Inside its service area, the City of Dallas runs water and sewer, requires backflow assemblies on all commercial and industrial connections with tests and applications due by April 1, and runs a commercial grease program. City Community Development issues plumbing permits inside city limits; Paulding County handles addresses outside. Call the number on this page to be connected with a local plumber in Dallas.

What happens when you call
You'll be connected with an independent local plumber who does commercial work in Dallas. Have the water bill handy, since some Dallas-area addresses are on Paulding County Water System rather than city water. Describe the business, the fixtures affected and when the space can be closed. Restaurants should mention their grease trap.
What affects the cost
- One fixture versus a main or service-line backup
- Grease load in a restaurant drain
- Backflow assembly type: a reduced pressure assembly for high hazards or a double check valve for low hazards
- After-hours scheduling
- Permit steps with the city, with inspections by Bureau Veritas
Local conditions in Dallas
Dallas is the Paulding County seat, a fast-growing exurb whose population roughly tripled from 2000 to 2020. Most buildings are recent; the median home dates to 2002. The city runs its own water system, about 37 miles of distribution lines inside city limits, buying treated water from Paulding County Water System. Service depends on the address, since the county also serves parts of the Dallas area.
The city's backflow program requires assemblies for all commercial and industrial water customers, and for multi-family customers on potable connections. High-hazard customers need a reduced pressure (RPZ) assembly and low-hazard customers a double check valve. Testers must be certified under the Georgia statewide program on the GAWP list, and all testing and applications must be submitted by April 1.
Public Works handles sewer cleaning, repair and main-line and service-line backups in the city, runs its own wastewater plant, and operates a commercial FOG program for restaurants. Report street or right-of-way water leaks to Water Maintenance at 770-443-8110 x 1402. Permits inside city limits come from Community Development at City Hall on East Memorial Drive, 770-443-8110 ext. 1203; outside the city, Paulding County issues them.
Before the plumber arrives
- Confirm city or county water from the bill
- Find the backflow assembly and its last test report
- Note when the grease trap was last pumped
- List the affected fixtures
Because the backflow deadline is fixed, book the test well before April so a failed assembly can be repaired and retested in time. If anyone smells gas, leave and call 911 and Atlanta Gas Light at 877.427.4321 from outside; Atlanta Gas Light owns the pipes in its metro territory regardless of which marketer sends the bill.
