Acworth runs its own electric and sanitation but not water: the Cobb County Water System serves the city, and its backflow program requires annual testing by a tester registered with Cobb County, with reports filed through SwiftComply. Call the number on this page to be connected with a local plumber in Acworth.

Whose backflow rules apply in Acworth?
Cobb County's. Acworth Power supplies electricity, but the city's utilities page sends water and sewer issues to Cobb County Water & Sewer, and Cobb lists Acworth among the cities it serves. Cobb's Backflow Prevention Program requires a backflow prevention device on any property with a potential cross-connection that could contaminate the public water system. Every non-residential customer must install a testable assembly on each service connection. For homes, irrigation is the usual reason a device is needed.
Who tests it, and how is it filed?
Assemblies must be tested once a year by a tester registered with Cobb County. The county publishes an approved list of testing companies, and reports are submitted through the SwiftComply portal. If you have questions about your account, Cobb's Backflow Supervisor is at 770-528-3343. Cobb owns the line from the main to the meter; the pipe from the meter to the house, and the assembly on it, are the property owner's.
What should a lake-area homeowner watch for?
Acworth calls itself the Lake City, with Lake Acworth and Lake Allatoona at its doorstep and mostly 1990s and 2000s subdivisions around them. Many of those homes have irrigation, and some have outdoor kitchens or pool fills added later. Each added connection is worth a look, because Cobb's rule is about any potential cross-connection, not just sprinklers. A failed test usually means worn checks or seals that a plumber can rebuild before a retest. A freeze-cracked body means replacement. Residential plumbing permit applications are on Acworth's permits page, and the city's Construction Permit Self-Service portal handles online filing.
An Acworth note
Businesses along Main Street and the GA-92 corridor count as non-residential customers under Cobb's rules, so each water connection needs a testable assembly and an annual report. If you're opening a shop or restaurant in an older building, confirm the existing device suits the new use before the inspection. Homeowners near the lakes should drain the irrigation side in late fall and wrap any assembly that sits above ground, because a cracked body cannot be rebuilt and has to be replaced before the next annual test. When you call, have the device's tag details and any letter from Cobb ready.
