Public water companies situated in Bexar County, collectively referred to in this report as water purveyors, are community water systems. According to the Safe Drinking Water Act, P.L. 93-523, enacted by U.S. Congress in 1974, a community water system is a public water system that serves at least 15 service connections used by year-round residences (persons inhabiting the premises) or regularly serves at least 25 year-round residences.
All water companies listed in this report are located in Bexar County and are similar in their dependence upon groundwater as their primary, if not sole source, supply. The majority of these companies withdraw water from and are totally dependent on the Edwards Aquifer as a water source. However, the Glenrose Limestone, Austin Chalk, Carrizo-Wilcox, sand, and shallow gravel formations are also utilized for the production of drinking water.
The Groundwater Resource Protection Section of San Antonio Water System has compiled this list. All information has been obtained from the most recent field surveys as conducted by the Water Utilities Division of the Texas Commission on Environmental Quality (TCEQ).
The listings reflect information available as of Jan. 1, 2006 and are subject to continual revision.
