Water treatment Tucson experts since 1998, offering water testing, installation, softeners, reverse osmosis, and filtration with quality USA made systems. Desert Water Services, LLC is a licensed, bonded, and insured water treatment company based in Tucson, AZ. Since 1998, we have handled water treatment installation in Tucson for homes, businesses, and private wells, from free water testing and system design to installation and ongoing maintenance.
Tucson Water rates the local supply as hard to very hard, and homes we test usually show 10 to 15 grains per gallon. That hardness leaves scale on faucets, spots on dishes, and buildup inside water heaters and pipes. City water adds chlorine taste, and many wells carry sediment, iron, or a sulfur smell.
Owner Mark has 35+ years of hands-on experience and multiple certifications in water treatment.
We test hardness, TDS, pH, chlorine, and iron at your tap and explain every result in plain language.
Third party certified, USA made equipment that protects appliances and delivers long-term value.
Mark has more than 35 years of hands-on experience in water treatment and has worked as a fully licensed, bonded, and insured independent contractor for over three decades. He holds multiple certifications in water treatment technologies and only recommends proven, third party tested systems and premium products made in the USA. Desert Water Services is a family business, with Mark’s son helping on installations and service calls and his daughter supporting the business side.
Good water treatment installation in Tucson starts with a water test, not a guess. We size each system to your hardness, property size, and peak water use, install it to code, and program it for how you use water. Most residential water softener installs take two to four hours when a soft water loop is already in place. Whole house water treatment gives every faucet, shower, and appliance treated water, and many Tucson homes pair it with reverse osmosis at the kitchen sink for drinking water and ice.
For hard, chlorinated city water, we are the authorized local provider of the Reionator Pro-Series by WaterTech. Its U.S. patented dual-bed resin treats hardness, chlorine, taste, and odor in one system, and Desert Water Services offers a full money-back guarantee if it does not perform as designed. For hard, unchlorinated well water, we are an authorized Water Right dealer and install the Sanitizer Plus series.
We sell, install, and maintain home systems, including water softener installation in Tucson and water filtration in Tucson. See our residential water treatment systems.
Hard water raises maintenance costs and cuts equipment efficiency. We provide commercial water treatment for restaurants, hotels, office buildings, healthcare facilities, schools, retail businesses, and manufacturing plants.
Tucson area wells often carry high mineral content, sediment, hardness, iron, or a sulfur smell. We provide well testing, custom system design, and well water treatment.
Our water system maintenance covers inspection, filter replacement, cleaning and sanitization, performance testing, and worn part checks for softeners, RO, whole house filtration, and commercial systems, including most brands we did not install.

Reverse osmosis removes up to 99% of dissolved contaminants, including lead, arsenic, fluoride, and nitrates, for purified drinking water and ice. Explore our reverse osmosis Tucson services.
Plenty of companies will test your water, but the test is only as useful as the advice that follows it. We built our water testing Tucson service around a few things that make a real difference for the people who call us.
We test on site, not off site. Samples are pulled and analyzed at your home, so you get answers during the visit instead of waiting days for a report to land in your inbox.
Results come with an explanation. Hardness numbers, TDS readings, and pH levels mean very little on their own. We tell you what each figure means for your plumbing, your appliances, and your day to day water use.
No pressure to buy anything. Our technicians are there to test, not to run a sales script. If treatment makes sense, we’ll explain the options and the cost. If it doesn’t, we’ll say so and leave it at that.
Local knowledge of Tucson water. We work with Tucson and area water every day, including both city supply and private wells, so we know what typically shows up in this region and what’s actually unusual.
Free testing with no obligation. You can book a free water test Tucson AZ homeowners qualify for without committing to anything further, which makes it easy to get a clear picture before spending money on a softener or filtration system.
