UV Water Treatment for Wells

UV disinfection is $700 installed, all-in, and we fit it on private wells only — never city water. EPA's ultraviolet disinfection guidance names ultraviolet transmittance, meaning how clear water is to UV light, as the governing design factor, which is why filtration goes in ahead of the lamp on a well.

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

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 well owner with a lab result in hand, whose contractor has dealt with the well itself, and whose water is clear or can be made clear ahead of the chamber.
• 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.
