UV Water Treatment for Wells
A supplemental ultraviolet stage for well water that has already tested safe, installed after sediment, iron and softening.
The short answer
- Installed price and purpose: The current Class B UV unit is $700 installed for supplemental treatment of private-well water already tested safe to drink. Equipment, professional installation and taxes are included.
- Never on city water: Every municipal system in the Eastern Iowa service area already disinfects: Cedar Rapids chloraminates, while Marion and Hiawatha use plain chlorine.
- Clear water first: EPA guidance names ultraviolet transmittance as the governing design factor, so filtration is decided before the chamber; a pre-sediment filter is $500 installed.
- Lamp is a consumable: Budget a replacement lamp every six to twelve months at $300; it sits outside the parts warranty deliberately, because it is a scheduled consumable rather than a repair.
- Honest limits: Nothing is dosed into the water, so the chamber does not soften, does nothing about iron, and changes nothing at the kitchen tap.
- The well itself: The well — cap, seal, casing and grouting — is a licensed well contractor's work, and Kind Water Co does not inspect or repair wells.
The current Class B supplemental UV unit is $700 installed for a private-well supply already tested safe to drink. Water clarity and the selected model’s operating conditions determine the pretreatment and installation plan; we review laboratory results before recommending this stage.
What the equipment is and where it goes
Generically: a stainless chamber with a lamp inside a quartz sleeve, plumbed into the main line where the well line enters the house — downstream of any filtration, upstream of the split to your fixtures. Nothing is dosed into the water: no salt, no chemical, no change to taste, nothing carried to the far end of the house.
That is the honest limit of the technology. It does not soften water, does nothing about iron, and changes nothing at the kitchen tap. Those are separate line items on a well water treatment build.
Why we will not put one on a city supply
Every municipal system in our Eastern Iowa service area already disinfects, and their own reports say so: Cedar Rapids chloraminates, Marion and Hiawatha use plain chlorine, and Marengo's 2025 report prints a chlorine running annual average of 3.8 ppm against a 4.0 ppm maximum residual disinfectant level. A lamp on that line answers a question the utility has already answered. On a city supply the useful conversations are hardness and chlorine taste — see our Eastern Iowa city water guide.
Clear water first, then the lamp
EPA's UV guidance for water systems states that to maximize ultraviolet transmittance, upstream treatment should be optimized to remove soluble and particulate material as well as organics. Put plainly: what the light travels through governs the design, so filtration is decided before the chamber is.
A pre-sediment filter is $500 installed, and a private well is the legitimate use for one. If your lab result comes back with iron or sulfur, that is a larger build, and we quote it after a water test rather than publish a figure we would have to take back — the well water treatment cost guide shows how the pieces stack.
The lamp and the sleeve are consumables
Budget a lamp every six to twelve months at $300. It is a calendar item rather than a repair, and EPA's guidance is the formal version of why: regulated UV installations must account for lamp fouling and aging in their operating conditions. How a lamp looks is not a measurement of anything.
The quartz sleeve is the other half of the routine. EPA notes that UV disinfection can result in sleeve fouling where iron and manganese are present, which describes many Iowa wells. Across five years the real cost of ownership is the $700 install plus five to ten lamps at $300 each — weigh that before signing rather than after.
The well itself is not our department
A bacteria result points at the well, and the well — cap, seal, casing, grouting — is a licensed well contractor's work, not ours. We do not inspect or repair wells, and we will not quote equipment as a substitute for that work.
Iowa DNR states that every private well used for consumption should have its water tested at least once each year, and Iowa's Private Well Grants program provides free testing through your county health department. Free county testing and our guide to reading a coliform result both come before any quote from us.
The $700, itemised
| Item | Price | What that includes |
|---|---|---|
| UV system, installed | $700 | Equipment, installation by a licensed plumbing professional, taxes. Well water only |
| Replacement lamp | $300 | Every 6–12 months. A scheduled consumable, not a warranty part |
| Pre-sediment filter | $500 | Commonly specified ahead of UV on a well |
| Iron and sulfur treatment | Quoted after testing | We publish no figure — the build follows your result |
| Dual-tank well system + tank RO | From $3,950 | From $3,650 without the RO |
| Tank RO on its own | $897 | The only RO we put on a well; never tankless on a well |
| In-home water test | Free | Hardness, iron, TDS |
| Travel | Free first 50 miles | From our Des Moines or Marion office, then $1 per mile |
Warranty is our standard: lifetime parts, five years on media, one year on labor. The lamp sits outside it deliberately: it is a scheduled consumable, and calling it a warranty part would be a promise we could not keep. We are insured and bonded, 0% financing is available, military and first responders take $100 off, and our price does not expire.
Who it suits, and who should not buy one
- Suited: a private-well owner with recent laboratory results confirming an already-safe supply, suitable pretreatment and a workable lamp-care schedule for supplemental Class B UV.
- Not suited — city customers. Your utility already disinfects; there is nothing for us to sell you.
- Not yet — untested wells. With no lab result inside twelve months, the free county test is the entire next step.
- Wrong tool — taste and odor. A lamp changes neither. That job belongs to reverse osmosis at the kitchen sink.
- Wrong tool — a household that will not maintain it. Twice-a-year attention is the whole arrangement. Say so if that will not happen.
Where it gets mounted
Installation is by the licensed local plumbing professionals we vet, schedule and stand behind. The chamber goes near where the well line enters and needs an outlet close by: this is powered equipment, so no power means no operation. Most installs run a few hours where the plumbing is accessible; a buried pressure tank changes the day. Where UV goes in alongside softening or filtration it is sequenced last. Our well water guide covers that order.

Straight answers.
Does a UV system need a filter in front of it?
On a well, usually yes. EPA's UV guidance says upstream treatment should be optimized to remove particulate and soluble material so ultraviolet transmittance stays high, and it notes sleeve fouling where iron and manganese are present. A pre-sediment filter is $500 installed. Iron and sulfur builds are quoted after a water test.
What does a UV system cost to own, not just to buy?
The install is $700 all-in. After that, plan on a lamp every six to twelve months at $300 and periodic cleaning of the quartz sleeve, which fouls faster on iron-bearing water. Over five years that is the $700 plus five to ten lamps. The lamp is a consumable, so it is not covered by the parts warranty.
Why will you not install UV on city water?
Because the utility is already doing that work and their reports show it. Cedar Rapids chloraminates; Marion and Hiawatha chlorinate; Marengo's 2025 report prints a 3.8 ppm chlorine running annual average against a 4.0 ppm limit. On a municipal supply we would rather talk about hardness, chlorine taste, and the drinking tap.
Does UV replace a softener or a drinking water system?
No. A UV chamber adds nothing to the water and carries nothing downstream, so it does not soften, does not address iron, and does not change taste. A softener handles hardness for the house; a tank reverse osmosis system at $897 handles the drinking tap, and tank RO is the only RO we put on a well.
