Gwinnett County Water Resources handles sewer in Lawrenceville, and the county makes property owners responsible for the entire sewer lateral, including its connection to the county sewer. About 30% of Lawrenceville homes were built before 1980, so many of those laterals are well past middle age. Call the number on this page to be connected with a local plumber in Lawrenceville.

What happens when you call
Calling the number on this page connects you with an independent plumber who works in Lawrenceville. Describe the symptoms, the age of the house and any earlier work on the line. The plumber will typically clear the line from a cleanout so water can drain, then camera it to find the defect, check the pipe material and measure the depth. Repair choices come after the footage.
For problems in the county's system, Gwinnett's 24-hour report-a-problem line is 678.376.7000.
Cost factors
- Depth and length of the damaged pipe
- What's above it: lawn, drive, patio, landscaping or trees
- Whether the damage reaches the connection to the county sewer, which Gwinnett still counts as the owner's
- Spot repair, lining or replacement
- Permit handling through the City of Lawrenceville's Planning & Development office; the city's specific plumbing permit rules weren't verified, so confirm with the Building Official
Local conditions in Lawrenceville
Lawrenceville is the Gwinnett County seat, one of the oldest towns in the county, with a historic courthouse square at its center. The median home dates to about 1988, and around 30% were built before 1980. Older houses near downtown may have cast iron or clay laterals that have cracked or let roots in; newer homes generally have PVC, which can sag or separate.
The city once ran its own water distribution system, but Gwinnett County took it over in 2020; sewer emergencies now go to Gwinnett as well. Gwinnett's resident-responsibility page is unusually broad: the owner is responsible for the entire sewer lateral, including where it ties into the county sewer. City FAQ material also notes that some properties in the area are not on municipal sewer and use a private onsite wastewater system instead; for those homes, the drain line to the tank is still a plumber's job.
Before the visit
- Stop water use where you can
- Locate the cleanout near the foundation
- Note which drain backed up first
- Keep people and pets away from any wastewater
- Gather any earlier camera or repair records
If the house is on a private onsite system rather than county sewer, say so when you call, and mention roughly where the tank sits, so the plumber knows which direction to run the camera.
