Who handles commercial sewer repair for Lawrenceville businesses?
A Lawrenceville business owns its building sewer and grease trap; Gwinnett County owns the public main and runs the fats, oils and grease program that covers any commercial kitchen. Commercial repair usually means camera work, jetting grease-choked lines, replacing failed pipe under paving and keeping the trap within county rules.↗↗

The Lawrenceville story
Two centuries of downtown, one county sewer
Lawrenceville's square has been a courthouse town since the 1800s, and its restaurants, bars and shops now share the streets with a new wave of building. SouthLawn alone brings 600-plus residences and 15,000 square feet of other space next to the Lawrenceville Lawn.↗↗
Every one of those kitchens drains to Gwinnett's sewer, since the county has always been the sewer provider here. Warm, greasy water cools in the building sewer and coats the pipe; years of that narrow the line until a busy weekend backs it up into the dining room.↗
Street work adds pressure. Raised intersections are going in at Clayton and Pike Streets this year and at Crogan and Perry Streets in 2027, so repairs near the square often have to be timed around closures.↗

How we repair a commercial line without closing the doors
We camera the building sewer from the nearest cleanout, jet out hardened grease, and camera again to see the pipe itself. Many problems end there. Pipe that has cracked, sagged or separated gets replaced, usually by saw-cutting the paving along the run and working before or after business hours.
If the damage is in the public main or the right-of-way section, that is Gwinnett's to handle; the county's lateral policy draws the same line for businesses and homes.↗
Gwinnett's kitchen guidance also points to simple habits that keep a repaired line clear: drain screens, scraping and wiping cookware before washing, and never pouring fryer oil down a drain.↗

FAQ
Lawrenceville commercial sewer questions
Straight answers, with the rule or record behind them. Still unsure? Call and ask the crew that digs.
(678) 863-5620Does my Lawrenceville restaurant fall under Gwinnett's grease program?
Yes. Gwinnett's FOG ordinance applies to restaurants and to any business or institution with a commercial kitchen, including daycares, schools, hotels, hospitals and assisted living facilities. The FOG Management Supervisor is at 678.376.6713.
How big does a grease trap need to be for a new kitchen?
GNR's Gwinnett food service application says the county adopted a 1,500-gallon minimum grease trap for new food service facilities, pending review of the menu and equipment list. Confirm current sizing with DWR before you build.

Who pays for a sewer backup at my business?
The building sewer and grease trap are the owner's. Gwinnett owns the public main and the part of the lateral inside the right-of-way; if the blockage is only there, the county handles it.
Can the city help with a commercial sewer problem?
Not with the sewer itself. Lawrenceville runs power, gas, sanitation and stormwater, but its utility FAQ confirms Gwinnett has always been the sewer provider, so main issues go to DWR's 24-hour line.

What should kitchen staff do to keep lines clear?
Gwinnett's kitchen best practices include drain screens, scraping and dry-wiping cookware before washing, recycling fryer grease, and never pouring used fryer oil down the drain.
