SAWS Brackish Ground Water Desalination

San Antonio, Texas

The San Antonio Water System (SAWS) is developing a brackish groundwater desalination program in southern Bexar County.  Brackish groundwater is a plentiful, previously untapped local source of water that will help diversity San Antonio’s water supplies.  When complete, the desalination facility will deliver approximately 10 million gallons of water per day from the Wilcox Aquifer.  The plant is located at the existing SAWS Twin Oaks Aquifer Storage and Recovery site. 

Encotech provided Electrical Engineering services for the pre-design phase of the project.   The firms work included engineering services for 13 groundwater production wells and three injection wells.  Encotech also designed the electrical needs for the plants raw/brine/product conveyance systems and the reverse osmosis systems.

Presently, the project is in the design phases and Encotech is providing all electrical and instrumentation design for the production and injection well sites.