EXCELLENT Based on 37 reviews Posted on Google Michael SolomonTrustindex verifies that the original source of the review is Google. Mark is a true master of his craft. The customer service, product quality, and competitive pricing Desert Water Services provides is top tier!Posted on Google Kim BostonTrustindex verifies that the original source of the review is Google. We were fortunate to meet Mark of Desert Water Services through our builder. Since our home was under construction Mark had the added issue of coordinating with the project management team and plumber. Mark really went out of his way to install the soft water system parts at the right time to get us the very best outcome. He added a water filtration system to complete the job and we couldn't be happier with the outcome. Our first day in the new home he even came out to help us with an issue related to the contractor accidentally turning off our water to the dishwasher. We are so pleased and grateful to have met Mark! The whole system is wonderful and we have already referred friends to him. We had our first service appointment after purchasing our systems. Mark continues to offer the very highest quality service. We're so pleased with our systems!Posted on Google Sherry LeaTrustindex verifies that the original source of the review is Google. Mark rebuilt my home water treatment system five years ago which saved me many $$$. Mark works conscientiously with attention to detail. I was shocked to see he polished my water softener on the outside to make it look new. I also had him install a reverse osmosis system under my kitchen sink which he did neatly, this allows me to utilize the space underneath effectively. I can recommend Mark's work confidently.Posted on Google Gary ThomasTrustindex verifies that the original source of the review is Google. It was a pleasure working with Mark to install our RO and water treatment system at our house. I received quotes from four different vendors, and the prices varied greatly. One vendor didn’t even bother to visit the site to discuss it with me. We chose Desert Water Service because it offered the best value. During Mark’s visit, we discussed what we needed in a system. He provided several options and explained the maintenance and future costs associated with each. He clearly aimed to engineer a solution that met our needs, rather than just selling a pre-made kit like the others seemed to do. He arrived on time, did professional work, left the work site spotless, and followed up in the following days to ensure everything was functioning as expected. I highly recommend Desert Water Services based on the quality of their work for our purchase.Posted on Google robert weathersTrustindex verifies that the original source of the review is Google. Mark is a wealth of water knowledge! He just designed and installed a water system with softening, RO ice and RO drinking water for us. It is fantastic to not have to buy and lug home heavy flats of spring water anymore. It’s some of the best tasting water I’ve ever had. I cannot recommend Mark and Desert Water Services highly enough. Thank you Mark!Posted on Google AmyTrustindex verifies that the original source of the review is Google. On recommendation of a well specialist I purchased a spin filter that ‘cleans itself’ for our well water. It didn’t. Within a few months it was clogged beyond what frequent manual cleaning would improve. Consulted with several plumbers who in turn consulted with water specialists - the solutions were wide ranging and all cost prohibitive. Van Marke plumbing supply has provided great customer service so I called to gain insight into what I really needed that wouldn’t break the bank. “If we have water quality questions we call Desert Water Services. Nice guy, knowledgeable, good prices”. So I called DWS, owner Mark McCoy arranged to meet me that afternoon (👍🏻). That visit was a cursory assessment for him but I learned exactly the information I’d been seeking for a year. Once he had reviewed our well water quality results we discussed filtration options. The system was installed within two weeks (!). Filtration units are well protected and the system actually looks great - very professional. Could not be more pleased with the outcome. Quality of workmanship: outstanding. Cost: very reasonable. Satisfied ?: extremely Recommend DWS without reservation.Posted on Google Mary DuerksenTrustindex verifies that the original source of the review is Google. It was a pleasure to work with Mark. He understood my concerns and provided me with the best possible equipment solution. There was never any pressure to purchase unnecessary products. Mark was detailed in the install, explained the process at a highly professional level. He was mindful of my property and after the clean up it was like he was never there. I highly recommend Mark to everyone residential or commercial.Posted on Google George SharpTrustindex verifies that the original source of the review is Google. Couldn’t ask for a more knowledgeable and professional person than Mark- his installation of the equipment and cleanup was something you don’t often see anymore and he didn’t leave until he was certain we understood the workings of the new equipmentPosted on Google james nesciTrustindex verifies that the original source of the review is Google. I've known Mark for years. He's done plenty of work at my home and he recently installed a new whole house water softener. The installation was quick, neat and economical. His attention to detail is great (that's why I use no one else) and we've never had softer water. He knows what he's doing and he takes care of his customers. Thanks Mark!Posted on Google Carol NavarretteTrustindex verifies that the original source of the review is Google. I have known Mark since 1995 when he installed my first water softener. Loved it. We moved in 2003 and had him install the reionator once again. We have been pleased with his service and honesty. He loves this product and stands behind it.
A water treatment system helps remove contaminants, improve water taste and odor, reduce hard water issues, protect plumbing and appliances, and provide cleaner, safer water for everyday use.
Yes, many water treatment systems, especially water softeners, are designed to reduce or eliminate hard water minerals such as calcium and magnesium, helping prevent scale buildup and extending the life of appliances.
