Why does Fresno need water treatment?
City Water Scale Buildup
Fresno city water has an average hardness of 7.5 grains per gallon which is considered hard water. You will notice this frequently as white scale buildup on your showerhead, sinks, and dishes. What you don’t notice is the effect it has on your appliances, water heater, and plumbing. These longterm issues can cost in the thousands of dollars. A water treatment system for your home gives you soft water and prevents those longterm issues.
Chlorine in Fresno City Water
The city of Fresno uses Chlorine as a disinfectant, which is great at killing potentially harmful bacteria and viruses. The city does not remove the chlorine after it treats the waters, so that chlorinated water is going straight to your tap. Chlorine is known to cause dry skin irritation and potential damage to your hair, and it makes your drinking water smell like a pool. Our systems remove chlorine before it enters your home, leaving your skin and taste buds to thank you.
Potentially Harmful Contaminants
The EWG reports on Fresno’s city water, and it shows that Nitrates, PFAS (Forever Chemicals), and arsenic are in the water. All three of these potential contaminants are below the legal limits, but they are still a cause for concern when it comes to long term health. We install reverse osmosis systems that reduce these contaminants to give you clean drinking water.

Locally Owned Fresno Water Treatment Company
Stellar Water Co is a locally owned company, with both owners living in Fresno and Madera California. We built this company because we believe that every Fresno home should have clean water without the sticker shock prices that national brands carry. Our team is local, our installers are local, and we pride ourselves in serving our area with integrity and honesty.
