Cleaner water from every tap. No salt. No hassle.
San Antonio sits on one of the most productive aquifers in the world — but limestone-rich groundwater means some of the hardest municipal water in Texas. LifeSource filters and conditions your water at the point of entry, so every tap delivers cleaner, better-tasting water without the salt, waste, or maintenance of a traditional water softener.
San Antonio's water comes primarily from the Edwards Aquifer, one of the most productive artesian aquifers in the world. The water percolates through limestone formations, picking up calcium and magnesium along the way. It's treated by the San Antonio Water System (SAWS) to meet federal standards, but what's legal isn't always what you'd choose to drink.
| Key Contaminant | San Antonio Level | Context |
|---|---|---|
| Hardness | 15–20 GPG | "Very Hard" (EPA: >10.5 GPG) |
| Calcium | 61–103 ppm (2011 report) | Primary hardness mineral from limestone aquifer |
| Magnesium | 11–21 ppm (2011 report) | Secondary hardness mineral from limestone aquifer |
| Chlorine | Present | Used for disinfection; affects taste & smell |
| TDS (Total Dissolved Solids) | 242–356 mg/L (2011 report) | Higher TDS = more mineral content |
San Antonio mineral values per SAWS 2011 Water Quality Report; Edwards Aquifer chemistry is stable.

LifeSource installs a whole-house water filtration and conditioning system at the point of entry to your home. Every faucet, shower, and appliance gets filtered, conditioned water.
Reduces chlorine, sediment, and other common contaminants found in San Antonio municipal water. Carbon-based media, no chemicals added.
Addresses hard water scale without salt, brine discharge, or wastewater. Minerals stay in your water. The scale doesn't stay on your fixtures.
Installed at the main water line. Every tap, every shower, every appliance. One system replaces the patchwork of under-sink filters, shower filters, and fridge filters.

| Maintenance | Minimal Regular Maintenance | Salt refills, resin replacement |
| Warranty | Lifetime | Typically 1–10 years |
Traditional water softeners discharge salt brine into municipal wastewater systems. That brine is expensive and difficult to remove during treatment, and it can damage the environment when it reaches rivers, lakes, and groundwater.
Texas context:
Texas has no restrictions on salt-based water softeners. But many San Antonio homeowners are choosing salt-free alternatives to avoid the ongoing cost of salt, the hassle of maintenance, and the environmental impact of brine discharge — especially in a region where water conservation matters. San Antonio has some of the most progressive water conservation policies in Texas, and reducing unnecessary wastewater aligns with that community priority.
LifeSource systems use no salt and produce zero brine discharge, making them fully compliant with all current and future state water softener regulations.
Real reviews from LifeSource customers in the San Antonio area.
We are thrilled with our new system. No more staining in toilet bowls, the water is crystal clear, and there are no water spots or scale build-up on any sink, faucet or shower. I spent months looking at other systems, from Kinetico to Delta. The LifeSource system was the only option for us. This is truly the best investment we have ever made. It has by far exceeded our expectations.
The system is very good. My family and I noticed a difference right away. The shower heads used to be filled with crud; once I cleaned them and put them back on, everything cleared up. It tastes and feels great!
I am extremely impressed with the taste of the water. It is hard to believe that the LifeSource system can clean the water to that level of good. What makes me unhappy is that we waited this long to get the system.
