Lawrenceville's water and sewer come from Gwinnett County, and Gwinnett makes the property owner responsible for the entire sewer lateral. So a clog anywhere from your fixtures to the county main is a plumber's job. Call the number on this page to be connected with a local plumber in Lawrenceville.

How the call goes
The line connects you with an independent plumber who works in Lawrenceville. Describe what's happening: a single sink, or toilets and tubs together, and whether water has come up through a floor drain or lower fixture. That tells the plumber whether to bring a hand auger or a machine cable and jetter for the main line.
On site, the plumber locates the cleanout, opens the line and tests it with running water. If the line has clogged before, or roots or pipe fragments come back on the cable, a camera inspection can show what's causing it.
What affects cost
- Distance from an access point to the blockage
- Whether the cleanout is outdoors and accessible
- Cable, jetter and camera work, often priced separately
- Repair needs if the camera shows a break or sag
- Evening and weekend timing
Local conditions
Lawrenceville, the Gwinnett County seat, used to run its own water distribution system, but Gwinnett County's Department of Water Resources took it over at the end of 2020. Gwinnett now handles water and sewer, and its 24-hour dispatch line, 678.376.7000, takes reports of sewer problems in the street. The city still provides natural gas, electric and sanitation, so residents get two utility bills. Gwinnett's rules put the entire sewer lateral, including its connection to the county sewer, on the owner.
The housing mix is older than in much of Gwinnett. Census survey data put the median home at 1988, with about 30% built before 1980. Houses near the historic square are the most likely to have cast iron or clay drains that scale or let roots in, while subdivisions from the 1990s and 2000s mostly have plastic pipe. Permit rules for plumbing repairs go through the city's Planning & Development office, which has a Building Official; ask the plumber to confirm what applies if pipe needs replacing.
Grease is the most common cause of kitchen line clogs here, as everywhere, and the sewer authorities in the region spend real money fighting it in the public mains. At home, the fix is simple: let fats cool, scrape them into the trash and keep the disposal for small scraps only.
Short checklist
- Stop running water in the house
- Look for the cleanout cap near the foundation
- Note which fixture backed up first
- Clear access to toilets and floor drains
- Mention any chemicals already used
