Who do I call about gas in Grayson?
Grayson's gas comes through the City of Lawrenceville's utility, not Atlanta Gas Light, according to the city's new-resident information. Lawrenceville's gas emergency line is 770-963-3332. If you ever smell gas, leave the house without using switches, then call 911 and that line from outside. Confirm the utility on your gas bill.
Who handles water and sewer?
Gwinnett County is the water provider for Grayson; the city has no water department. Gwinnett's Department of Water Resources dispatch line, 678.376.7000, is answered day and night. Gwinnett is responsible for the pipes that bring water to the meter, and everything between the meter and the home is the homeowner's. Sewer lines in the area connect to the Gwinnett County system, but some properties are not on municipal sewer and use private onsite wastewater systems. If every drain backs up and you have no sewer service, the issue is on your own system.
What usually goes wrong in Grayson homes?
Grayson grew from 765 residents in 2000 to 4,730 in 2020, and its housing is very new: the median home was built in 2012 and only about 4% predate 1980. With plumbing that young, emergencies tend to be a water heater leak, a burst supply line or washer hose, or a fitting that has come apart, rather than corroded pipe.
While you wait, keep the main closed, turn off the water heater if it is involved and cut power to wet areas. If you are not on sewer, stop using water entirely during a backup. Many Grayson homes put the water heater in a garage or attic, where a small leak can spread before anyone sees it, so check ceilings and floors nearby. If a gas water heater or furnace is involved and you smell gas, do not try to relight anything; leave and call from outside.
Local note
Grayson takes building permit applications through its own online portal at City Hall (770-963-8017); whether plumbing-only work goes the same route was not confirmed, so ask the plumber. Ask about after-hours pricing when you are connected. Arrival depends on the hour and the plumber's workload, so no time is promised.
