What is Aquifer Storage & Recovery?

ASR may be defined as the storage of freshwater in a brackish-water aquifer through wells during wet periods for subsequent retrieval from these same wells during dry periods. The freshwater forms a bubble within the aquifer around the ASR well, and can be retrieved when needed. Where is the water stored? Click on the image for a full-sized version.

The Major Advantages of ASR include: • Minimal Land requirements (an acre or two per well) • Almost no evaporation or seepage losses (mixing losses instead) • Proven technology at Boynton Beach (up to 95% recovery) These advantages translate into significantly lower costs per gallon of water stored.
