Union City runs its own water distribution and sewer collection, buying treated water from the City of Atlanta, and its Water and Sewer Division administers a backflow and cross-connection control program. Plumbing permits come from Union City Community Development through its online iWorQ portal. Call the number on this page to be connected with a local plumber in Union City.

Who handles water, sewer and backflow for a Union City business?
The city does. Union City's Water and Sewer Division maintains its own water distribution system and buys treated Chattahoochee River water from the City of Atlanta, delivered through ten master meters. It also operates the wastewater collection system and lift stations, with about 91 miles of sewer lines. The division is at 770-306-6855 on weekdays from 8 to 5; the page doesn't list an after-hours number, so City Hall, 770-964-2288, is the fallback.
The same division administers the Backflow Prevention and Cross-Connection Control Program. The page we reviewed doesn't state the testing frequency or tester requirements, so call the division before assuming a schedule, especially before a buildout or a new irrigation or fire line.
Who fixes a leak on our property?
The business does. Union City's utility FAQ says that if the meter is turning with every fixture off, the leak is on the customer's side of the meter, that Public Works can't work on private property, and that customers should call a plumber. For a distribution building or shopping center with a long service line under pavement, that can mean leak locating before any digging. Tenants should check the lease to see whether the owner or tenant pays.
Where do we get a plumbing permit?
Union City's Community Development Office, Building Permits Division, on Union Street. Building, electrical, plumbing, HVAC and other permits are applied for through the city's iWorQ portal, and the office answers at 770-515-7950, option 1. The page doesn't mention water heaters specifically, so confirm whether a replacement needs a permit.
A short local note
Union City grew into a suburban bedroom community along I-85 and South Fulton Parkway, and its buildings are mostly newer; the median home dates to 2002. Commercial calls here tend to involve restroom fixtures, water heaters and drain clogs rather than old pipe. If anyone smells gas, leave first and call 911 and Atlanta Gas Light at 877.427.4321 from outside.
When you call, you'll be connected with an independent local plumber who takes commercial jobs in Union City. Describe the business, which fixtures are affected and your hours. Distribution buildings near South Fulton Parkway often run several shifts a day, so mention when a restroom or break room can be taken out of service.
