Lawrenceville water and sewer are handled by Gwinnett County, but the city still runs its own natural gas department, which matters if you ever smell gas. Plumber Atlanta is a free referral line that connects callers with independent plumbers. Call the number on this page to be connected with a local plumber in Lawrenceville.

Plumbing services in Lawrenceville
A city gas system
Lawrenceville is one of a handful of metro cities that runs its own natural gas utility. The City of Lawrenceville Natural Gas Department, on West Pike Street, serves city gas customers, and Georgia 811 lists the city as a gas operator in Gwinnett County. Some addresses with a Lawrenceville mailing address may be on Atlanta Gas Light instead; your gas bill shows which. If you smell gas, leave the house first and call 911, then call your gas utility from outside: the City of Lawrenceville at 770-963-3332, or Atlanta Gas Light at 877.427.4321.
Water moved to Gwinnett County
Gwinnett County bought the city's water distribution system and took it over on December 1, 2020. Water service and water billing now come from Gwinnett County Department of Water Resources, while city customers still get a city bill for gas, electric and sanitation. Gwinnett draws from Lake Sidney Lanier, treats it at the Shoal Creek and Lanier plants, disinfects with chlorine and adds fluoride. Its water is soft, averaging about 1.34 grains per gallon. Homeowners can look up their service line material at GwinnettCounty.com/ServiceLines.
Gwinnett also handles sewer. It maintains the main and the meter, and everything on the customer side of the meter, plus the entire sewer lateral up to its connection with the county sewer, is the owner's to repair. Some properties are not on municipal sewer; those private onsite systems are the owner's responsibility, with Gwinnett County Environmental Health as the contact. Report water or sewer problems at 678.376.7000 and backflow questions to 678.376.4213.
The Crepe Myrtle City
Incorporated on December 15, 1821, Lawrenceville is the Gwinnett County seat, with a historic courthouse square, the Aurora Theatre and Georgia Gwinnett College within its limits. It had 30,629 residents in 2020 and lies about 27 miles northeast of downtown Atlanta along Georgia 316, GA 20 and US 29. The median home was built in 1988, and about 30% predate 1980. Near the old square, a plumber may find older drain and supply piping; in later subdivisions, water heaters, valves and laterals are the usual work.
Permits
The city's Building Official sits within Planning & Development (678-407-6583). Call that office to confirm whether your job, such as a water heater replacement, needs a city permit before work starts.
How it compares with Atlanta
An Atlanta home calls Atlanta Gas Light about a leak; many Lawrenceville homes call the city instead. Water comes from Lake Lanier rather than the Chattahoochee. Call the number on this page and you'll be connected with an independent plumber who works in Lawrenceville.
