Frequently Asked Water Treatment Questions:

What is water treatment?

Water treatment is any process that improves the quality of water for a specific purpose. Reasons for improving water quality may include drinking, cooking, bathing, or other household activities.

How does water treatment work?

Water treatment works by running water through chemicals and filters to remove toxins and hazards. This is done at both the municipal level and at a private level in homes and/or businesses. While a water treatment plant may make water potable again, healthy, clean, quality water can only be truly achieved at the point of service (pos). This is because the water running to your home or business, from the municipal water supply, picks up contaminants from the pipes it runs through. In home water treatment, or POS systems, run your water through an additional set of filters and media that remove contaminants that may have both been picked up from the city water pipes and those that may not have been removed to begin with.

How many steps are in the water treatment process?

There are typically 9 steps in the municipal water treatment process: Collection, Screening and Straining, Chemical Addition, Coagulation and Flocculation, Sedimentation and Clarification, Filtration, Disinfection, Storage, and finally Distribution. Private water treatment systems for homes or businesses can have anywhere from 3 to 16 filtration stages that work to remove additional contaminants. Some of these stages include carbon, reverse osmosis, uv light, and remineralization.

We got our original Kinetico water softener and RO system from this company almost 25 gets ago. Guess what? It is still running like brand new. They come out here once a year to make sure everything is running well. Five years ago they changed the resin and the carbon. The technicians are highly trained and qualified. Unlike some other companies, they don’t try to sell stuff you don’t need. Today one of their technicians stopped by to do annual check up. Aiden was very knowledgeable about our system. Did a thorough job in checking the softener and the RO system and made some very minor tweaks and adjustments. Aiden has a great customer attitude and did a great job. I would give this company and Aiden ⭐️⭐️⭐️⭐️⭐️+ rating. Thanks.

I had an outstanding experience with Benjamin from De Anza Water Conditioning. From the moment he arrived, he was professional, knowledgeable, and incredibly friendly. He took the time to thoroughly inspect and service the system, making sure every detail was addressed properly. What really stood out was his willingness to explain everything in a clear and easy-to-understand way. He patiently walked me through how the system works, answered all of my questions, and made sure I felt completely comfortable with its operation. It's rare to find someone who is not only highly skilled but also genuinely cares about educating the customer. Benjamin didn't just finish the job and leave. He stayed to ensure everything was functioning correctly and verified that the system was working exactly as it should before wrapping up. His attention to detail, professionalism, and commitment to customer satisfaction were truly impressive. Overall, Benjamin provided some of the best customer service I've experienced in a long time. He went above and beyond, and his dedication to doing the job right was evident every step of the way. I highly recommend De Anza Water Conditioning, and if you're fortunate enough to have Benjamin assist you, you'll be in excellent hands!

I just had the Kinetico water softener system installed by De Anza Water Conditioning, Inc. I have a one car garage therefore there isn't much space, and there is no electrical near by the water pipe. The Kinetico system is compact, so it fits perfectly in the small space. Also, this system doesn't require electricity to run, so it worked out pretty well for me. Not to mention that the technician was skillful and professional. He took time to explain everything I need to know about how the system works, about soft water, about using potassium chloride instead of salt would be good for plants...etc. And he patiently answered all of my questions :-). I've also learned from the internet that this system is really efficient. It uses a lot less salt and less water as compared to other water softener systems that use electricity to run. Anyway, I'm pretty happy so far with the system and the service I received. Updated After using soft water for the very first time, I could feel my dry skin issue was almost gone. I used to have to apply lotion on my face, arms, and legs after shower, but now I feel like I don't need to anymore. Winter is usually the worst time for dry skin, so I'll wait and see. If it helps improve dry skin condition, I'm sure it would help improving hair condition as well. For that I will get opinions from my wife, probably in the next few days.

I had a great experience with Jose Hernandez from De Anza Water Company! Jose did an excellent job installing our water filter system. He was fast, professional, friendly, and very knowledgeable. Before starting the installation, Jose took the time to explain everything step by step so we knew exactly what he was going to do. After he finished, he walked me through the system again and made sure I understood how everything worked. The entire installation was smooth and efficient. I really appreciated Jose’s patience, professionalism, and excellent customer service. Highly recommend Jose and De Anza Water Company!
