Sugar Hill homes get water from Gwinnett County, not the city or the City of Buford, and Gwinnett is responsible only up to the meter. A leak in the pipe under your slab is the homeowner's repair. Call the number on this page to be connected with a local plumber in Sugar Hill.

Sugar Hill is a fast-growing north Gwinnett city near Lake Lanier. It mails as Buford, but water and sewer come from Gwinnett County Department of Water Resources. Gwinnett water is soft, averaging about 1.3 grains per gallon, and chlorinated. The city has no water department, though it does run its own gas utility. The fact sheet has no housing-age figures for Sugar Hill, so this page won't estimate them.
What to do now
- Turn off every faucet, appliance and sprinkler zone.
- Read the meter, wait a quarter hour without using water and read it again.
- Check toilets for silent leaks with a little food coloring in each tank.
- Note any floor areas that feel warm or look damp.
- Close the main shutoff if water is visible.
- For a water or sewer emergency on Gwinnett's side, use Gwinnett DWR's dispatch line; for leaks inside, call a plumber.
Symptom table
| Symptom | Likely cause |
|---|---|
| Warm spot on a slab floor | Hot supply line leaking under concrete |
| Meter moves, floors stay dry | Cold line leak, or the yard service line |
| Hot water runs out faster | Hot water escaping before it reaches taps |
| Laminate swelling in one area | Moisture rising through the slab |
| Sound of trickling water at night | Pressurized line leaking somewhere hidden |
Factors in the cost
- Time and equipment needed to find the leak
- Repair through the slab versus a reroute
- Floor coverings at the leak
- Water damage repair
- City permits and Gwinnett inspection where they apply
Sugar Hill's Building Services takes permit applications, and the city FAQ says Gwinnett County inspects water, sewer and fire codes.
Choosing how to fix it
Once the leak is located, the plumber will usually suggest one of two paths. A direct repair opens a small section of slab, replaces the bad piece and patches the floor; it suits a single failure in pipe that is otherwise sound. A reroute caps the buried line and runs new pipe through walls or the attic; it suits older pipe, repeat leaks or a leak under flooring that would be costly to replace. Ask which fits your house and why. Because Gwinnett inspects water and sewer work in Sugar Hill, the plumber can tell you whether an inspection will be part of the job.
