Plumbers in Marietta, GA

The Cobb County seat

Marietta was recognized as a village in 1834, incorporated in 1852 and remains the seat of Cobb County. Life still centers on Marietta Square, with Interstate 75, Cobb Parkway (US 41) and State Route 120 running through town, the Big Chicken at US 41 and Roswell Road, and Dobbins Air Reserve Base nearby. The city had about 60,972 residents in 2020 and sits about 17 miles from downtown Atlanta.

A city utility for water and sewer

Marietta runs its own utility rather than relying on the county. Marietta Water, part of Marietta Power & Water, provides both water and sewer service. It does not treat water itself: it buys treated water from the Cobb County-Marietta Water Authority, which draws from the Chattahoochee River at the James E. Quarles plant and from Lake Allatoona at the Hugh A. Wyckoff plant. Marietta Water's report shows chlorine disinfection and added fluoride and does not list hardness. Service and maintenance dispatch answers at (770) 794-5230 at any hour.

A Marietta mailing address does not guarantee city service. Homes outside city limits may be on the Cobb County Water System, which serves unincorporated Cobb, so check the name on your bill. Marietta Water's report also says the utility handles lead service line removal, while homeowners are responsible for any lead materials in their own plumbing.

Older housing than the outer suburbs

The median home in Marietta was built in 1987, and about a third, roughly 33%, predate 1980. On the older streets around the Square, a plumber may run into original drain piping, galvanized remnants and sewer lines that have shifted with age; in the many 1980s and later subdivisions, water heaters, valves and fixtures are the usual calls.

Backflow testing and permits

Marietta Water runs its own cross-connection control program. It rates each service as high, medium or low hazard, specifies the device, and wants it installed as close as possible after the meter. Testable devices must be tested every year by a certified tester, with results reported to the utility; Environmental Compliance is at 770-794-5229. Permits for changes to existing buildings, plumbing among them, come from City of Marietta Building Inspections. Addresses outside city limits go to Cobb County instead.

Gas, and how it compares with Atlanta

Marietta Power & Water sells electricity and water, not gas. Residents choose a certificated gas marketer, and the pipes belong to Atlanta Gas Light. If you smell gas, leave the house, then call 911 and Atlanta Gas Light at 877.427.4321 from outside. Compared with Atlanta, Marietta has its own water and sewer utility, its own backflow program and a second water source in Lake Allatoona.
