Acworth refers water and sewer to Cobb County Water System, so a sewer line replacement in Acworth means new pipe for the private lateral running from your home to the county's sewer. The city itself issues the plumbing permit, and since most homes here date from the 1990s and 2000s, failures more often come from settled or damaged pipe than from age. Call the number on this page to be connected with a local plumber in Acworth.

Who runs Acworth's sewer?
Not the city. Acworth runs its own electric utility, Acworth Power, and sanitation, but it sends water and sewer issues to Cobb County Water & Sewer: 770-419-6200 for customer service and 770-419-6201 for emergencies. Call the emergency number if wastewater is coming up in the street or neighbors are affected. Cobb's published ownership rule covers the water service line; for the sewer, ask the county where its portion ends before work near the street is priced.
Why would an Acworth home need a new sewer line?
"The Lake City" is mostly 1990s and 2000s subdivisions around Lake Acworth and Lake Allatoona, with older homes near the historic Main Street. The median home was built in 2000, and about 13.5% predate 1980, according to ACS 2019-2023 estimates. In the newer homes, the culprits are usually backfill that settled and left a low spot, a joint pushed apart during construction, or a crack from later digging for a pool, fence or irrigation. The older houses near downtown are where clay or cast iron may still be in service.
Who issues the permit?
The City of Acworth, not Cobb County. The Development Department's Building Inspections staff review, approve and issue the city's construction permits, and residential plumbing permit applications are on the city's permits page. There's also an online Construction Permit Self-Service portal. City Hall is on Center Street. The plumber usually files and schedules the inspection before backfill, and the inspector checks the new pipe's slope and joints while they're still exposed.
A local note
Lakeside lots can slope toward the water, away from the street. If your house sits below the sewer connection, the lateral's grade and any ejector pump matter as much as the pipe itself, so ask the plumber to check both during the camera inspection. A backwater valve may also be worth discussing if your lowest fixtures sit below the street. On the older lots near Main Street, the pipe may also run under porches or brick walks that predate the house's later additions. The camera will show where it goes, and that route often decides whether lining, bursting or a trench makes the most sense.
