Peachtree Corners, GA
From Holcomb Bridge Road to the Chattahoochee
Peachtree Corners sits in the southwest corner of Gwinnett County, across the Chattahoochee from Dunwoody and southeast of Roswell. Holcomb Bridge Road runs from Roswell's busiest interchange straight into the city, which is why it sits inside a practical Roswell dispatch area even though it is in a different county.
The city became official on July 1, 2012, and had 42,243 residents in the 2020 census, making it the largest city in Gwinnett. Its roots are older. In 1967 developer Paul Duke began planning Technology Park Atlanta as the office core of a planned community in the area once known as Pinckneyville, and neighborhoods grew up around it through the 1970s and 1980s.
For an emergency plumber in Peachtree Corners, GA, that mix matters. Houses from the 1970s and 1980s are now old enough for original water heaters, supply lines and laterals to be failing, and the office and light commercial buildings in Technology Park have their own restrooms, water heaters and backflow assemblies to keep working.
Gwinnett County Rules, Not Fulton's
Roswell runs on Fulton County sewer. Peachtree Corners does not. The City of Peachtree Corners lists Gwinnett County's Department of Water Resources as its water and sanitary sewer provider, and that department also handles billing for both. Gwinnett's main water source is Lake Lanier, and the County notes it built many of its major water and sewer mains in the 1970s, just ahead of a growth spurt that made it the fastest-growing county in the country from 1986 through 1988.
Gwinnett draws the ownership line clearly. Its resident responsibility guide says the homeowner owns everything inside the house and underground up to the point of connection, which is the meter for water and the sewer stub for sewer. The sewer lateral, the water service line, the backflow preventer, any sanitary backwater device and the plumbing system all belong to the owner.
So a leak between the meter and the house, roots in the lateral before the stub, or a failed backflow device is a private repair. A broken main or a sewer overflow in the street goes to the County's 24-hour dispatch line at 678-376-7000. The County's Crooked Creek Water Reclamation Facility, which treats wastewater, is located in Peachtree Corners itself.

What to Do Before You Call in Peachtree Corners
A few checks tell you whether you need a plumber, the County, or both.
- Check the street first. If neighbors also lost water, or sewage is surfacing in the street, call Gwinnett's 24-hour dispatch at 678-376-7000.
- Close the house main. If water is spraying inside, shut the main where the line enters the house.
- Find the sewer cleanout. During a backup, a full cleanout means the blockage is downstream toward the stub. A dry one means it is inside the house.
- Check the backwater device if you have one. Gwinnett counts a sanitary backwater device as the owner's equipment, and a stuck flap can cause slow drains.
- Keep the County bill handy. Your account details help if the County needs to locate the meter or the stub.
Once the County confirms the problem is on your side, call (770) 214-4545. The repair is ours, around the clock.

Gwinnett County puts the connection point at the sewer stub. Everything from the house to that stub is the owner's lateral, so roots, cracks or a sag in that stretch are a sewer line repair, not a County job.
