Roswell has two water systems: the City of Roswell Water Utility serves part of the city and Fulton County serves the rest, and each runs its own backflow program. All sewer is Fulton County's, and the City of Roswell's Community Development Department issues trade permits. Call the number on this page to be connected with a local plumber in Roswell.

What happens when you call
You'll be connected with an independent local plumber who does commercial work in Roswell. It helps to know which water system serves the building before the call, since leak reports, backflow paperwork and billing go to different places. Your water bill tells you. Be ready to describe the business, the fixtures involved and when the space can be shut down.
Cost factors
- Whether the issue is one fixture or the building's main drain or supply
- Diagnostic work such as a camera or leak locator
- Off-hours scheduling to avoid closing
- Access in older storefronts in the historic district, where walls may hide decades of changes
- Trade permit steps with the city, which asks for a subcontractor affidavit, business license, state license and photo ID
- Backflow repairs, which on Roswell's own system only certain plumbers may do
Local conditions in Roswell
The Roswell Water Utility treats water from Big Creek and serves only part of the city, about 5,600 customers. Everyone else gets water from Fulton County, which draws on the Chattahoochee. Sewer is simpler: Fulton County handles all sewer lines in Roswell, even for buildings on city water, and its North Fulton sewer line is 404-612-3061.
The backflow rules depend on the water system. Roswell Water Utility keeps an approved tester list; testers must hold current certification and submit test forms within 30 days with before-and-after photos and a utility data tag. Only master plumbers holding a state license who have completed a specialized repair course may repair assemblies on that system (questions: 770-641-3707). For Fulton County water customers, testable devices must be tested yearly by a certified tester, repaired if needed, and reported through SwiftComply.
Roswell grew from an 1850s mill town, and the historic district around the mill ruins has some of the area's oldest buildings. The city overall is middle-aged, with a median home from 1989 and about 22% built before 1980.
Before the plumber arrives

- Find the main shutoff and clear access to it and the water heater
- List the affected fixtures and when the problem started
- Pull any past backflow test reports
- Have the lease or owner contact ready
