Duluth is served by Gwinnett County's Department of Water Resources, which maintains the meter and the short pipe from the main to it. Everything on the customer's side of the meter, including the private water service line, is the property owner's to fix. Call the number on this page to be connected with a local plumber in Duluth.

Signs the private line is leaking
- A stripe of lawn that stays wet from the meter toward the house
- Pressure dropping in every room at once
- The leak indicator on the Gwinnett meter turning with all taps closed
- A water bill that climbs while household habits stay the same
- Dampness at the slab edge or crawl space wall where the pipe enters
Water service conditions in Duluth
The city lists Gwinnett County Water Resources for water and sewer, with a water emergency line at 678-376-7000. Water comes from Lake Lanier, treated at the Shoal Creek and Lanier filter plants. Gwinnett's resident responsibility page is clear: the county maintains the meter and the small pipe from the main, and the private water service line on the customer's side belongs to the owner, along with any backflow preventer.
Duluth is a railroad-era town that grew outward with large areas of 1980s and 1990s housing, and its median home was built in 1994. Most service lines are plastic or copper laid during those build-outs, so failures usually happen at fittings, at the house connection or where later landscaping, fencing or irrigation disturbed the pipe. Gwinnett keeps a service line inventory, and you can look up your line at GwinnettCounty.com/ServiceLines.
The city's inspection list includes slab plumbing inspections, a reminder that many Duluth homes sit on slabs. If the leak seems to be at or under the slab rather than out in the yard, the plumber may need to rule out a slab leak as well.
Cost factors
- Run length. Distance from the meter to the house entry.
- What's on top. Driveways, walkways, irrigation zones and mature trees.
- Repair scope. A single joint or a damaged section that's better replaced.
- Slab entry. A line coming up through a slab can take more work at the house end.
- Permit. Trade permits are submitted through the city's GovWell portal.
What to expect on the call
This is a referral service, not a plumbing company. Your call is routed to an independent local plumber who serves Duluth. Describe where the wet ground is, when it started and whether the meter moves with the house quiet. If water is running hard, close the main valve first. If the leak is between the meter and that valve, Gwinnett can shut off service at the meter.
