The Infrastructure Reality for San Antonio Homeowners
San Antonio draws its water supply primarily from the Edwards Aquifer, one of the most productive artesian aquifers in the United States, which delivers moderately hard water with calcium carbonate levels above 270 mg/L — enough to cause significant scale accumulation in tank water heaters within two to three years without annual maintenance. The February 2021 freeze event was a watershed moment for the city: the SAWS system recorded over 3,000 service calls in a single week as copper pipes in uninsulated attics, exterior walls, and garages failed simultaneously across the metro. San Antonio has a split infrastructure profile: established neighborhoods retain copper and galvanized steel in older homes, PEX in post-2000 builds from the 1950s–1990s in established neighborhoods, while newer developments use current-standard materials — and that mix, combined with expansive Taylor Marl clay — extreme seasonal movement damages slabs and the undefined, means plumbing conditions and common failure modes vary significantly by address across the city.

At 272 mg/L, San Antonio's water from the San Antonio Water System (SAWS) is among the hardest in the US, and the calcium deposits it leaves inside copper and galvanized steel in older homes, PEX in post-2000 builds systems from the 1950s–1990s in established neighborhoods are the primary driver of the hard water scale in water heaters and post-freeze supply line failures pattern that makes water treatment and annual maintenance especially important here. The dominant pipe materials in San Antonio homes are copper and galvanized steel in older homes, PEX in post-2000 builds, most installed during the 1950s–1990s in established neighborhoods. The underlying geology — expansive Taylor Marl clay — extreme seasonal movement damages slabs — directly affects buried supply and drain lines in San Antonio, particularly during seasonal moisture and temperature changes.
