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

Salt-based ion exchange removes the calcium and magnesium that cause scale — protecting your pipes, appliances, skin, and hair.

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 Waterloo water hard?
Yes, it is. Waterloo Water Works lists total hardness at 332 mg/L in its 2025 water analysis, which is about 19.4 grains per gallon — and when the Iowa DNR tested raw water from nine of the city's wells in February 2022, it ran 302 to 342 mg/L, or about 18 to 20 grains. Our free in-home test shows the number at your own tap.
Does Waterloo soften its water at the plant?
No. EPA records show Waterloo Water Works adds chlorine, fluoride and a corrosion-control phosphate blend, but no softening step, and that’s why the hardness in the ground is the hardness at your sink. The city reports its water meets every federal and state drinking water rule for 2025. A softener here is about comfort and upkeep, not safety, so if the spots and scale do not bother you, there is no rush.
How much does a water softener cost in Waterloo?
A whole-home softener is $2,500, and a softener with reverse osmosis at the kitchen sink is $2,850. That is all-in: equipment, installation by licensed local plumbing professionals we vet, schedule and stand behind, taxes and a lifetime parts warranty. Bigger homes can step up to an XL softener for $2,800, or $3,150 with RO. If you only want better drinking water, a tank RO is $800 and a tankless RO is $900. Our softeners are built from NSF/ANSI 44 certified components, and our RO systems are certified to NSF/ANSI 58.
Where does Waterloo tap water come from, and what does the city add?
It comes from 13 city wells, 75 to 225 feet deep, that draw on the sand and gravel of the Alluvial Aquifer and the limestone and dolomite of the Silurian-Devonian Aquifer, according to Waterloo Water Works' 2025 water quality report. Limestone and dolomite carry calcium and magnesium, and that is what hardness is. The city adds chlorine to keep the water safe on its way to you (it averaged 1.13 ppm in 2025) and orthophosphate (averaging 0.99 ppm) to help protect pipes from corrosion. If the chlorine taste or smell bothers you, whole-home carbon is $1,150, or $1,450 for catalytic carbon.

Where we install

Waterloo and the surrounding area.

Cedar Falls and Waverly each pump their own groundwater, and EPA records show that, like Waterloo, neither city softens it at the plant. Homes on private wells in the countryside have their own water story, and we treat those too.
