Gwinnett County is the water utility for the City of Grayson and is responsible for the pipes that bring water to the meter. All piping between the meter and the home is the homeowner's, and the city takes building permit applications through its own portal. Call the number on this page to be connected with a local plumber in Grayson.

Who's responsible for the line to my house?
You are, from the meter on. Grayson's own community links page states that Gwinnett County is the water utility for the city, and Gwinnett's rule is that it handles the pipes up to the meter while everything between the meter and the home is the homeowner's. If water is coming up in the meter box, call Gwinnett's 24-hour dispatch line, 678-376-7000. If the wet ground is between the meter and the house, call a plumber.
Why would a line fail in such a new neighborhood?
Grayson is one of the youngest places in the metro. It grew from 765 residents in 2000 to 4,730 in 2020, and the median home was built in 2012, with fewer than 4% before 1980. A line that new doesn't wear out; it fails because something went wrong. Common causes are a fitting that wasn't fully seated during construction, backfill that settled in the first few years, a section left shallow after final grading, or damage from a fence, pool, patio or irrigation install. The upside is that a young line with one problem usually needs only a section repair. Some properties in the area may not be on municipal sewer, so the plumber should check for an onsite system before digging.
How is the repair handled and permitted?
The plumber confirms the leak with a meter test, traces the route and digs to the break, then replaces the failed fitting or damaged section. Under a new driveway or finished landscaping, boring a short section can save restoration costs. The City of Grayson takes building permit applications through its online iWorQ portal, though it doesn't say whether plumbing-only work uses the same path, so the plumber should confirm with City Hall. Gwinnett keeps a service line inventory at GwinnettCounty.com/ServiceLines if you want to see your line's recorded material.
Local note
Many Grayson homes have new sod and irrigation, and spring start-up is when a nicked line or irrigation tee often shows itself. A meter check with sprinklers off helps tell the two apart. When you call, you reach a referral service, not a plumbing company, which connects you with an independent local plumber who serves Grayson.
