Mableton became a city recently, but its sewer still comes from Cobb County Water System, so a sewer line replacement in Mableton means new pipe for the private lateral between your house and the county's sewer. Many homes along the older rail-era corridor date from the 1960s to the 1980s, and those laterals are often ready to be replaced rather than patched again.

Who does what now that Mableton is a city?
Cityhood changed the permit office but not the sewer utility. Cobb County Water System lists the City of Mableton among the places it serves, and its emergency line, 770-419-6201, handles sewer backups and broken lines on the public side. Cobb's published pipe-ownership rule covers the water line, from main to meter; it doesn't spell out the sewer split, so ask the county where its portion of the connection ends if damage is near the street.
Permits, on the other hand, now come from the City of Mableton Building Division. It issues plumbing permits that specifically cover water, sewer and gas line installations or repairs, and applications go only through the Cloudpermit portal. The office is on Mableton Parkway.
How old are Mableton's laterals?
Mableton is an older community along Veterans Memorial Highway with many 1960s-1980s homes plus newer subdivisions. The median home dates to 1988 and about 34.6% predate 1980, according to ACS 2019-2023 estimates (the source doesn't say whether that covers the new city boundary or the older census area). The older houses near Floyd Road and the Nickajack area are where clay or cast iron is likeliest. Newer homes generally have plastic, which tends to fail from a belly in settled soil or a crack from later digging.
Is replacement better than another repair?
It depends on what the camera shows. A single root intrusion on otherwise sound pipe is often worth fixing in place. Roots at many joints, scale-thinned cast iron or a long sag usually make a full new lateral the better use of money. If the old route still has its slope, bursting or lining can avoid a long trench.
A local note
Because Mableton's permit system is newer than the county's, ask the plumber to confirm the current Cloudpermit steps before the job is scheduled, and keep the permit record with your house papers. A buyer's inspector will often ask about the sewer lateral on an older Mableton home, and a permit plus camera footage of the new line answers the question quickly. If you're replacing only part of the run, note which section is new so the next plumber knows what they're looking at.
