What does sewer line installation involve in Lilburn, GA?
In Lilburn it usually means one of two jobs: replacing a worn-out lateral, or running a new one when a septic home ties into Gwinnett sewer. Conversions need a county Septic to Sewer Permit and a plumbing-only permit, a new line to the tap, and the old tank pumped and crushed or filled.↗↗

The Lilburn story
Old Town, where sewer and septic sit side by side
A 2022 rezoning case on Young Street, in the Old Town overlay, shows how Lilburn's sewer map actually looks. City planners noted that sewer infrastructure was available on Young Street for a proposed townhome project, while the houses next to the site were still on septic. Their report suggested the developer could provide sewer taps to those neighbours so they could convert.↗
That pattern repeats across town: a main in the street or the next lot over, and a tank in the backyard that predates it. When the tank starts failing, Georgia's rule makes the answer simple if sewer is close enough, and the job becomes a sewer line installation rather than a septic repair.↗
Cost help from the city is not coming. Lilburn's plan once aimed to win lower Gwinnett sewer connection fees as a redevelopment incentive; the 2024 update lists that item as canceled because the county did not support it.↗
On the record
- A 2022 staff report on an Old Town Lilburn rezoning on Young Street notes sewer infrastructure on Young Street and suggests sewer taps could be offered to adjacent owners to convert from septic.↗
- Lilburn's plan to seek lower Gwinnett sewer connection fees as a redevelopment incentive was marked Canceled: 'Not supported by Gwinnett County.'↗

Replacing a lateral that already runs to sewer
Not every Lilburn install is a conversion. On streets sewered since the houses were built, a lateral that has cracked in several places or lost its slope along most of its length is cheaper to replace than to patch again. We lay the new pipe to grade, add a cleanout where access is poor, and connect at the existing county stub, which remains the owner's responsibility up to and including that connection.↗
Trenchless options exist, but they need a line straight enough to pull or bore through. Mature trees and deep, curving runs on Lilburn's older lots often settle the question in favour of an open trench.

More about Lilburn
Single homes versus redevelopment sites
For one house, the paperwork is the county conversion permit and a plumbing permit. Larger Lilburn projects add a layer: the Young Street townhome case shows the city expecting a capacity certification from Gwinnett DWR, recorded easements and an approved sewer design before construction. We handle the private lateral work on those sites and coordinate with the engineer who carries the design.↗

Will the City of Lilburn reduce the connection fees?
No. The city's plan had proposed pursuing lower Gwinnett sewer connection fees, but its 2024 update marks that effort canceled because Gwinnett County did not support it.

What happens to my old septic tank?

Do I have to connect if sewer is nearby?
Under Georgia's rule, sewer within 200 feet of your property line generally requires connection, and a failing septic system must connect when it's available.

What does a new lateral cost per foot?
HomeGuide's national range is $40 to $180 per linear foot installed; Angi's 2026 Atlanta figure for full replacement runs $55 to $250 per foot.
