Osceola is one of the very few unsoftened water systems this close to Des Moines, and it got there by an unusual route: the city abandoned its deep Mississippian wells altogether and now runs entirely on treated surface water. Eighteen treatment records sit behind that decision in the federal database. Not one of them is softening.
| Osceola at a glance | What the record shows |
|---|---|
| Who supplies the water | Osceola Water Works, PWSID IA2038038, 5,503 people served (EPA SDWIS); 2024 Census city estimate 5,585 |
| Where it comes from | Surface water, entirely. Osceola abandoned its deep Mississippian wells and no longer draws groundwater at all |
| Softened at the plant | No. EPA SDWIS lists eighteen records — chloramines, chlorine dioxide and gaseous chlorination, permanganate, granular activated carbon adsorption, ferric sulfate and cationic polymer coagulation, sand and gravity filtration, caustic soda pH adjustment and fluoridation — with no softening objective |
| Published hardness | None. The Iowa DNR sample database holds no total-hardness result for this system and the city publishes no figure. Sodium at the plant tap measured 36 mg/L on 07/09/2025 |
Groundwater systems in Iowa spend their treatment budget on minerals and metals. Surface-water systems spend it on organics, turbidity and disinfection, and Osceola's treatment list reads exactly that way: ferric sulfate and cationic polymer to coagulate suspended material, sand and gravity filtration to catch it, granular activated carbon for taste and odour compounds, then a three-part disinfection approach using chloramines, chlorine dioxide and gaseous chlorine.
That last detail matters for anyone specifying equipment. Chloramine is a more persistent disinfectant than free chlorine and takes more contact time to remove, which is why a full catalytic carbon tank rather than an ordinary carbon stage is the right specification when chloramine is present. It is a real difference in build, not a marketing distinction. Our carbon filtration guide covers what each grade of carbon actually does.
Hardness is unregulated, so it does not have to appear in a Consumer Confidence Report, and the state sample database has no total-hardness result for Osceola. We will not borrow a nearby town's figure — surface water and deep groundwater are not comparable on hardness in any case, so a Knoxville or Winterset number would be actively misleading here.
What we can say is that nothing in Osceola's eighteen treatment records removes calcium or magnesium, so whatever the reservoir hands the plant arrives at your house. Osceola has also been one of the faster-growing towns in south-central Iowa on the back of distribution-centre employment, which means a lot of newer housing stock where nobody has ever tested the water or fitted anything to it.
Eighteen records is a large treatment train for a town of 5,500, and each one is doing a job that groundwater systems never have to think about. A reservoir collects everything its watershed sends it: suspended clay after rain, algae in late summer, decaying organic matter year round. Ferric sulfate and cationic polymer clump that material together so sand and gravity filters can catch it. Granular activated carbon then takes out the taste and odour compounds algae leaves behind, which is why surface-water towns get seasonal taste complaints that well towns do not.
Only after all of that does disinfection make sense, and Osceola uses three agents rather than one. That is a well-equipped small-city plant working hard on a difficult raw water.
None of it addresses minerals, because coagulation and filtration act on particles and adsorption acts on organics — hardness is dissolved and passes straight through all of it. So the treatment intensity here says nothing at all about the hardness arriving at your house, which is a distinction worth drawing before anyone assumes a heavily treated supply must be a soft one.
Every price is all-in: equipment, installation, taxes and a lifetime parts warranty.
Annual maintenance is $199 a year for a tank-RO home and $249 for a tankless-RO home. Diagnostic service calls are $199; a known-issue trip is $99 plus the part. We offer 0% financing, and military and first responders take $100 off. Ask for the written breakdown before booking, or start one through our instant quote.
Outside the Osceola service area, rural Clarke County homes are on private wells drawing the same deep formations the city walked away from, with no coagulation, no filtration and no disinfection in front of them. That is a completely different job. Our well water system is a dual-tank build at $3,450, or $3,800 with tank RO, plus UV disinfection at $700 and sediment pre-filtration at $500 where the test calls for them. Tank RO rather than tankless on a well, because high dissolved solids cost a tankless unit its pressure. Start with free well water testing.
We are licensed and insured, and our softeners are built from NSF/ANSI 44 certified components and our reverse osmosis systems are certified to NSF/ANSI 58. Installation is handled by licensed local plumbing professionals we vet, schedule and stand behind. Pricing is published, all-in and identical for every household, and we would rather test your water than quote from an average.
With no published hardness figure and a supply that is entirely surface water, a reading at your own tap is the only honest basis for sizing anything in Osceola. We come to you, measure hardness, iron and the rest at your kitchen sink, and leave you the numbers and a written quote at no charge. Book your free in-home water test.
No figure is published. Hardness is unregulated, so it is not required in a Consumer Confidence Report, and the Iowa DNR sample database holds no total-hardness result for PWSID IA2038038. We will not borrow a nearby town's number, because surface water and deep groundwater are not comparable on hardness. A free in-home test measures your own tap.

Entirely from surface water. The city abandoned its deep Mississippian wells and no longer draws groundwater at all, which makes it unusual among towns this close to Des Moines. Sodium at the plant tap measured 36 mg/L on 9 July 2025.
Yes. Osceola's treatment list includes chloramines, which are more persistent than free chlorine and need more contact time to remove. That calls for a full catalytic carbon tank rather than an ordinary carbon stage. It is a genuine difference in how a system is built, not a sales distinction.
A Kind Water Co softener is $2,500 all-in, covering equipment, installation, taxes and a lifetime parts warranty, or $2,850 paired with reverse osmosis. A full catalytic carbon tank, the upgrade that genuinely handles chloramine, is quoted after the test. The XL build is $2,800, or $3,150 with RO. Softeners use NSF/ANSI 44 certified components and RO systems are certified to NSF/ANSI 58, with 0% financing and $100 off for military and first responders.
