How Good is Atherton Water?

In Atherton, a smaller percentage (approximately 20%) of your water supply comes from the Bear Gulch Reservoir, while a larger portion comes from the Hetch Hetchy. It’s also possible that your primary water source is a local well. Atherton water quality can vary wildly from street to street, even house by house.

Depending on your water source, your water may have an unpleasant smell or taste. The EPA overall water quality rating for Atherton is 45 out of 100 (with 100 being the best possible water quality).

Some Atherton water may be exceptionally hard —meaning high in calcium carbonate, magnesium, and even iron in some cases—which is evidenced by white deposits on your pipes, water heater, and on your dishware. If left unattended, hard water can create blockages in your pipes and can strain your appliances, shortening their longevity. Within a few short years, hard water can completely destroy your water heater.

Solutions Through De Anza

De Anza Water Conditioning, Inc. offers home water filtration systems and drinking water systems, which can soften your water and provide your home with clean, fresh drinking water. As a family owned business, we seek to cultivate lasting positive relationships with both our customers and our partners. For over 40 years we’ve been an authorized and active dealer of Kinetico Water Systems, the industry’s leading water quality solutions provider. Our Kinetico partnership allows us to offer our local customers premium products, such as water softeners, water filters, and reverse osmosis drinking water systems, just to name a few.

Don’t Underestimate the Negative Impact of Hard Water

Oftentimes, it is difficult to recognize and assess the effects of regular hard water use. It might take the premature wreckage of a water heater or some other attention-grabbing, high cost calamity before a typical water consumer takes notice.

However, if you have an eye for detail, then you can spot the impacts of hard water usage in everyday household activity. In Atherton, washing your clothes with hard water can leave them dulled in color and more susceptible to wear and tear. Your bathtub and shower will be more likely to develop dirty rings and residues that are extremely difficult to clean. Even your own hair and skin will be duller, dryer, and less healthy looking over time.

Make Life Easier, Healthier, and More Beautiful

De Anza Water Conditioning, Inc. through a partnership with Kinetico, sells a combination water filter/softener that completely removes unwanted dissolved solids in Atherton water. In addition to removing the calcium and other minerals that cause hard water, the combination water filter/softener from Kinetico also removes chlorine and chloramine, which, like hard water, can fade clothes and dry out hair and skin.
The leading-edge, patented filtration and purifying solutions from Kinetico use no electricity, but instead draw from the kinetic energy (the flow) of the water being serviced. For such impressive systems, they are incredibly simple to use and require very little upkeep. Furthermore, the Kinetico systems are confidently sold alongside extremely thorough warranties. Should you encounter any problems with your equipment, you’ll never be without support.

Atherton’s Comprehensive Water Solutions Provider

Whether it’s hard water, cloudiness, odor, or sediment deposits, or even iron or sulfuric contaminants, De Anza Water Conditioning, Inc. has an effective, simple, affordable, and guaranteed solution for you. We’re happy to offer free consultations and water tests in Atherton and the surrounding areas.

Anita W.

Honestly, over the years of calling De Anza Water for service was never a headache. They had always been responsive and came on time and when they said they would. There were never any surprises.

When I sold my house recently, I needed to fix the Reverse Osmosis unit because of a leak which was due to the housing of the unit, no big deal, really. I worked with Jennifer Administrative Assistant where she never ever left me high and dry. She responded very quickly, was completely behind what she said, and she helped schedule an appointment with the new owner. She is the best!!!

The unit is fixed and working properly! Thanks so much for the great service over the years!

Los Altos, CA

Pai P.

I was looking for a good water softener for a long time. I finally had enough with hard water for water stains and hair loss. So I started shopping around again and read some good reviews about Kinetico. DeAnza was very knowledgeable about water softener and understood my concerns about using soft water for irrigation and proposed a perfect solution to install another irrigation pipe directly to my backyard. Considering all the unique features of Kinetico and my concern was resolved, I hired De Anza water to install a refurbished system.

