Acworth runs its own electric utility but not water; Cobb County Water System supplies it with free-chlorinated water, and no hardness figure was readable in its reports. Test before you buy a softener. Call the number on this page to be connected with a local plumber in Acworth.

Does Acworth water call for a softener?
Maybe, maybe not, and the reports won't settle it. The City of Acworth refers water and sewer to Cobb County Water System, which buys treated water from the Cobb County-Marietta Water Authority, drawn from the Chattahoochee River and Lake Allatoona. An earlier Cobb report notes free chlorine and added fluoride; the newer report couldn't be read. With no hardness number to rely on, a tap test is the way to decide. Most Acworth homes are 1990s and 2000s subdivisions, with a median build year of 2000, so a softener choice is mostly about protecting fixtures and water heaters rather than older pipes.
Is a carbon filter enough for taste?
Usually, yes. Because Cobb disinfects with free chlorine rather than chloramine, standard activated carbon reduces taste and odor well. An under-sink unit covers drinking and cooking water; a whole-house unit covers showers and every tap. Neither softens water. If you want both, the filter typically goes ahead of the softener on the main line.
Who handles the permit in Acworth?
The City of Acworth issues residential plumbing permits through its own Building Inspections office, not Cobb County, and offers an online Construction Permit Self-Service system. Cutting equipment into the main is plumbing work, so ask the plumber whether your install needs a permit. For water or sewer problems on the street side, the city points residents to Cobb County Water & Sewer at 770-419-6200, with emergencies at 770-419-6201.
One local note
About 13.5% of Acworth homes were built before 1980, mostly near the historic Main Street. If you're in one of those and notice rust, have the plumber check the supply piping before buying a filter for it.
For the newer subdivisions that make up most of Acworth, the most common visit is simpler: a hardness reading, a carbon filter for taste, and a look at whether an original water heater from around 2000 is nearing the end. Combining those into one trip keeps the work, and any permit, in one place. If a softener does go in, ask for a bypass valve and a drain connection that meets code so it can be serviced and regenerate without trouble.
