Acworth businesses buy water and sewer service from Cobb County Water System, which requires a testable backflow assembly on every non-residential water connection, while the City of Acworth issues the plumbing permit. Most commercial calls here are drains, restrooms, water heaters and those yearly backflow tests. Call the number on this page to be connected with a local plumber in Acworth.

Does every Acworth business need a backflow assembly?
For practical purposes, yes. Acworth runs its own electric utility, Acworth Power, but not water or sewer, so a shop on Main Street or an office near Center Street is a Cobb County Water System customer. Cobb's backflow program says all non-residential customers must install a testable backflow assembly on every water service connection. Each assembly has to be tested once a year by a tester registered with Cobb County, and the report is filed through the Swift Comply portal. The county publishes an approved list of testing companies, and questions go to its Backflow Supervisor at 770-528-3343.
If a test fails, the assembly needs repair or replacement before it can pass. Booking the test well ahead of your due date leaves room for parts.
Which part of the water line is the business's problem?
Cobb County Water System owns the pipe from the main up to the meter. Everything from the meter to the building belongs to the property owner. A leak in the parking lot between the meter box and the wall, or a cracked line under a sidewalk, is a job for a private plumber, not the county. If water is gushing at the meter or in the street, call Cobb's emergency line, 770-419-6201, instead.
The building sewer works the same way in practice: the private line from your cleanout to the county main is yours to keep clear.
Who issues the plumbing permit in Acworth?
The City of Acworth's Development Department, through Building Inspections at City Hall on Center Street. Staff review and issue the construction permits the city's codes require, and the city posts both residential and commercial plumbing permit applications. Applications can also go through its online Construction Permit Self-Service site. A plumber replacing a water heater, adding fixtures in a buildout or rerouting supply lines should expect a permit and inspection; clearing a clog generally doesn't need one.
A note on Acworth's building stock
Acworth is mostly young. Census survey figures put the median home at 2000, with about 13.5% built before 1980. Most commercial work here involves plastic drain lines, newer tank or tankless heaters and restroom fixtures rather than failing cast iron. The older exception is the historic core along Main Street and Old 41, where storefronts have been remodeled many times and a plumber may find a mix of materials behind the walls. Lake-area restaurants and marinas that see busy summer weekends are wise to have grease lines cleaned and the water heater checked before the season starts.
