Theory Water is a locally owned water softener installer and water filtration company in Del Rio, Texas. We grew up here, we drink this water, and we know the challenges it can cause. That's why we created Theory Water — to give our community a better, cleaner, and safer water solution.
Del Rio's water is naturally hard. It picks up minerals from the rock underground, and while the city treats it, it doesn't soften it, so the calcium and magnesium end up on your fixtures, in your water heater, and on your skin.

Hard water questions
Yes. Del Rio's city water comes from local groundwater sources, including San Felipe Springs. It's disinfected but not softened, so it carries dissolved calcium and magnesium that leave scale on fixtures, spots on dishes and buildup in water heaters. Theory Water will test your home's exact hardness for free.

A water softener removes the hardness minerals, calcium and magnesium, that cause scale. A water filter reduces chlorine, taste and odor. Theory Water's whole-home system does both, and a reverse osmosis system can be added at the kitchen sink for drinking water.
