What we do

Water Treatment Services in Colorado

Water Works has provided water treatment services across Colorado since 1971. From residential water purification services to commercial water filtration services, we're a team of water treatment specialists — not a catalog. Every system we install starts with a real test of your water, then we design, install, and stand behind the treatment your home or business actually needs.

Why Colorado Water Needs Treatment

Colorado's water starts as clean mountain snowmelt, but by the time it reaches your tap, it's picked up things the utility can't control. The EPA says there is no safe level of lead in drinking water — yet lead from older pipes, solder, and brass fixtures can leach into your water between the street main and your faucet, no matter what the utility does. And if you're on a private well, nobody regulates your water at all. That's why every system we install starts with a real water test — whether you need a PFAS removal system or a simple water softener, the process starts the same way.

How we work

Test First, Design Second

We've been providing water treatment services in Colorado since 1971. The process hasn't changed — because guessing at water treatment is how you end up with the wrong system.

Water Treatment Services — Your Questions

What water treatment services do you offer in Colorado?

We offer the full range — residential and commercial water softening, purification, reverse osmosis, whole-house filtration, under-sink filters, salt-free conditioners, well water treatment, PFAS removal, maintenance and repair, and municipal water consulting. Every system starts with a free on-site water test at your home or business.

How do I know which water treatment service I need?

Start with a free water analysis. We'll come to your home or business, test your water on-site, and explain the results in plain language. Your water test — not a product catalog — determines which treatment approach makes sense. Some homes need a softener, some need reverse osmosis at the kitchen tap, some need whole-house filtration, and some need a combination. We'll tell you exactly what your water needs and what it doesn't.

Is Colorado water hard?

It depends on where you live. Colorado's water starts as soft mountain snowmelt, but it picks up calcium and magnesium as it moves through the state's geology. Some cities run soft, others moderately hard, and a few very hard. The only way to know your actual hardness is a real test, which we do for free.

Do you serve businesses as well as homes?

Yes. We treat water for restaurants, hotels, medical facilities, manufacturing plants, agricultural operations, and office buildings across Colorado. Commercial water purification systems are sized differently than residential — they're built around your daily water volume, duty cycle, and specific water quality requirements. We approach each project based on what the water actually needs.

Do you service systems you didn't install?

Absolutely. Our maintenance and repair team works on any water filtration or softening system — whether we installed it or not. Filter swaps, RO service, softener repair, diagnostics, and emergency calls. If your system isn't performing the way it should, give us a call.

How much does a water treatment system cost in Colorado?

It depends entirely on your water. A basic under-sink filter might be a few hundred dollars installed. A whole-house softener with reverse osmosis at the kitchen tap runs more. The only honest answer comes after a water test — we'll explain exactly what you're paying for and why. No pressure, no upselling. If you don't need a system, we'll tell you.

What areas of Colorado do you serve?

We serve 56 cities across Colorado from four regional offices — Denver Metro, Northern Colorado, Colorado Springs Metro, and Pueblo & South Colorado. From Fort Collins to Pueblo and the Eastern Plains to the high country, we have a team near you. If you're not sure whether we cover your area, just give us a call.

What about PFAS in Colorado water?

Colorado has documented PFAS contamination, particularly in southern Colorado. The EPA finalized the first-ever enforceable PFAS drinking water limits in April 2024 — 4.0 ppt for PFOA and PFOS. If you're concerned about PFAS, we can test for it and design a reverse osmosis and carbon filtration system that brings those levels below detection.
