Locally Owned. Personally Committed to Clean Water.

At Real Water Systems, we’re more than just a water filter supplier — we’re your neighbors.

We specialize in residential and commercial water purification services, offering tailored solutions for homes, farms, offices, and everything in between.

Our Mission & Values

We’re not a big-box retailer or a franchise — and that’s exactly why customers trust us. At Real Water Systems, we focus on:

Education First

We don’t sell — we educate. You’ll always know what’s in your water and what system will solve your specific issue.

Customized Solutions

 No two homes or businesses are the same. That’s why every installation is tailored to your unique needs, not based on generic packages.

Local Service

We live and work in the same communities we serve — Diamond, Joplin, Carthage, and beyond. That means fast response times, consistent service, and accountability.

Quality-Backed Products

We only use trusted brands like Kenai and Hague, known for efficiency, durability, and superior performance.

Meet the Owner: Kolton Allen


Kolton Allen, founder and lead technician, built Real Water Systems on values he lives by every day: honesty, reliability, and hard work.


Born and raised in Southwest Missouri, Kolton understands the unique water challenges homeowners and businesses face here — from hard well water and iron stains to sulfur odors and scaling issues. After years of experience in the field, he started Real Water Systems to provide a better, more personal approach to water filtration — one rooted in education, not sales pressure.


Kolton is hands-on with every installation, test, and service call. When you work with Real Water Systems, you’re working directly with someone who’s invested in your satisfaction and long-term water quality.
