Who's Responsible for the Water Line From Meter to House?
The public main vs. the property owner's line — and why your Marietta address doesn't always tell you which authority applies.
Public Main vs. Private Service Line
Every property connected to municipal water has two sections of pipe between the water source and the house: the public main, the larger pipe under or near the street, owned and maintained by the local water utility; and the service line, the smaller pipe that branches off the main, runs through your meter, and continues to your house.
In Marietta's water service area, the City of Marietta's water utility is responsible for the public main up to the meter. From the meter onward, including the pipe running to your house, is the property owner's responsibility. This is stated directly in the City of Marietta's own Water Service Line Inventory.

What If the Leak Is Right at the Meter?
Not every leak lines up neatly on one side of that boundary. A leak right around the meter box itself can be genuinely hard to place just by looking at it. The practical move is to start with the water utility: they can confirm whether the meter and everything up to it is functioning normally on their end.
Why Your Mailing Address Isn't Enough
Here's the part that catches people off guard: having a “Marietta, GA” mailing address does not automatically mean your property is inside the City of Marietta's actual water-service or permitting jurisdiction. Cobb County includes unincorporated areas that carry Marietta mailing addresses but are governed by Cobb County's own water and permitting rules instead.
If you're not sure which authority actually serves your property, Cobb County publishes a jurisdiction lookup tool for unincorporated areas.
Check Before You Assume
Getting this right matters for both who maintains the public main near your property and which permitting process applies to any work on your own line.
Once You Know It's Your Line: What Happens Next
Confirming responsibility is the first step, not the whole process. Once you've got a meter test or other signs pointing to your side of the line, the line gets located and its condition assessed, a licensed professional pulls the required permit on your behalf, and the repair or replacement follows from what that inspection finds.
See Marietta water line permits for the specifics.

Meter-to-House Responsibility: FAQ
Common questions about who's responsible for which section of the line.
Meter-to-House Responsibility: FAQ
Common questions about who's responsible for which section of the line.
Is the water line from the street to my meter my responsibility?
No — in Marietta's water service area, the public main up to the meter is maintained by the City of Marietta's water utility. Your responsibility starts at the meter.
What if my water line breaks between the meter and my house?
That section is the property owner's responsibility, the same as the plumbing inside your home.
How do I know if City of Marietta or Cobb County has jurisdiction over my property?
A Marietta mailing address alone doesn't confirm it. Some Marietta-addressed properties are actually in unincorporated Cobb County. Cobb County provides a jurisdiction lookup tool for unincorporated areas to help residents confirm this.
What if the leak seems to be right at the meter itself?
That determination usually comes down to where the leak is actually located once someone inspects it. If you're not sure, it's reasonable to start with the water utility.
What should I actually do once I know the leak is on my side?
Confirm what you're seeing with a water meter test, then have the line located before any digging happens. A licensed professional handles the permit and the repair itself.
Does responsibility for the line change if I need trenchless replacement instead of a repair?
No. Responsibility for the meter-to-house line stays with the property owner regardless of which method — spot repair, full replacement, or trenchless — ends up being the right fit once the line is inspected.
