Kind Water Co installs, repairs, and maintains water softeners, whole-home filtration, and reverse-osmosis drinking water systems across the whole Quad Cities metro, on both sides of the Mississippi — Davenport, Bettendorf, LeClaire, and Eldridge in Iowa, and Moline, Rock Island, East Moline, and Silvis in Illinois. On the Iowa side, Iowa American Water's own published water quality data lists tap-water hardness at 136–350 mg/L, or 7.9 to 20.4 grains per gallon — hard to very hard — and none of it is softened before it reaches your home.
Whether you live in Davenport or Moline, Bettendorf or Rock Island, we install whole-home water softeners, carbon filtration, salt-free conditioners for city water, reverse osmosis drinking water systems, and well-water treatment. We also repair and service water softeners already in your home, including brands we did not sell, and keep systems running on a yearly maintenance plan. The people who do the work are licensed local plumbing professionals we vet, schedule, and stand behind.
If your softener has stopped working, a diagnostic service call is $199, and if you already know what's wrong, a known-issue trip is $99 plus the part. For more, see our guide to water softener repair in the Quad Cities. Yearly maintenance is $199 for a home with a tank reverse osmosis system and $249 for a home with a tankless one.
New systems start with a free in-home water test that measures hardness, iron, total dissolved solids, and a nitrate screening reading on site; bacteria, arsenic, lead, and PFAS need a certified lab, and so does a nitrate result you plan treatment around. Pricing is all-in — equipment, installation, taxes, and a lifetime parts warranty — with 0% financing and $100 off for military and first responders. The first 50 miles of travel are free; past that it's $1 a mile, quoted before you agree to anything.

If you live in Davenport or Bettendorf, you already know the signs: a chalky film on the shower glass, spots that won't wipe off the dishes, soap that never quite lathers, and a water heater that wears out faster than it should. There's a number behind all of it — straight from the utility — and even the bottom of that range counts as hard, while the top is what bluff-top Bettendorf and older central and west Davenport are living with.

Hardness is the mineral buildup that scales your pipes and shortens the life of every appliance that touches water. On top of that, municipal systems here treat with chlorine to keep the supply safe on its way to your tap, which is why so many homeowners notice a chemical taste or smell. And like much of farm-country Iowa, agricultural nitrate runoff is a growing local concern. None of this means your water is unsafe to drink. It means it's tough on your home, your skin, and your wallet, and that's exactly the kind of problem a properly built system is designed to fix.
We don't sell one box and call it a day. We size the system to your house and your water. For the typical city home in Davenport, Bettendorf, LeClaire, or Eldridge, that usually starts with a whole-home water softener to strip out the calcium and magnesium that cause scale, paired with whole-home carbon filtration to cut the chlorine taste and smell at every faucet — $2,500 installed all-in, or $2,850 with reverse osmosis included.
For drinking and cooking, our 7-stage reverse-osmosis system mounts under the kitchen sink and gives you clean, great-tasting water without the cost and plastic of bottled — and it's certified to NSF/ANSI 58 for total dissolved solids reduction. For more, see our guide to reverse osmosis drinking water in the Quad Cities. Larger homes in the newer Bettendorf and north-Scott-County subdivisions can step up to an XL or dual-tank system that keeps soft water flowing even during back-to-back showers. Prefer to skip the salt? We also install salt-free conditioners.
The utility's numbers only cover city water. If your home runs on a private well — toward Eldridge, Park View, Long Grove, or the farm stretches of rural Scott and Muscatine counties — nobody is testing that water but you, and wells here commonly add iron staining, a rotten-egg sulfur smell, and grit on top of their own hardness. We build well-water systems around what your free well test turns up: a dual-tank softener setup runs $3,650 all-in ($3,950 with RO), plus a sediment pre-filter as needed and, for water that has already tested safe, supplemental UV treatment certified to NSF/ANSI 55 Class B; iron and sulfur removal is quoted after your free test, since the right equipment depends on your levels.
