Call your water utility for leaks in the street, at the water main or at the meter, and call a licensed plumber for leaks between the meter and your home. Marietta Power & Water serves the City of Marietta, and Cobb County Water System serves unincorporated Cobb County.
Leak responsibility is the split between what the water utility maintains and what the property owner maintains. The water meter marks the dividing line. Our Marietta leak detection and repair plumbers handle every leak on the home side of the meter.

How Do You Tell Which Side of the Meter Leaks?
Close the home’s main shutoff valve and watch the meter. A meter that keeps moving points to a service line leak. Water at the meter box points to the utility side. Our guide to the water meter leak test walks through each step.
Who Is Responsible for Sewer Leaks and Backups?
The utility maintains the public sewer main, and the homeowner maintains the private sewer lateral from the home to the public connection. Call the utility for sewage overflowing from a manhole or the street. Call a plumber for backups inside the home.
Sewer laterals in older Marietta neighborhoods fail from roots, clay soil and aging pipe. See our Marietta sewer line repair service.

Does the Utility Adjust the Bill After a Leak?

Who Do You Call for a Gas Leak?
