Hiram's water is split: the city serves in and around downtown, and Paulding County Water System serves the rest, with no hardness figure stated in the report. Test before you buy a softener. Call the number on this page to be connected with a local plumber in Hiram.

Signs to look for
- Spots on glassware and crust on faucets
- A chlorine smell in drinking water
- Grit from the hot side
- A softener that a builder installed without a test
- Pressure loss after a filter went in
Hiram's water
Hiram is a small, fast-growing city on the US 278 and GA-92 corridor in south Paulding County, growing from about 1,400 residents in 2000 to nearly 5,000 in 2020. The City of Hiram provides water to customers in and around downtown; everyone else is on Paulding County Water System. The county's report, posted by the city, shows a supply from Richland Creek Reservoir, fed by pumping from the Etowah River, plus treated water bought from the Cobb County-Marietta Water Authority. It shows free chlorine disinfection and no violations, but not hardness. A test at your tap settles whether a softener makes sense.
Because the water is free-chlorinated, ordinary carbon handles taste. Paulding County Water System runs a lead and copper service line inventory project. Housing is young, with a median build year of 2004, so pipe corrosion is uncommon and most questions are about equipment choices.
Cost factors
- Equipment type and size based on the test
- Main line access, often in a garage or on a slab
- A drain and outlet nearby
- Adjusting or removing builder-installed equipment
- Recurring salt and cartridges
After you call
You'll be connected with an independent plumber who serves Hiram. Mention whether your water bill comes from the city or Paulding County. Hiram sends building permits to the Paulding County Development Division, whose Building & Permitting Division issues plumbing permits from its office in Dallas, so the plumber can confirm whether your install needs one. For county-water customers with an irrigation backflow device, Paulding requires testers on the GAWP certified list who send test forms to the county.
Most Hiram visits end with a small, specific fix: a carbon cartridge for taste, a softener only where a test shows real hardness, or a builder-installed unit reset to match your water. Because so many homes here are new, that is usually all it takes to sort out the water.
