Water in Overland Park

What Overland Park, KS water is really like

The geology, housing stock, and infrastructure of each community shape what comes out of the tap — and what your home needs.

Overland Park is the largest Kansas-side suburb and spans a huge range of housing ages — from 1970s and 80s neighborhoods to brand-new construction — so water concerns vary block to block. Older areas deal with decades of scale and aging service lines; new builds hit Johnson County's hard water fresh.

The chloramine taste from regional treatment is consistent across all of Overland Park, and the hard water — typically 12–18 grains per gallon — affects fixtures, water heaters, and appliances in every era of home.

Whether you're in an established neighborhood near Metcalf, off 435, or in a new build at the city's southern edge, your free test sizes the right system for your home.

Reviews from Overland Park, KS

★★★★★
“Our 1980s Overland Park home had decades of scale. The softener made an immediate difference and the RO at the kitchen tap is the best water we've had. Free install, no pressure.”

Overland Park questions

Frequently asked

Is Overland Park water hard?
Yes — Johnson County water runs hard, typically 12–18 grains per gallon, plus chloramine taste from regional treatment. A softener handles scale; whole-home filtration handles taste and sediment.
Do you work on both older and new Overland Park homes?
Yes — we install across Overland Park's full range of housing ages, from 1970s neighborhoods to brand-new builds. The free test checks hardness, chlorine, sediment, and lead risk in older homes so we size the right system.
How fast can you get to Overland Park?
Overland Park is a core Johnson County route — next-day service calls and same-week installation are standard. Call (816) 298-0839 to schedule your free test.
Why does my Overland Park water taste like chlorine?
The regional Kansas-side supply uses chloramine disinfection, which leaves a chemical taste and odor. A whole-home filtration system with activated carbon removes it at the main line so every tap runs clean.
Should I worry about lead in an older Overland Park home?
Pre-1986 homes may have lead in soldered joints or service lines. Our free test checks lead risk, and a drinking water RO system removes lead at the tap if needed. We show you the results first.
