Snellville businesses get water and sewer from Gwinnett County, while the City of Snellville issues building permits and does its own inspections, with plumbing subcontractors filing affidavits and a local plumbing code amendment on water efficiency. Gwinnett answers backflow questions. Call the number on this page to be connected with a local plumber in Snellville.

Snellville is an established southern Gwinnett suburb on US 78 with a small-town feel and a mix of retail centers, restaurants and medical offices around Piedmont Eastside Medical Center. The city has no water department; Gwinnett County Department of Water Resources supplies water and sewer, and the city's own permits require Gwinnett water and sewer tap receipts for new work.
First steps when plumbing fails
- Shut off the water. Gwinnett maintains the main and meter; everything on the customer's side, including the full sewer lateral, is the owner's.
- Call Gwinnett for public-side problems. Its dispatch line, 678.376.7000, takes main breaks and sewer spills at any hour.
- Protect patients, customers and stock. Close off wet areas, especially in medical suites.
- Note what's affected. One fixture or many tells the plumber where to look.
- Ask about permits up front. Snellville inspects its own work, and plumbing subcontractors file subcontractor affidavits.
Symptoms and what they usually mean
| Symptom | Likely cause |
|---|---|
| All restrooms slow at once | Blockage in the building sewer lateral |
| Hot water short in a dental or medical suite | Heater too small or failing |
| Fixtures that run after flushing | Worn flush valves |
| High water use flagged on the bill | Hidden leak past the meter |
| Scale on aerators | Not likely hardness; Gwinnett water averages about 1.3 grains per gallon, which is soft |
Cost factors
- How many fixtures or suites are involved
- Diagnostic time with a camera or leak locator
- After-hours work around appointments or business hours
- City permit and inspection steps; inspections are booked with the City Building Inspector at 770-985-3513 or 3514 with 24 hours' notice
- Fixture choices that meet Snellville's local water efficiency amendment
- Backflow device repairs after a test
For backflow, Gwinnett DWR takes questions at 678.376.4213 or DWRBackflow@GwinnettCounty.com. The sources behind this page didn't verify the county's testing schedule, so confirm it before you plan around one.
What happens when you call
You'll be connected with an independent local plumber who takes commercial calls in Snellville. Describe the business, the affected fixtures and your hours. Medical and dental offices often need work scheduled before the first appointment or after the last, so mention that up front. If the job will need a permit, the plumber files the subcontractor affidavit the city asks for.
