Who fixes a water line leak in Lawrenceville, GA?
It depends which side of the meter the leak is on. Gwinnett County has owned Lawrenceville's water distribution pipes since December 1, 2020, and maintains the main, the short pipe to the meter and the meter. The service line from the meter to the house belongs to the property owner, and that is the line we repair or replace.↗↗

The Lawrenceville story
The 2020 sale that moved the water pipes to Gwinnett
For most of its history Lawrenceville ran its own water system. In September 2020 Gwinnett commissioners agreed to buy the distribution pipes for a one-time $400,000 payment and a promise of at least $13.3 million in repairs and upgrades over ten years.↗
The city kept its wells, storage tanks and treatment plants. Customers kept their meters and meter numbers but got new Gwinnett account numbers, and a typical household was told to expect about $3.70 more a month at 5,000 gallons.↗↗
None of that changed the pipe under your lawn. Because the meter stayed put, the boundary did too: everything on the house side of that box is still the owner's to maintain.↗
On the record
- Gwinnett took ownership of Lawrenceville's water distribution system on December 1, 2020, paying $400,000 and guaranteeing at least $13.3 million of work over 10 years; the city retained its wells, tanks and treatment plants.↗

Cast iron coming out of the street, ductile iron going in
Old water mains are being replaced across the city right now. Downtown, a 6-inch cast iron main under Crogan and Perry Streets is giving way to 12-inch ductile iron, about 1,600 feet of it, with crews working only between 9 p.m. and 6 a.m.↗
In Forest Hills and Windsor Farms, the Forest Valley project swaps about 1.9 miles of aging main for new 8-inch ductile iron between August 2026 and early 2027, and Sandalwood's main replacement is already finished.↗
Those projects stop at the mains and meters, which are Gwinnett's; the line from your meter to the house is still yours. Main projects and pressure changes can show up weak spots in an older service line, so a new leak after the crews leave is worth checking quickly.

Repair, replacement and new service, step by step
We confirm the leak is on the house side by reading the meter with everything off, then call Georgia 811. In Lawrenceville the locate marks can include city gas and power as well as county water, since the city still runs its own gas and electric systems.↗
A pinhole or a failed fitting gets a spot repair. An older line that keeps failing gets replaced end to end from the meter to the house shutoff. For a new building, the Gwinnett water connection permit comes first, and the meter is set by the county.↗↗
Businesses follow the same line of ownership, but larger meters, fire lines and backflow assemblies make the owner's section bigger, so commercial work usually starts with a site walk.↗

FAQ
Lawrenceville water line questions
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Does the City of Lawrenceville still run the water system?
Not the pipes. Gwinnett County took ownership of the water distribution system on December 1, 2020. The city kept its wells, storage tanks and water treatment plants, but mains, meters and billing are now Gwinnett's.

Who is responsible for a leak between my meter and my house?
You are. Gwinnett's resident responsibility page says everything on the customer's side of the meter, including leaks between the meter and the home, is the owner's to maintain, repair or replace.
Did my meter change when Gwinnett took over?
No. The city's transition FAQ says customers kept the same meter and meter number and received a new account number, so the ownership boundary at your meter box stayed where it was.

What is the construction on Crogan and Perry Streets?
A downtown water main project replacing about 1,600 feet of 6-inch cast iron with 12-inch ductile iron pipe. The city's construction page says the work happens at night, from 9 p.m. to 6 a.m.

Will the Forest Valley project replace my service line?
The project covers about 1.9 miles of water main in Forest Hills and Windsor Farms. Mains and meters are the county's; the service line on the house side of your meter remains yours, so it is not part of main work.

HomeAdvisor's 2026 figures put trenched replacement at roughly $50–$250 per foot, and HomeGuide lists short repairs around $400–$1,500. Length, paving and access decide where a Lawrenceville job falls.
