Dacula's sewer comes from Gwinnett County's Department of Water Resources, but the city's own permit application notes that some homes are not on municipal sewer and use private onsite wastewater systems. Sewer line replacement in Dacula means new pipe for the lateral to Gwinnett's sewer or for the line from the house to the tank. Call the number on this page to be connected with a local plumber in Dacula.

Signs it's more than a clog
- Every fixture slows at once
- The lowest drain in the house is the first to back up
- Toilets gurgle as the washer empties
- A soggy or sunken path where the pipe runs
- On a private system: the tank has room, but the house still backs up
When the tank isn't full and the house still floods, look at the pipe between them, which is plumbing work. Problems in the tank or drain field go to a different trade.
Local conditions in Dacula
Dacula is a small, historic eastern Gwinnett town that is growing fast, with new retail around Harbins Road and the large Hamilton Mill area sharing its 30019 ZIP. The city's Non-City Utilities page lists Gwinnett County for water and sewer, and Gwinnett has built sewer lines in Dacula, such as the Maxey Street project. If you are on Gwinnett sewer, the county's 24-hour dispatch is 678.376.7000, and the lateral from your house is yours to maintain. The city's permit application notes that new structures on lots without sewer need Gwinnett Environmental Health approval.
The median home dates to 1999 and about 12.5% predate 1980, according to ACS 2019-2023 estimates, so most lines are plastic. Settling, shifted joints and damage from later digging are the usual reasons they fail.
What affects cost
- Distance to the county sewer or the tank inlet
- Depth and slope of the existing pipe
- Driveways, fences and landscaping on the route
- Interior drain pipe replaced at the same time
- Coordination if the tank inlet also needs work
What happens when you call
You'll be connected with an independent local plumber who works in Dacula. Expect to be asked where your wastewater goes, then a camera inspection. The City of Dacula issues its own building permits, picked up and paid for at City Hall on Harbins Road, and the City Inspector inspects with 24 hours' notice. The permit application's plumbing rough inspection includes a water test on waste lines, which the new pipe will need to pass before it's buried. In Hamilton Mill and other newer neighborhoods, irrigation and invisible fences are common, so mark them before digging begins.
