How does the water you flush down a toilet or the water you pour down the drain get cleaned safely before it's released into the environment? That's the work of a wastewater treatment plant. The San Antonio River Authority (SARA) began providing wastewater utility services in 1966. Today, SARA has four permitted active wastewater treatment plants. Let the San Antonio River Authority's Utilities team take you on an up-close-and-personal tour of the wastewater treatment process.
