Homes inside Marietta city limits are on Marietta Water, while some Marietta-addressed homes outside the city are on Cobb County Water System. Marietta hasn't published exactly where its responsibility ends, so report anything at the meter to the utility and call a plumber for the pipe across the yard. Call the number on this page to be connected with a local plumber in Marietta.
Marietta water and the homes it serves
Marietta Water, part of Marietta Power & Water, doesn't treat its own water. It buys treated water from the Cobb County-Marietta Water Authority, which draws on the Chattahoochee River and Lake Allatoona, and distributes it across the city. A Marietta mailing address doesn't guarantee city service, though. Many homes outside the limits are Cobb County Water System customers, so the name on your bill decides who to call about the meter. Marietta Water's service and maintenance dispatch is reached at 770-794-5230.
We couldn't find a city page spelling out where the utility's pipe stops. Its water quality report does say Marietta Water handles lead service line removal while homeowners are responsible for lead materials in their own plumbing, which suggests the house-side piping is generally the owner's. Treat the meter box as the utility's call and the run across the lawn as a likely plumber job.
Housing ranges from the historic streets around Marietta Square to later suburbs off Cobb Parkway and Roswell Road. The median home dates to 1987, and about a third were built before 1980, so older lines near downtown may be galvanized or carry patches from past owners.
Repair options compared
| Approach | Best fit | Trade-off |
|---|---|---|
| Section repair | A single failure on otherwise healthy pipe | Fast, but aging pipe nearby may go next |
| Open-trench replacement | Short runs or open lawns | Direct and simple, disturbs the yard |
| Bored or pulled new line | Driveways, walks or old trees over the route | Less surface damage; soil and access must allow it |
Symptoms to take seriously
- A damp patch that returns between the curb and the foundation
- Gradually weaker pressure everywhere in the house
- A meter that keeps turning overnight
- Rusty water from the cold tap in an older home
Seasonal notes
Hard freezes crack shallow or exposed sections, and the leak often shows up only after the thaw. Long dry spells shrink clay soils and can shift brittle joints. A slow leak can be scheduled; a break that floods the yard needs the main valve closed right away. Plumbing permits for the work come from City of Marietta Building Inspections inside the city.
