Local conditions in Lilburn
Lilburn began as a railroad town in 1890 and has since grown into a diverse southern Gwinnett suburb with a revitalized Old Town. A 2018 intergovernmental agreement between Gwinnett County, the Gwinnett County Water and Sewerage Authority and the city states that Gwinnett operates the authority's water and sewer facilities to serve the Lilburn area, and the city's FAQ refers sewer matters to Gwinnett's Department of Water Resources. Gwinnett's 24-hour dispatch line is 678.376.7000. The county's guidance puts all plumbing and pipes between the meter and the home on the homeowner.
The median home here dates to about 1988, and roughly 26% were built before 1980. Older homes near Old Town and along Lawrenceville Highway may have cast iron or clay laterals that have cracked or taken in roots. In newer neighborhoods, PVC is standard, and the typical problems are low spots from settling and damage from later work in the yard.
Cost factors
- How deep the pipe runs and where along it the damage is
- What's above it: lawn, driveway, landscaping or trees
- Section repair, liner or a new line
- Whether there's a usable cleanout
- City of Lilburn permits, through Planning and Business Services; its building permit application lists plumbing among the M.E.P. trades it covers
What to expect after you call
You'll be connected with an independent plumber who covers Lilburn. Mention which drains are acting up, the age of the home and any history of clogs. Limit water use until the visit. The plumber will typically clear the line, then camera it to find the cause, confirm the pipe material and measure the depth. If the footage shows the blockage is in Gwinnett's main rather than your pipe, the county's dispatch line is the next call. If it's your line, you'll have a clear picture of whether a small repair will hold or whether more of the pipe should be addressed.
