Your water
Nobody can tell you how hard your water is from a map
Wichita blends a reservoir with an aquifer, and USGS has measured both. They do not read the same. Everything on this page comes from a federal or state document, the source is printed beside every claim so you can go and read it, and where we could not verify something we say that instead of filling the gap.

What we can actually prove about Wichita water
Not what we believe. What a federal or state document says, with a link to the document. Four of them, because four is how many we could verify.
Wichita runs on two different waters, and they do not measure the same
The city draws from Cheney Reservoir on the surface and the Equus Beds aquifer underground. USGS has measured both. At Cheney, hardness across 44 samples ran from 130 to 220 mg/L as calcium carbonate - about 8 to 13 grains per gallon - with a median of 170. In the Equus Beds, the monitored index wells sit higher: 190 to 300 at the deep wells and 340 to 410 at one shallow well, which is 20 to 24 grains. Those are source waters, not what comes out of your tap, but they are the reason nobody can honestly quote you one city-wide number.

The blend you get is about to change, and it has not changed yet
Wichita cut the ribbon on a new 120-million-gallon-a-day plant in October 2024 to replace one that is eighty years old. It is not treating the city's water yet. It was due to start in April 2025, and the date has moved more than once - the last reason reported was a design fault in the clarifiers, the first stage of treatment. The eighty-year-old plant is still doing the job, and it can only treat a blend of the reservoir and the aquifer. The new one is built to run either source on its own. So the water in your pipes is going to change when it starts, nobody can tell you the week, and the scale on your fixtures will not tell you either. If you live here you already know about this one - the delay has been a sore point in Wichita for a while now.

Two houses a mile apart in Sedgwick County can be nothing alike
The Kansas Geological Survey sampled 297 wells, test holes, springs and municipal systems across Sedgwick County and found hardness running from 50 ppm to 2,211 ppm, chloride from 4 to 1,695, and nitrate from zero to 567. That survey is from 1965 and we are not quoting it as today's number - we are quoting it because the ground has not moved since. If you are outside a city main, what is under your land is its own question, and the only honest way to answer it is to look.

On a private well, nobody is testing it but you
KDHE does not require private well owners to test their water, and no utility is doing it for them. KDHE and K-State both recommend testing every year for coliform bacteria and nitrate, and every one to three years for the nuisance minerals that change slowly. Nitrate is the one to take seriously in farm country: the limit is 10 mg/L, it has no taste and no smell, and shallow or poorly cased wells are where it turns up. If you are on a well and have never had it tested, start there - before anyone sells you equipment.

Before anyone scares you
What we will not claim about your water
Fear is the standard sales tool in this trade. I would rather you knew the limits of what a water system does, mine included.
Hard water is a nuisance, not a hazard
Wichita treats its water to meet federal drinking water standards. Hardness wrecks water heaters, fixtures and laundry. It is not making your family sick, and we are not going to tell you it is.
A softener does not remove nitrate
Softening resin takes out calcium and magnesium. Carbon takes out chlorine and chloramine. Neither touches nitrate. On a well, a test first and then reverse osmosis at the kitchen sink is the honest answer, and I will say so even when it is the cheaper sale.
We have not read the city's own report
wichita.gov blocks automated access, so we could not open the annual water quality report and we are not going to quote a tap figure we have not seen. Open it yourself at wichita.gov/CCR, or send it to me and I will put the number on this page with the city credited.
Specifically, this site will never print
- A single grains-per-gallon figure for Wichita tap water
- That the city treats for hardness before it reaches you
- That a customer's hardness can be predicted from their address
- Any health outcome from treated water
- A hardness figure for any town whose own report we have not read
Hold everybody quoting you for a water system to the same standard. Ask them where their hardness number came from, and watch what happens.
How hard is Wichita water?
There is no one number, and this is worth understanding before anybody quotes you one. Wichita blends two sources. USGS measured hardness at Cheney Reservoir across 44 samples between October 2014 and September 2021: the range was 130 to 220 mg/L as calcium carbonate, the median 170. That is roughly 8 to 13 grains per gallon. The Equus Beds aquifer measures higher at the monitored wells — 190 to 300 at the deep index wells, 340 to 410 at one shallow one, which is 20 to 24 grains. Both figures are SOURCE water, not finished drinking water. We tried to read the city's own report for the tap figure and the city's website blocks automated access, so we are not going to pretend we have it. Every confident grains-per-gallon number for Wichita you will find online comes from a company selling softeners, and the two we checked disagreed with each other.
Is Wichita's new water treatment plant running yet?
No, and that matters more than most people selling softeners here seem to know. The city cut the ribbon on a new 120-million-gallon-a-day plant in October 2024 to replace one that is eighty years old, and it was due to begin operating in April 2025. It has not started. The start date has moved more than once, and the reason reported most recently was a design fault in the clarifiers, the first stage of treatment. So the eighty-year-old plant is still treating Wichita's water, and it can only treat a blend of the reservoir and the aquifer. The new one is built to run either source on its own. When it does start, the water in your pipes changes, and the scale on your fixtures is not going to tell you when.
Is hard water dangerous?
No. Hard water is a nuisance, not a health hazard. It shortens the life of water heaters, spots glassware, stiffens laundry and leaves soap on your skin. It is not making your family sick and nobody here is going to tell you it is. Anybody who does is selling through fear.
Is Wichita tap water safe to drink?
The city treats its water to meet federal drinking water standards and publishes the results in an annual report at wichita.gov/CCR. Meeting the legal standard is not the same thing as tasting good or being kind to your plumbing, and those are the problems a water system actually solves.
Does Wichita use chlorine or chloramine?
We do not know, and we are not going to guess. The city's own report would say, and the city's website returns an error to anything that is not a person in a browser, so we have not read it. If you open wichita.gov/CCR yourself it will tell you. What we can say is that if your water tastes of a swimming pool, a whole-home carbon filter is what deals with it either way — chloramine simply needs more carbon contact time than free chlorine does.
I am on a private well. What should I be worried about?
Testing, first. KDHE does not require private well owners to test, and no utility is doing it for you. KDHE and K-State both recommend testing every year for coliform bacteria and nitrate, and every one to three years for the nuisance minerals. Nitrate is the one that matters in farm country: the limit is 10 mg/L, it has no taste and no smell, and shallow or poorly cased wells are where it shows up. The Kansas Geological Survey sampled 297 sites across Sedgwick County and found nitrate from zero to 567 ppm and hardness from 50 to 2,211. Two neighbors can have completely different water.
Will a water softener fix nitrate?
No, and we will not tell you otherwise. Softening resin removes calcium and magnesium. Carbon removes chlorine, chloramine and taste. Neither is a nitrate treatment. Reverse osmosis at the kitchen sink is what handles nitrate and dissolved solids, which is why RO is part of the answer on a well rather than an add-on tacked onto the end of a sales call.
What is the difference between softening and filtering?
Two different jobs. Softening uses ion exchange to pull out the calcium and magnesium that cause scale. Filtering uses carbon to reduce chlorine, chloramine and the compounds behind bad taste and smell. Most whole-home systems do both in one tank, but they are genuinely separate processes, and anybody blurring them is being loose with you.
