Lawrenceville's sewer is handled by Gwinnett County's Department of Water Resources, which makes property owners responsible for the entire sewer lateral, including its connection to the county sewer. Sewer line replacement in Lawrenceville means new pipe for that private run, and about 30% of the city's homes predate 1980. Call the number on this page to be connected with a local plumber in Lawrenceville.
What happens when you call
The number on this page connects you with an independent local plumber who works in Lawrenceville. Expect a few questions about which drains are affected and how often the line has needed clearing, then a camera inspection. The footage shows the pipe material, depth, slope and every defect, which is what any honest replacement quote rests on.
The city's Building Official sits within Planning & Development, reachable at 678-407-6583. The city's specific plumbing permit rules weren't verified, so the plumber should confirm the permit type when filing.
What affects the cost
- The full length of the lateral, which is all yours under Gwinnett's rule
- Depth and slope, which decide whether a trenchless method works
- Paving, porches and trees on established lots near downtown
- Interior drain pipe replaced in the same project
- Permit and inspection
Local conditions in Lawrenceville
Lawrenceville, the Gwinnett County seat and "The Crepe Myrtle City," still runs its own gas, electric and sanitation, but water distribution moved to Gwinnett DWR in December 2020, and sewer emergencies go to the county as well. Gwinnett DWR's 24-hour dispatch line is 678.376.7000. Some properties in the area are not on municipal sewer; for those, the plumber's work is the line from the house to the tank.
The median home was built in 1988 and about 30.2% predate 1980, according to ACS 2019-2023 estimates. Older homes around the downtown square are where clay and cast iron laterals are most likely, and those tend to fail along their length. Newer homes usually have plastic that sags or cracks rather than corrodes.
Before the plumber arrives
- Run as little water as possible
- Locate and clear access to the cleanout
- Note which drain backs up first
- Gather records of earlier cleanings
- Move vehicles off the likely line route
- Confirm whether your home is on public sewer or a private system
If sewage has already come up indoors, keep children and pets away and wear gloves during cleanup. A plumber can clear the line first and then take the time to assess whether replacement is the right answer, rather than deciding in the middle of an emergency.