The system looked very nice in my garage. They showed me how to by-pass the water softener to clean the water filter and also mentioned that where the system might leak. So far the system is working perfectly and I cannot be happier with how my water now feels.

San Jose, CA

JB M.

Our family chose De Anza Water Conditioning for many reasons. They were extremely responsive to my online Yelp quote request, super friendly on the phone, and they carry a very high end product. They are an authorized dealer of Kinetico which is basically a 2 for 1 product you get soft water all the time and all of your entire homes water is filtered.

Installation was super easy and fast. Plumbing was routed very efficiently and clean looking. It took only a couple of hours to finish the install. It has been a little over a week now and we can definitely taste, feel, and see a huge difference. Soap is super bubbly, water taste is amazing, our hair is softer more clean feeling. We are really excited about our water quality now. In honesty I was not expecting this big of a difference. We don’t like to mess around drinking and showering in poor quality water. Thank you De Anza.

Mountain View, CA

Kristine L.

Requested De Anza Water to service our water softener and change out the whole house filter, and reverse osmosis water filters. When our tech arrived, he suggested the possibility of replacing our 20 year old water softer. Technology has improved the softener to use 30% less water, 30% less salt, and less energy. Sounded like a win to us. We’re glad we did it! I’ve been with De Anza Water conditioning for 20 years. We always find them to be 5 stars for us.

San Francisco, CA

Karen M.

I highly recommend De Anza Water to anyone!! Great customer service!!!

We just had to place a service call (for something we caused… we still love the Kinetico system!!). Making the appointment was easy. We really appreciate that we got a message when our technician was on his way. It had his name, photo and a link to see how far away they were and when they would arrive.

They were so thorough with everything and respectful of our property!! And provided helpful info for extending the life of the system.

Vicki A.

I was very happy with the service and support from De Anza Water conditioning. Their package and service was not the least expensive that I considered but I was impressed by the long term support they provide their customers. I had a lot of questions and our sales person Tam was patient and addressed all my concerns. Installation went smoothly and I am SO happy with the system and the quality of our water. I highly recommend De Anza Water.

San Jose, CA

Shijavi P.

Flow pressure of water is not compromised either, while ensuring great quality filtration and softening. Equipment does not use electricity either, compared to other brands that use electricity. Maintenance is not required every year for softener compared to competitors. This is a high quality product. Although expensive than other cheap brands, quality speaks for itself. In long run that additional expense does pay off.

Sunnyvale, CA

Catherine P.

I just LOVE these folks! They have serviced my water softener for the better part of the last 15 years: they are always on time, they are always thorough, the price is always what they said it would be when we scheduled the appointment, and they are always professional. Patrick came out a couple weeks ago to change the carbon. When he was doing it, he noticed a couple problems with the water softener and so he just fixed them without any extra charge.

Anna S.

We have been drinking their water since moved to California. we didn’t like the hard water and the quality, found De Anza Water and learnt that we could get water softener and filtered drinking water installed, we decided to go this path. They came out, got everything installed, Patric, the installer is extremely knowledgable and helpful, he’s really clean and efficient, got everything done in 4 hours! Now w can’t wait to take it first shower with this new water softener! If u want get good quality water, bath ur kids and take care ur water pipes, go to De Anza water!

Santa Clara, CA

We have been a client for 10 years for water softener with De Anza and very happy. After doing a lot of research, we had Kinetico RO put in for drinking water and LOVE the system. It is amazing. John came out to our house for consultation and we really learned a lot from him. The water quality Exceeded our expectation. Mike installed the unit and he was superb and we thank him for his amazing work. Thank you John, Lynne, Mike, Judy and Ian. The customer service is great. If you are really looking to get an RO system, this is it. It is expensive but WORTH IT. Every time I drink it, I think of John and how passionate he is about his work and company.
