What does sewer line repair look like in Grayson, GA?
Sewer line repair in Grayson usually means a young lateral: the city had little sewer until recent years, and the median home dates to 2012. The owner keeps the pipe from the house to Gwinnett DWR's connection in the right-of-way. We camera it, find the sag, break or blockage, then dig and repair.↗↗↗

The Grayson story
A town that grew up on tanks is plugging into county mains
Grayson's comprehensive plan is blunt about it: without sewer, the city could not support much beyond detached houses, and a Gwinnett Water Resources flyer the city hands out still says many homes here run on septic. That is changing street by street. Mains now serve the M-1 industrial district, and the plan asks Gwinnett to push lines further, with the Uptown Center named as a priority.↗↗
So a Grayson sewer problem rarely looks like the root-choked clay of an old in-town neighborhood. The census estimate puts the typical home here at about fourteen years old. What goes wrong with a young plastic lateral is mostly about how it was laid: backfill that settled and let the pipe sag, a joint that was never fully seated, a line crushed by equipment during a later driveway or patio job, or a tie-in that was set too flat to carry solids.↗
On the record
- Grayson's 2024 plan calls for working with Gwinnett County to expand sewer service, especially around the Uptown Center.↗

Warning signs
Clues that a newer Grayson lateral has a defect
Seeing two or more of these? Call before it gets worse.
- 1. Toilets flush sluggishly across the house even though the plumbing is only a decade or so old.
- 2. Paper and solids keep catching at the same distance when the line is snaked.
- 3. A dip or soft trough in the lawn above the pipe route after a wet spell.
- 4. Water backs up at the outdoor cleanout during heavy laundry days.
- 5. Problems began right after landscaping, a fence or a driveway widening.
More about Grayson
Switching a Grayson house from septic to sewer
Georgia's on-site sewage rule says a building must connect when public sewer is available within 200 feet of the property line or in an abutting right-of-way, and a failing septic system has to connect once sewer is there. In Grayson that rule matters more each year as mains extend.↗
Gwinnett's written conversion procedure asks for a DWR Septic to Sewer Permit and a Plumbing Only permit before work begins. The old tank cannot stay as it is: it gets pumped empty and then crushed, or filled with concrete or gravel, and the plumbing permit carries two inspections. That document is titled for unincorporated Gwinnett, so we confirm the current steps with DWR for a city address before scheduling.↗

More about Grayson
Residential lines versus the Brannan Boulevard industrial park
Houses in Dove Lake or along Rosebud Road need a single lateral fixed or connected. The industrial park is a different job: the plan says sewer was designed throughout it as of 2023 so businesses can leave their individual septic systems as those age. Any business there with a commercial kitchen also falls under Gwinnett's fats, oils and grease ordinance, which shapes how the new line and its grease trap are laid out.↗↗
FAQ
Grayson sewer line questions
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Is my Grayson home on sewer or septic?
Many Grayson homes remain on septic, per the Gwinnett flyer the city publishes. A Gwinnett water bill showing no sewer charge is a strong sign you are on a tank.

Who fixes a sewer backup at a Grayson house?
Call DWR at 678.376.7000 first. The county handles the main and the right-of-way piece; the rest of the lateral is the owner's.

Sewer just came down my street. Do I have to connect?
State rules require connection when sewer is within 200 feet of the property line or in an abutting right-of-way, and a failing septic system must connect when sewer is available.
Source: Ga. Comp. R. & Regs. 511-3-1 (On-Site Sewage Management Systems)
What does Gwinnett charge to hook up a house?
For a 3/4-inch residential meter, the sewer development charge is $4,147, plus a $25 setup fee, before any contractor work.
Why would a lateral under a 2012 house fail?
Age is rarely the cause on newer lines. Settled backfill, a flat grade or damage from later yard work are more typical, and a camera shows which.
What happens to my old tank when I switch to sewer?
Gwinnett's procedure requires it to be pumped out and crushed or filled with concrete or gravel, with an inspection after.

Can the county reimburse part of my repair?
Only if the sole blockage is in the right-of-way section, and DWR must see the excavated lateral before the repair.
