Union City runs its own distribution system but buys treated Chattahoochee River water from the City of Atlanta, and its report doesn't list hardness. Test before buying a softener, and match any filter to a real complaint. Call the number on this page to be connected with a local plumber in Union City.

Does Union City water need a softener?
The published data can't tell you. Union City's Water & Sewer Division maintains the city's own distribution system and buys treated water from the City of Atlanta, delivered through ten master meters. Atlanta treats Chattahoochee River water at its Chattahoochee and Hemphill plants, and Union City's report lists chlorine disinfection but no hardness. A plumber can measure hardness at your kitchen tap. If it's low, spend the money elsewhere; if fixtures and the heater show heavy scale, a softener sized to the result is reasonable.
What does a filter do that a softener doesn't?
A softener trades calcium and magnesium for sodium or potassium so scale doesn't form. It does nothing for taste. A carbon filter adsorbs chlorine and some disinfection byproducts that affect taste and smell; a whole-house unit covers every tap, while an under-sink unit or reverse osmosis system covers drinking and cooking water. For families who simply want better-tasting water, a kitchen filter is the low-effort option. Before choosing one, read Union City's current water quality report, since a filter decision should rest on the latest results.
Who handles which part of the job?
Union City's utility FAQ says that if the meter turns with every fixture off, the leak is on the customer's side, that Public Works can't work on private property, and that customers should call a plumber. The same split applies to treatment: anything installed between the meter and the house is the owner's. Plumbing permits come from Union City Community Development through its online iWorQ portal, and the plumber can confirm whether your specific install requires one. The Water & Sewer Division also runs a backflow prevention and cross-connection control program, so if your home has a backflow device, ask the plumber about the city's requirements.
One local note
The median Union City home was built in 2002, so most supply piping is fairly new. When water looks rusty, the water heater is a more likely culprit than the pipes, and flushing or servicing it usually costs less than adding a filter. If the color shows on both hot and cold taps, though, it is worth having a plumber look further, since that points away from the heater and toward the supply side.
