Water 101

As you can imagine, water is a hot topic for us. In our industry, we are often asked, “What kind of water should I drink?” This is a great question, mainly because there are an abundant number of ways to get your water. Water is one of the most important things for your body. It keeps us hydrated, flushes out toxins, and has many other health benefits for our bodies. But, what type of water should you be drinking? Between spring, filtered, purified, and tap; there are just so many options for us to put into our bodies. Here’s a Water 101 guide that we hope helps you understand some of the many differences and ways to get your H20.

In the San Jose area, our tap water comes from the Delta, which is fed by the Mokelumne, Tuolumne, Sacramento, and Feather Rivers. Our tap water is carefully processed with filtration techniques and is held to strict standards. However, during the process of treatment, some of the beneficial minerals are removed. While we are proud to deliver clean water that is more than a suitable choice for drinking, others may want some extra benefits to their water. Luckily, there are other options available.


Spring water is fairly similar to tap water in the sense that it often feeds our rivers. But, it also may be captured from a natural mountain or artesian spring. When harvested correctly, spring water appears sparkling clean. This form of water is higher in minerals and may taste cleaner to some. Spring water is also rather untouched, because it comes from old reservoirs. Therefore, spring water is often regarded as one of the cleanest tasting and healthiest sources of water for our bodies.

Filtered water is more likely than not what you will find when shopping at a grocery store. Filtered water is often sourced from tap water as well, but then ran through a filtration system that removes chlorine. After this process, it is bottled and delivered to the store. Filtered water is healthy and has a great reputation, however, its drawback comes from the way it’s often packaged. Plastic bottles are not only detrimental to the environment, but also contain chemicals that are harmful to our bodies, especially if left in the sun. That’s why we recommend pouring the filtered water you purchase at the market into a glass or reusable bottle.

Finally, purified water is similar to filtered water, but it goes through a much more thorough method of filtration. Often times it is sent through reverse osmosis, distillation, or deionization. You can be sure that with purified water, you are free from drinking harmful chemicals. However, as mentioned before, some minerals are removed from the water as it’s processed.

It’s no secret that water is healthy for our bodies and its consumption is important for livelihood. While it may come in many different forms, those who drink it will find advantages and disadvantages with each type. The most important thing to know is that with San Jose Water, you are ensured a safe, and clean delivery of water service.