Our name is our promise — water that's kind to you, kind to your home, and kind to your family. We're a family-owned company founded in 2021, and Kind Water Co is fully insured and bonded. The people who install your system are licensed local plumbing professionals we vet, schedule, and stand behind; we don't hand it off to whoever's available.
When it comes to the hardware, each Quad Cities build leans on the same proven parts — NSF/ANSI 42 certified Jacobi carbon, USA-made ResinTech resin, and a lifetime-rated ceramic-disc control valve — plumbed on full 1-inch lines that carry 28 GPM, so soft, filtered water reaches every tap with no drop in pressure, even in a busy household. The coverage matches the build quality: parts for life, media for five years, and labor for a year. We also offer 0% financing, because we believe clean water should be within reach for every homeowner, not just the few.
We install and service systems throughout the Iowa side of the Quad Cities and the communities that ring them — Davenport, Bettendorf, LeClaire, Eldridge, Park View, Walcott, Blue Grass, and the rural stretches of Scott County to the north and west. Whether you're in a riverfront condo, an established Davenport neighborhood, a new build off Middle Road, or a farmhouse on a private well, we'll come to you and tailor the system to your water. If you're nearby and don't see your town listed, reach out anyway — chances are we cover you.
The Illinois cities run their own water systems. According to EPA's Safe Drinking Water Information System, Moline (44,500 people served), Rock Island (39,018), and East Moline (21,374) each draw Mississippi River water through their own treatment plants, Silvis buys its water from Moline, and Hampton buys its water from East Moline — so the Iowa American Water hardness figures on this page do not describe them.
Beyond the Quad Cities, we also install in Cedar Rapids, Iowa City, and Marion — browse every community on our service areas page, or get the numbers first in our free Quad Cities water report. Shopping around? See how Quad Cities water softener companies compare.
Rather than guess at what your Davenport or Bettendorf tap is putting out, let us measure it on site. We'll come to your home, run a free in-home water test, walk you through exactly what we find, and recommend the right system for your house — with no pressure and no obligation. From there you'll get a free, straightforward quote. Call us at 319-319-6566, email hello@kindwaterco.com, or request your free quote online to get started.
Hard to very hard. Iowa American Water's own Typical Water Quality sheet lists total hardness of 136 to 350 mg/L — 7.9 to 20.4 grains per gallon — at the tap in Davenport, Bettendorf, LeClaire, Riverdale, and Panorama Park. Over about 7 grains counts as hard and over 10.5 very hard, so even the low end scales pipes and wears out appliances early.
No. The East River Station plant makes Mississippi River water safe to drink, but hardness passes through — that's why the delivered range runs 7.9 to 20.4 grains per gallon. Around here, softening happens at the house.
Definitely — and the utility's numbers don't apply to you, since nobody tests a private well but its owner. Around Eldridge, Park View, and rural Scott and Muscatine counties, wells commonly bring iron staining, a sulfur rotten-egg odor, and sediment along with their own hardness. We start with a free well test, then build the system to match — softening, iron and sulfur removal, a sediment pre-filter, and supplemental UV certified to NSF/ANSI 55 Class B for water that has already tested safe.
Licensed local plumbing professionals we vet, schedule, and stand behind. Kind Water Co is family-owned, insured, and bonded, and we stand behind every system from quote to startup. Your coverage runs lifetime on parts, five years on the media, and a year on labor.
Yes. We repair and service water softeners on both sides of the river, including brands we did not sell. A diagnostic service call is $199, and if you already know what's wrong, a known-issue trip is $99 plus the part. The work is done by licensed local plumbing professionals we vet, schedule, and stand behind, and the first 50 miles of travel are free, then $1 a mile, quoted before you agree.
Yes. We serve Moline, Rock Island, East Moline, Silvis, Milan, Coal Valley, and the rest of Rock Island County with the same all-in pricing and the same licensed local plumbing professionals we vet, schedule, and stand behind. The Illinois cities run their own water systems, so the Iowa American Water hardness figures on this page don't describe them. Our free in-home test measures your hardness, iron, and total dissolved solids on site, and we recommend equipment based on what it finds.
Every number on this page comes from a public record. Here is where to open each one yourself.
