Water Purification
Water purification is an essential process that removes harmful contaminants and bacteria from our drinking water. The benefits of clean drinking water cannot be overstated — it provides hydration and improves overall health, which is especially important for families with young children, elderly relatives, or anyone with a compromised immune system.
There are several types of Colorado water purification systems available, including carbon filters, reverse osmosis, and UV systems. Each offers unique benefits, but they all deliver clean, safe drinking water free from harmful contaminants. Our team can help you choose the right system for your home or business based on your specific water quality and usage needs.

Water Softening Filtration System
A water-softening filtration system is a reliable solution to the hard water problems that Colorado homeowners face every day. Hard water leaves mineral deposits on your dishes, fixtures, and showerheads — and over time, it can clog your pipes and damage water-using appliances.
Our water softeners work by exchanging the calcium and magnesium ions responsible for hardness with sodium or potassium ions. The result is soft water that lathers better, cleans more effectively, and protects your plumbing. Soft water also means less soap usage, brighter laundry, softer skin and hair, and longer-lasting appliances. We design each system around your household's water usage and the hardness level in your supply.

Residential & Commercial · Drinking water
Reverse Osmosis Filtration System
Reverse osmosis filtration systems force water through a semipermeable membrane to remove a wide range of contaminants, including dissolved solids, lead, chlorine, fluoride, and many others. The result is exceptionally clean, great-tasting drinking water from a dedicated faucet at your kitchen sink.
RO is one of the most thorough filtration methods available for residential and light-commercial use, and it's particularly effective at improving both the safety and the flavor of tap water. Our team sizes each system to match your household demand and pairs it with the right under-sink water filters for pre-filtration so the membrane lasts as long as it should.

Whole House Water Filtration System
If you're looking for a comprehensive way to purify the water in your entire home — not just at the kitchen tap — a whole house water filtration system is the answer. A point-of-entry system treats every drop of water as it enters your home, which means cleaner water for showers, laundry, dishwashing, and every other fixture.
That translates to better skin and hair, longer-lasting water heaters and washing machines, and consistently fresh water from every tap. We design whole-house systems around your specific source-water analysis so you get exactly the filtration your home needs and nothing you don't.

Well Water Filtration System
A well water filtration system is used to remove impurities from water sourced from a private well. Unlike municipal water, well water is not pre-treated by a utility — its quality depends entirely on the local geology, the depth of the well, and what's happening on the surface above it.
Common well water concerns include iron, sulfur (the rotten-egg smell), hardness, manganese, bacteria, and in some parts of Colorado, radon. We test your water and design a treatment train that addresses whatever your well is actually producing, giving you safe, clean, great-tasting water without the guesswork.

What we treat
Common Colorado water problems, solved at the source
- Hardness Removal
Hard water is caused by dissolved calcium and magnesium — two minerals that are abundant in Colorado's surface and well water. Colorado's median water hardness is 5.6 gpg (96 mg/L), classified as moderately hard, but it varies widely by region. You can explore Colorado water hardness data by city to see how your area compares.
Left untreated, hardness leaves scale on faucets and showerheads, spots on dishes and glassware, and builds up inside water heaters, dishwashers, and washing machines — shortening their lifespans. Hardness removal uses ion exchange, reverse osmosis systems, or template-assisted crystallization to take those minerals out before they reach your fixtures, leaving you with softer skin, brighter laundry, and appliances that run more efficiently for years longer.
- Iron Removal
Iron in well water causes reddish-brown staining on sinks, tubs, and laundry, and can give the water a distinct metallic taste. In some wells, iron bacteria can also cause slimy biofilm in toilet tanks and lines.
Iron removal typically uses oxidation followed by filtration — sometimes with a dedicated air-injection or chlorine-feed system ahead of a backwashing filter — to precipitate the iron out of the water so it can be rinsed to drain. A proper system eliminates the staining, removes the taste, and protects the rest of your plumbing from iron fouling.
- pH Balancing
Water that is too acidic slowly corrodes copper pipes, brass fittings, and water heaters, which can introduce copper and lead into the water you drink. Water that is too alkaline tends to scale and reduces the effectiveness of soaps.
pH balancing uses a neutralizer or a calcite/corosex contact tank to bring the water's pH into a safe, non-corrosive range — typically 7.0 to 8.0. The result is water that won't attack your plumbing, won't deposit excessive scale, and tastes noticeably cleaner.
- Radionuclide Treatment
Some Colorado wells — particularly along the Front Range and in areas with certain granitic geology — produce water with elevated levels of uranium or radium. These radionuclides are invisible, tasteless, and odorless, but long-term consumption has documented health risks.
Treatment typically uses a reverse osmosis system for drinking water, paired in some cases with a whole-house filtration system at the point of entry. The right configuration depends on the specific isotope and its concentration, which is why we always start with a certified laboratory analysis before sizing a system.
- Ozone Treatment
Ozone is one of the strongest oxidizers available for water treatment. Injected into the water as a gas, it destroys bacteria, viruses, and many other microorganisms on contact — and then quickly reverts to plain oxygen, leaving no chemical residue.
Ozone is often used on well water systems as a primary disinfectant ahead of a carbon filter, and it's also effective at breaking down iron, sulfur, and manganese so they can be filtered out downstream. For homeowners who want robust disinfection without adding chlorine or other chemicals, ozone is a clean, effective option.

