Requests come from all over San Antonio and the towns around it. Inside Loop 410, between the loops and out past Loop 1604, the question is the same: what is in my water, and what would fix what I am seeing? The answer starts with who supplies your water.

One figure does not fit every town
SAWS, the San Antonio Water System, gives a typical hardness of 15 to 20 grains per gallon for the water it provides. That figure is for SAWS customers. Towns and neighborhoods around the city may be supplied by other utilities, and some homes may be on private wells. Your water bill names your supplier: ask it for its annual water quality report, and use its figures. If you are on a well, the EPA advises testing it every year with a laboratory certified for drinking water testing.
Two things are the same everywhere in Texas. TCEQ’s Water Treatment Specialist rule covers anyone who installs or services water treatment equipment under contract, with Texas licensed plumbers exempt. And TCEQ’s advice on choosing equipment applies in every town: decide what you want to remove, then choose a unit certified by NSF, Underwriter’s Laboratory or the Water Quality Association for it. Permits are set by each city, so ask the installer which one applies where you live.
