03-14: San Antonio Water System's Cooling Tower Audit Program Results in Significant Water Savings

The San Antonio Water System's (SAWS) Cooling Tower Audit Program, designed to increase the water use efficiency in evaporative cooling towers, was initiated in 2000. To date, this program has resulted in significant water savings for both the cooling tower operators and the City of San Antonio, along with other major benefits which are outlined and discussed in this paper. The methodology used in this project is identified along with a case history.
