Acworth runs its own electric utility but not water. Cobb County Water System serves the city and is responsible only up to the meter, so a leak in the line under your slab is the owner's to repair. Call the number on this page to be connected with a local plumber in Acworth.

Does Acworth or Cobb County handle my water line?
Neither, once it's past the meter. The City of Acworth runs Acworth Power and sanitation, but its utilities page sends water and sewer issues to Cobb County Water & Sewer. Cobb County Water System owns and maintains the line from the main to the meter. The pipe from the meter to the building is the property owner's responsibility. For broken lines on Cobb's side, use Cobb's emergency line.
Why would a newer Acworth home leak under the slab?
Acworth, "the Lake City" on Lake Acworth and Lake Allatoona, is mostly 1990s and 2000s subdivisions around a historic Main Street. Census survey figures via Point2Homes give a median year built of 2000, with about 14% of homes built before 1980. In younger slab homes, leaks rarely come from pipe wearing out with age. More often it's a joint buried in the slab, a line damaged before the concrete was poured, or pipe chafing as the slab and soil shift. Cobb's water is disinfected with free chlorine rather than chloramine, and nothing in the utility's reporting points to water chemistry as a cause.
Who issues the permit?
The City of Acworth issues residential plumbing permits through its own Development Department and Building Inspections office, not Cobb County. Applications are on the city's permits page, and there's an online Construction Permit Self-Service system. A plumber rerouting or replacing a water line will typically handle the permit.
In a newer home, ask whether the leak is on a branch or the main run. A branch leak can often be bypassed with a short new line through a wall rather than opening tile.
An Acworth note
Lake-area homes often have irrigation. Shut it off before doing a meter test so sprinklers don't hide a slow leak, and check outdoor spigots before suspecting the slab.
If the home is still within a builder warranty period, check the terms before scheduling work. And when the plumber arrives, have the water heater accessible and any warm or damp spots on the floor marked; that shortens the search and helps limit how much flooring has to come up.