Learn moreWhere Does Colorado Get Its Water?
Denver, the surrounding areas, and the majority of the cities and towns in Colorado all source water from the local mountains. The water must travel for many miles through a system of pipes before it reaches your tap. Along the way, it picks up minerals, and in some cases trace levels of treatment byproducts.
We test the water to identify chemicals, bacteria, and mineral content. Some minerals are beneficial, while others — fluoride and iron, for example — can cause health and aesthetic problems when consumed regularly over a lifetime.
Why Should I Have my Drinking Water Analyzed?
If you don't want to depend on bottled water, you have the option of refilling reusable water bottles with your household tap water. Knowing that your water is safe to drink not only provides you with peace of mind, but it can also help cut down on plastic consumption in your home or business.
Water taste and appearance can change based on its contents, and the only way to know for sure what is in your water is by scheduling a free water analysis with our experienced team.
Questions & answers
Frequently asked questions
How do I know if I need a water softener?
If you're seeing white spots on your dishes and shower doors, your skin feels dry after showering, or your soap just won't lather — those are the classic signs of hard water. Here in Colorado, water hardness varies a lot depending on where you live. Some cities run very hard, others are naturally soft. The best way to know for sure is to test your water — and we do that for free.
What's the difference between water filtration and water softening?
They solve different problems. Water filtration removes things you don't want in your water — chlorine, lead, bacteria, dissolved solids — so it's safer and tastes better. Water softening specifically targets the calcium and magnesium that cause hardness, which protects your pipes, appliances, skin, and hair. A lot of Colorado homes benefit from both, and we'll help you figure out what your water actually needs.
Is Colorado's water safe to drink?
Colorado's municipal water is treated and meets EPA standards, so yes — it's safe in the regulatory sense. But "safe" doesn't mean "problem-free." Hardness, chlorine byproducts, aging pipes, and in some areas PFAS contamination can all affect what comes out of your tap. A water analysis gives you the full picture so you can decide whether additional treatment makes sense for your home.
How often should I test my water?
If you're on city water, we recommend testing when you move into a new home, after any plumbing work, and once a year as a checkup. If you're on a well, test at least annually — and definitely after heavy rain, flooding, or any change in taste, smell, or appearance. We offer free water analysis across our entire Colorado service area, so there's no reason not to know what's in your water.
Do you service commercial properties?
Absolutely. We design and install water treatment systems for businesses all over Colorado — restaurants, hotels, medical facilities, manufacturing plants, you name it. Commercial systems are sized for higher flow rates and specific water quality requirements, so they need a different approach than residential. Give us a call and we'll set up a commercial water analysis.
What is reverse osmosis and how does it work?
Reverse osmosis pushes water through a semipermeable membrane that filters out dissolved solids, lead, chlorine, fluoride, and a long list of other contaminants. What you get is exceptionally clean, great-tasting drinking water straight from a dedicated faucet at your kitchen sink. It's one of the most thorough filtration methods out there, and it's a popular choice for Colorado homeowners who want the best possible drinking water.
How long do water treatment systems last?
It depends on your water quality, how much water you use, and how well the system is maintained. We work with manufacturers like Clack, Hydronix, AXEON, and Aldex — companies that build equipment for long-term residential and commercial use. Regular maintenance like filter and membrane replacements goes a long way. We handle routine maintenance and emergency repairs to keep every system we install running for years.
What's in my well water that I should be concerned about?
Well water isn't treated by a utility the way city water is — its quality depends entirely on your local geology, well depth, and what's happening on the surface above it. The common concerns we see in Colorado wells include iron, sulfur (that rotten-egg smell), hardness, manganese, bacteria, and in some areas, radon and radionuclides. We'll test your water and build a treatment system that addresses whatever your well is actually producing — no guesswork.
What are PFAS and should I be concerned about them in Colorado?
PFAS are what people call "forever chemicals" — they don't break down in the environment, and they've been found in water sources across the country. Colorado has documented PFAS contamination, particularly in the southern part of the state. In April 2024, the EPA finalized the first-ever enforceable limits for PFOA and PFOS at 4.0 parts per trillion. If you're concerned about PFAS, we can test for them and design a system that removes them.
Do you offer free water analysis?
Yes — free water analysis is the starting point for everything we do. We serve the entire Front Range from Fort Collins to Pueblo, the Eastern Plains, and the Rocky Mountain region. Our team comes to your home or business, tests your water on-site for hardness, pH, iron, and other common indicators, and explains the results in plain language. No pressure, no obligation — just answers.
