Kind Water Co installs water softeners, whole-home filtration, and reverse-osmosis drinking water systems across Waterloo and Cedar Falls — on city water and private wells alike. And here a softener earns its keep: neither city utility softens, and USGS samples from Black Hawk County wells since 1990 show a median hardness of 271 mg/L — about 16 grains per gallon, 'very hard' on the USGS scale. Life along the Cedar River shapes the water in every Cedar Valley home, and you know the signs: white crust on the faucets, film on the shower door, spots on glasses straight out of the dishwasher, and soap that never quite lathers the way it should.
| Utilities | Waterloo Water Works (13 wells) · Cedar Falls Utilities (8 wells) |
|---|---|
| Water source | Alluvial + Silurian-Devonian aquifers |
| Hardness at the tap | Unsoftened — Black Hawk County wells run a median 271 mg/L (~16 gpg, very hard), per USGS sampling since 1990 |
| Softened at the plant? | No — neither utility softens |
Here's the honest math on Cedar Valley hardness: Cedar Falls Utilities pumps from eight wells in the Silurian-Devonian aquifer and adds only chlorine and fluoride at the well sites — no softening — and Waterloo Water Works, which draws from 13 wells in the Alluvial and Silurian-Devonian aquifers, describes no softening step in its annual water quality report either. In USGS sampling of Black Hawk County wells since 1990, hardness has measured from 177 to 456 mg/L (roughly 10 to 27 grains per gallon) — and on the USGS scale, anything over 180 mg/L counts as 'very hard.'
The Cedar Valley is ringed by working farmland on every side, so it's worth knowing what's been detected in your own water — start with your free Waterloo or Cedar Falls water report, built from public Iowa DNR and EPA testing data.
It is also a quieter cost you do not see. Scale from hard water builds inside pipes, water heaters, and appliances, shortening their life and driving up energy bills. And across Eastern Iowa, agricultural nitrate runoff from surrounding farmland has become a growing concern for many homeowners thinking about what is in their drinking water. Kind Water Co builds systems for the realities of this region, not a one-size-fits-all catalog. Our name is our promise: water that is kind to you, your home, and your family.
What we install in the Cedar Valley really comes down to where your water originates. Established neighborhoods in Waterloo and Cedar Falls run on treated city water, where the headaches are hardness and the chlorine taste and smell that come with municipal disinfection. Out on the acreages between the towns, families on private wells deal with a different set of problems entirely — rust-colored iron staining on sinks and laundry, that unmistakable sulfur 'rotten-egg' smell, and sediment that clouds the water and wears down fixtures.
Kind Water Co installs the right system for whichever situation is yours. For city homes, that usually means a whole-home softener paired with carbon filtration to strip out chlorine, finished with a 7-stage reverse-osmosis system at the kitchen sink for crisp, bottled-quality drinking water. For well homes, we build dedicated well-water packages with iron and sulfur removal, a sediment pre-filter, and UV purification to handle bacteria. Larger Cedar Valley homes can step up to XL or dual-tank systems, and anyone who prefers low-maintenance can choose a salt-free conditioner.
We are a family-owned company, founded in 2021, and we do this the right way. Every installation in Waterloo and Cedar Falls is handled by licensed, local plumbing professionals we vet, schedule, and stand behind, and every crew is fully insured and bonded.
The equipment is genuinely better, too. We build with NSF/ANSI 42 certified Jacobi carbon and USA-made ResinTech resin, run on a lifetime-rated ceramic-disc control valve, and plumb full 1-inch lines that move up to 28 GPM — so a finished system never robs your shower of pressure. As for standing behind the work, your parts are protected for as long as you own the system, the media for five years, and the labor for a year, and we make all of it reachable with 0% financing, because clean water should not be a luxury reserved for the wealthy.
Our trucks are a familiar sight across Waterloo and Cedar Falls, and we proudly serve the surrounding Cedar Valley communities as well — including Evansdale, Hudson, Janesville, and Denver. From a downtown Cedar Falls bungalow to a Hudson acreage on a private well, the local water challenges are the same family of problems, and we have the system to match each one. Cedar Falls has its own utility and its own water story — see our dedicated Cedar Falls water treatment page.

Yes. USGS samples taken since 1990 from wells across Black Hawk County — home to both cities — show a median hardness of 271 mg/L, about 16 grains per gallon, 'very hard' on the USGS scale. Neither utility softens the water: Cedar Falls Utilities adds only chlorine and fluoride at its eight wells, and Waterloo Water Works' annual report lists no softening step. Our free in-home test shows your exact number.
We do, and plenty of them. A well-fed home around Waterloo or Cedar Falls often comes with rusty iron stains, a sulfur 'rotten-egg' odor, and sediment riding along in the water. To handle that, we put together a dedicated well-water system that pairs iron and sulfur removal with a sediment pre-filter and UV purification, each piece chosen for what your well is actually doing.
Your system is installed by licensed, local plumbing professionals we vet, schedule, and stand behind, and every crew is insured and bonded. Coverage runs lifetime on parts, five years on the media, and a year on labor, and 0% financing is available if you'd rather spread the cost out.
