Texas Commission on Environmental Quality (TCEQ) recently notified SAWS that two systems added in recent years–the Concept Therapy Institute (CTI) and S&S Hills systems–were upgraded to “Superior Public Water Systems.” SAWS City of San Antonio water system has been rated Superior since 1936.

TCEQ’s Superior Water System rating has a wide variety of requirements including a record for providing water that complies with all water quality standards and maintains high quality facilities.

“We’ve worked very hard since acquiring the CTI and S&S water systems a few years ago, to ensure that the quality of their water was brought up to par with what San Antonians expect,” said SAWS Director of Resource Quality, Veronica Godley. “We’ve made improvements in the physical system, as well as the process by which the water is tested and treated.”
