Gwinnett County is Grayson's water utility and its sewer connects to Gwinnett's system, though some properties may not be on municipal sewer. Either way, the drains and building sewer on your property are yours. Call the number on this page to be connected with a local plumber in Grayson.

Who handles sewer in Grayson?
The City of Grayson has no water department; its own page states that Gwinnett County is the water utility provider. City sewer projects connect to the Gwinnett County sewer system with Gwinnett's approval, but no city page says outright who provides residential sewer, and some properties may not be on municipal sewer at all. Gwinnett's rules make homeowners responsible for all plumbing between the meter and the house. If you're on public sewer and sewage is spilling from a manhole or the street, Gwinnett DWR's 24-hour dispatch is 678.376.7000. If you don't pay a sewer charge, you're likely on a private onsite system, which changes where a plumber's work ends.
Why would a brand-new Grayson house clog?
Grayson grew from fewer than 800 residents in 2000 to about 4,700 in 2020, and census survey data put the median home at 2012, with under 4% built before 1980. Drain pipe in these homes is plastic and nowhere near old enough to corrode. New houses still clog, though: grease and starchy scraps build up in kitchen lines, hair collects in showers, wipes snag in toilet drains, and sometimes construction debris such as drywall mud, grout or packaging is left in a line during the build. A belly in a newly backfilled lateral can also hold water and solids.
What can I try before calling?
- A flange plunger on a toilet or a cup plunger on a sink
- Cleaning hair from a tub or shower drain
- Clearing the disposal and running cold water
Stop and call if several fixtures are slow, water rises at another drain, a toilet gurgles when the washer drains, or the clog returns quickly. Avoid chemical openers; they seldom clear a real blockage. A plumber can open the line and, for a newer home with repeat clogs, run a camera to look for construction debris or a sag.
Local note
Routine clearing needs no paperwork. For repair work, Grayson takes building permit applications through its own online portal, and city inspections are scheduled by phone; the plumber can confirm what applies. When you call, you'll be connected with an independent plumber who covers Grayson.
