to the street, call the Water & Sewer Division with the footage in hand before anyone digs. It's a five-minute conversation that can settle who pays for which section. Keep the footage and the permit record together; they'll answer a buyer's questions if you sell, and help the next plumber who works on the line.
