Powder Springs sold its water and sewer systems to Cobb County Water System in 2019, and no hardness figure was readable in Cobb's reports, so test before buying a softener. Taste complaints point to a carbon filter instead. Call the number on this page to be connected with a local plumber in Powder Springs.

Signs that start the conversation
- White crust on showerheads and faucet aerators
- Dishes that come out spotted
- A chlorine smell when filling a glass or the tub
- A softener in the garage that hasn't used salt in months
- Grit in faucet screens after work on the street
Only the first two point toward hardness, and even those deserve a test before you buy anything.
Powder Springs water today
Powder Springs used to run its own water and sewer. Cobb County Water System bought the city's water distribution and wastewater collection systems, and the sale closed June 25, 2019; former city customers now get Cobb County bills. Cobb buys its treated water from the Cobb County-Marietta Water Authority, which draws on the Chattahoochee River and Lake Allatoona. Cobb's readable report noted free chlorine disinfection and added fluoride, but we couldn't find a hardness figure, so a test at your tap decides the softener question.
The city, named for its seven springs, has a small historic downtown surrounded by subdivisions built mostly from the 1980s onward. The median home dates to 1996, with about 15% built before 1980. Cobb owns the line from the main to the meter; the pipe from the meter to the house is the owner's, and that's where whole-house treatment goes. Because Cobb uses free chlorine rather than chloramine, ordinary carbon is enough for taste.
Cost factors
- Softener, carbon filter, sediment stage or a combination
- Location of the main: garage, crawl space or slab
- A drain and outlet near the install spot
- Removing or repairing an older unit
- Salt and cartridges over time
After you call
You'll be connected with an independent plumber who serves Powder Springs. Explain what you see and whether there's existing equipment. The city requires permits for all new plumbing, mechanical and gas work, residential or commercial, through its Community Development Department, so ask whether your installation needs one. If an irrigation line has a testable backflow assembly, Cobb's program requires an annual test by a county-registered tester.
Expect a straightforward recommendation. If the test shows little hardness, the plumber may suggest servicing or removing an old softener and adding carbon for taste. If it shows real hardness, a softener sized to the reading and your household's daily use is the next step, installed with a bypass so it can be serviced later.
