Grayson's water comes from Gwinnett County, but its natural gas is delivered by the City of Lawrenceville rather than Atlanta Gas Light, and the city takes building permit applications through its own portal. Plumber Atlanta is a free referral line to independent plumbers; it has no technicians. Call the number on this page to be connected with a local plumber in Grayson.

Plumbing services in Grayson
Gas leaks go to Lawrenceville
Grayson's new-resident information says gas for city residents comes through City of Lawrenceville Utilities. That matters most in an emergency. If you smell gas, leave the house first, then call 911 and the City of Lawrenceville's gas emergency line, 770-963-3332, from a safe place. Your gas bill confirms the utility.
A small town that grew fast
Grayson's incorporation was approved by the General Assembly in 1901, but most of the city is very recent. It went from 765 residents in 2000 to 4,730 in 2020, growing through suburban development along State Routes 20 and 84 in eastern Gwinnett, about 27 miles from downtown Atlanta. Main Street, Grayson City Park and Grayson High School are local anchors, and the city holds a Grayson Day Festival each year.
Some of the newest houses in the metro
The median Grayson home was built in 2012, and fewer than 4% are older than 1980. Old pipe is not the story here. The common calls are about first water heaters wearing out, PEX fittings and supply lines, pressure-reducing valves, shower and tub valves, toilets, garbage disposals, and slow or clogged drains.
Water and sewer from Gwinnett
The city says plainly that Gwinnett County is its water utility. Gwinnett draws from Lake Lanier and treats the water at its Shoal Creek and Lanier plants, and it lists hardness of roughly 1 to 2 grains per gallon, which is soft. Gwinnett owns the pipes to the meter; the homeowner owns everything from the meter to the house. Gwinnett's 24-hour dispatch is 678.376.7000, billing and customer care is 678.376.6800, and backflow questions go to its backflow office at 678.376.4213.
Sewer lines in Grayson connect to the Gwinnett County system, but some properties may not be on municipal sewer and instead use private onsite wastewater systems. Check your bill if you are unsure.
Permits
The City of Grayson takes building permit applications through its own online portal, and City Hall is at 475 Grayson Parkway (770-963-8017). Whether a plumbing-only job or a water heater swap goes through the same portal is not spelled out, so ask City Hall first. The city's own inspection process lists 770-338-8000 for scheduling city inspections.
