San Antonio Water System Brackish Groundwater Desalination Program
San Antonio, along with many parts of Texas is experiencing double digit growth rates every 10 years. San Antonio Water System (SAWS) must be able to provide adequate water supplies in order to meet this growth. SAWS, currently gets the majority of their drinking water from the Edwards Aquifer, but water levels are decreasing, resulting in limitati...
Everything is Bigger in Texas: Implementation of the Country?s Largest High Recovery Inland Brackish Groundwater Desalination Facility
This presentation provides insight on the San Antonio Water System (SAWS) project including facility planning and programming considerations, as well as a review of the proposed treatment process design. It includes information on the source water quality and proposed pretreatment and the unique approach proposed for the 3-stage RO treatment proce...
San Antonio Desal Moving Full Speed Ahead: Construction of the Saws Brackish Groundwater Desalination Facility
This paper presents the effort of the San Antonio Water System to meet their water supply needs. SAWS has implemented a Brackish Groundwater Desalination Program consisting of a reverse osmosis (RO) treatment facility utilizing groundwater from the Wilcox Aquifer and moving forward in the construction of a facility....
Capital Cost for Phased Expansions for Brackish Groundwater Desalination in Texas
This paper presents the capitol cost for a phased expansion for the San Antonio Water Systems ( SAWS) program to integrate 30 million gallons per day of desalinated brackish groundwater into their overall water supply strategy. The Brackish Groundwater Desalination (BGD) program is anticipated to be constructed in three phases. Phase one will del...
