Aquifer Storage and Recovery Wells

Developing ASR Technology

GSWSA is a leader in the development of ASR technology.  This technology allows storing treated surface water in wells during off peak periods for use during emergencies or peak consumption conditions.  Currently 17 ASR wells are in operation or under development with a combined storage volume of nearly two (2) billion gallons.  Treated water can be withdrawn for use from ASR wells at a rate of 11 MGD or million gallons per day.
