The problem

What’s really coming out of your tap?

Most homes deal with all three at once — and you can’t see any of them.

Chlorine & Chemicals

City water is chlorinated to kill bacteria — often more than a swimming pool. It irritates skin, eyes, and lungs, and leaves a taste and smell.

What the standards say →

Hard Water

Dissolved calcium and magnesium leave scale that clogs pipes, shortens the life of water heaters and appliances, and dries out skin and hair.

What the research shows →

Fertilizers & Pesticides

Farm runoff carries nitrate and pesticide residue into the water our cities draw from — and standard treatment isn't built to remove it.

See the EPA limits →

Soften

Filter

NSF/ANSI 42 certified coconut-shell carbon strips out chlorine, chemicals, tastes, and odors from every tap in the home.

3

Purify

A 7-stage reverse-osmosis system polishes your drinking water and adds healthy minerals back for clean, great-tasting water.

FAQ

Questions, answered honestly.

Is the water hard in Ankeny and Johnston?
Yes, somewhat. Ankeny and Johnston both buy their water from the regional system, and Des Moines Water Works aims to keep it under 150 mg/L of hardness — about 8.8 grains per gallon. Its daily plant data shows water leaving all three of its plants averaged 145 to 152 mg/L in 2025, or about 8.5 to 8.9 grains. That counts as hard on the U.S. Geological Survey scale, so you may notice spots on glasses and shower doors. Neither city publishes a separate hardness number of its own.
Isn’t the water already softened?
Yes, at the regional plants, before it reaches town. Neither Ankeny nor Johnston runs a softening plant. Lime softening happens at Fleur Drive and L.D. McMullen, and ultrafiltration plus reverse osmosis at Saylorville, the plant that serves homes north of Des Moines. The plants soften to a target, not to zero, and that’s why about 8 to 9 grains, on average, are still in the water. A home softener handles what is left. For many families that is a comfort choice, not a must.
What does a softener cost in Ankeny or Johnston?
$2,500 installed, or $2,850 with reverse osmosis at the kitchen sink. That is the whole figure — equipment, installation by a licensed local plumbing professional, taxes and a lifetime parts warranty. The instant quote gives you the number in about thirty seconds, before anyone visits. And if your free water test shows your home needs very little, we’ll tell you that too.
Where does the water in Ankeny and Johnston come from?
Both cities buy it from the regional system, but they handle it differently. Johnston buys all of its water and does no treatment of its own. Ankeny stores treated water in two wells about 2,500 feet deep during the cold months, then pumps it back out in summer when demand is high. The Saylorville plant, opened in 2011 to serve homes north of Des Moines, pulls from two wells along the Des Moines River and softens with ultrafiltration and reverse osmosis. Even so, its finished water averaged about 8.5 grains in 2025, close to the other plants.
Do you serve my town north of Des Moines?
Yes. Along with Ankeny and Johnston, we serve the Saylorville area, Polk City, Grimes, Granger, Alleman, Bondurant, Elkhart and Sheldahl, plus homes on private wells across northern Polk County. Alleman and Bondurant buy the same regional water. Grimes, Granger, Elkhart and Sheldahl run on local wells, and Polk City mixes local well water with regional water, so what your home needs can differ from town to town. On a private well in Polk County? The county tests well water for free. Don’t see your town? Call 515-305-3835 and ask.
Do you offer financing?
Yes — 0% financing is available, so you can enjoy clean water now and pay over time.

Where we install

Ankeny, Johnston and the north metro.

Ankeny and Johnston buy the same regional water. Polk City blends that water with local wells, and some nearby towns use wells alone. Outside city limits, homes may be on the county water system or a private well, so water can change from one town to the next.

Book a free in-home water test in Ankeny, Johnston or anywhere in the north metro. We’ll show you your real hardness number, even if the honest answer is that your home needs very little.
