While the Edwards Aquifer will always be the cornerstone of San Antonio’s water supply, SAWS has already successfully developed several alternative sources, such as Canyon Lake, the Trinity Aquifer, and the Carrizo Aquifer. Our recycled water program provides highly treated wastewater to CPS Energy and other industrial customers who would otherwise use drinking water. And our underground Aquifer Storage & Recovery reservoir allows us to collect unused Edwards water during wet years to use in times of drought.

Funded by SAWS customers through the Water Supply Fee, these successful projects represent an investment of more than $600 million.
