Water and sewer service in Lilburn is run by Gwinnett County, so most homes have no private well pump, and we found no source showing wells are common in the city. Where a property does have one, a plumber can test the pump, switch and tank; on county water, a plumber can find what's really causing weak flow. Call the number on this page to be connected with a local plumber in Lilburn.

Signs to watch for
- A sudden house-wide loss of water
- Pressure that fades slowly over months
- Air bursts when faucets open after a shutoff
- On a well, a switch that clatters or a pump that runs without stopping
- A water bill climbing with no change in use
Most of these have causes that have nothing to do with a well. That's why testing comes before replacing anything.
Lilburn's water setup
A 2018 agreement among Gwinnett County, the county's Water and Sewerage Authority and the City of Lilburn has Gwinnett operating the water and sewer facilities that serve the city. The water comes from Lake Lanier through the Shoal Creek and Lanier filter plants. Gwinnett is responsible up to the meter; pipes and fixtures between the meter and the house belong to the owner.
The city began as a railroad town in 1890, and today's housing has a median build year of 1988, with about a quarter built before 1980. In homes of that age, aging pressure regulators and corroded fittings are common reasons for weak water, and a leak on the private service line will show up as a rising bill.
If you're not certain your home is on county water, the bill answers it. A well home will also have a pressure tank indoors and a capped casing in the yard.
If you're in one of Lilburn's older neighborhoods near Old Town, ask the plumber to look at the main shutoff valve too. Old gate valves can partly close or break internally, and they're often the hidden reason a house never seems to get full pressure.
Cost considerations
- Problem type. A regulator, a service line leak and a well pump are three different price ranges.
- Digging. A leak under hardscape costs more to reach.
- Equipment age. Older controls and tanks may be replaced together.
- Permits. Lilburn Planning and Business Services handles building permits; ask the plumber if one applies.
