Water Quality Composite Analysis

AWS has a long-term commitment to providing our customers with excellent drinking water, which has been proven through the years. Historically, SAWS and its predecessors have been rated as a superior water system since 1936. Your confidence in San Antonio’s water supply is important to us at SAWS. We are committed to providing reliable, quality water.

Public water systems, like San Antonio Water System, are required by law to report every year on the type and quantity of substances that are in our water. This law – the Safe Drinking Water Act (SDWA), amended by Congress in 1996 – has specific guidelines concerning drinking water quality, as well as methods of testing and frequency of testing. The Environmental Protection Agency (EPA) with assistance locally from the Texas Commission on Environmental Quality administers the SDWA to make sure tap water is safe to drink by restricting the presence of contaminants in public water systems.

Report a water quality concern any time of the day by calling (210) 704-SAWS (7297). For general questions or information about water quality, please call (210) 233-3546.
