Kind Water Co is a family-owned water softener and water treatment company installing whole-home systems in Cedar Rapids, IA — our hometown. Cedar Rapids tap water is moderately hard, typically 6 to 9 grains per gallon (about 100–150 mg/L), per the city's own water FAQ, because the city lime-softens its supply at the plant. That's a real head start — water entering the plant from the wells along the Cedar River averages about 15.8 grains before treatment — but six-plus grains is still enough to spot your glassware, film up your shower doors, and shorten a water heater's life. We grew up with this water, and it's exactly why Kind Water Co started right here.
| Utility | City of Cedar Rapids Water Department |
|---|---|
| Water source | Alluvial wells along the Cedar River |
| Hardness at the tap | 6–9 gpg (moderately hard), per the city’s water FAQ |
| Softened at the plant? | Yes — lime softening (from ~15.8 gpg raw) |
Here are the real numbers: water entering the city's plant averages about 15.8 grains per gallon — around 270 mg/L, very hard on the USGS scale — and the city's lime-softening cuts that to an average of 6.5–7 grains, per the City of Cedar Rapids' own water-softening page. At roughly 111–120 mg/L, what reaches your tap is moderately hard: softened, but not soft. Homes on private wells outside city limits don't get that head start at all, which is where our free in-home test earns its keep.
That leftover hardness is what leaves the crusty white buildup on faucet aerators and the haze on glasses straight out of the dishwasher, and it's why soap never quite lathers.
Farm country sits upstream of everyone here — nitrates and field chemicals can turn up in city water and well water alike, and your free Cedar Rapids water quality report, built from public Iowa DNR and EPA testing data, shows exactly what's been detected. And homes out past the city limits on private wells deal with their own mix of iron staining and sediment.
Every home is a little different, so we start with the water you actually have, not a one-size kit. For the classic Cedar Rapids hard-water complaint, a whole-home water softener does the heavy lifting: softer skin and hair, spotless glassware, and appliances that last the way they should. We pair it with whole-home carbon filtration when you want to cut chlorine taste and odor from city water at every tap.
For drinking and cooking, our 7-stage reverse osmosis system gives you clean, crisp water straight from a dedicated faucet at the kitchen sink. And for the many homes in the surrounding countryside on private wells, we build well-water systems that tackle iron and sulfur 'rotten-egg' smell, add UV purification, and catch sediment with a pre-filter before it ever reaches your plumbing. We also offer salt-free conditioners and dual-tank or XL setups for larger households.
We're family-owned, founded in 2021, and headquartered right here in Cedar Rapids, so when you call, you're talking to your neighbors. Here in our hometown, every system is put in by licensed local plumbing professionals we vet, schedule, and stand behind, and we carry full insurance and bonding on every job.
The equipment is built to last, too. The core of each build is NSF/ANSI 42 certified Jacobi carbon, USA-made ResinTech resin, and a lifetime-rated ceramic-disc control valve, all plumbed on full 1-inch lines that move up to 28 GPM, so a Cedar Rapids home keeps its pressure instead of paying for it with weaker showers. Behind all of it, the warranty is genuinely best-in-class: parts are covered for life, the media for five years, and labor for a full year after install. 0% financing is available, because better water shouldn't have to wait. Our name is our promise.
Cedar Rapids is home base, but we're just as at home next door. We regularly install and service systems in Marion, Hiawatha, Robins, Ely, and Fairfax, and the same hard water and rural-well realities follow the map across the corridor. Whether you're on city water in a Cedar Rapids neighborhood or on a well a few miles out, we'll match the right system to your home and your water, then stand behind it.
Guessing at what's in your Cedar Rapids water never gets you far, so let's measure it instead. We'll come to your home, run a free in-home water test right at your kitchen sink, and explain what the results mean in plain language, then recommend only what your home actually needs and hand you a straightforward quote with no pressure.
