Plumbing services in Union City
Atlanta's water, Union City's pipes
Union City is an in-between case. The city's Water & Sewer Division maintains its own distribution system, but it does not treat water. It buys treated Chattahoochee River water from the City of Atlanta, produced at Atlanta's Chattahoochee and Hemphill plants and delivered through ten master meters into the city's mains. The water is disinfected with chlorine, and the city's report does not list hardness. The same division runs the wastewater collection system, about 91 miles of sewer line plus lift stations. Its office line is (770) 306-6855 on weekdays; City Hall is 770-964-2288.
The meter test
The city's utility FAQ offers a simple check that every homeowner can do. Turn off every faucet and appliance, then look at the meter. If it is still turning, there is a leak on the customer's side. Public Works cannot work on private property, so the city tells customers to call a plumber for those repairs. Common culprits are a running toilet, a dripping water heater relief valve or a break in the buried line between the meter and the house.
The Progressive City
Incorporated by the Georgia General Assembly in 1908, Union City calls itself "The Progressive City." It had 26,830 residents in 2020 and sits in south Fulton County about 12 miles from downtown Atlanta, with a historic main street on Union Street and I-85, Highway 138 (Jonesboro Road), South Fulton Parkway, Roosevelt Highway and Shannon Parkway carrying most traffic. Its comprehensive plan describes it growing into a bedroom community for metro Atlanta workers. Housing is relatively young: the median home was built in 2002, though about 23% predate 1980.
Permits and backflow
Plumbing permits come from the Union City Community Development Office, Building Permits Division, on Union Street (770-515-7950, option 1), and applications go through the city's online iWorQ portal. The Water & Sewer Division also administers a backflow prevention and cross-connection control program; ask the division about testing requirements if you have an irrigation system.
Gas leaks
Atlanta Gas Light maintains the gas pipes in this part of Fulton County, while customers pay a marketer such as Gas South. If you smell gas, leave the house, then call 911 and Atlanta Gas Light at 877.427.4321 from outside.
Compared with Atlanta
The water is the same Chattahoochee supply Atlanta treats, but the pipes, meters and sewers belong to Union City, and so does the permit office. Call the number on this page and you'll be connected with an independent plumber who works in Union City.
