Aquifer storage and recovery (commonly referred to as ASR) is the practice of storing water in a suitable aquifer through a well when water is available and recovering the water from the same aquifer when it is needed. Typically, the same well is used for both injection and recovery.Some people refer to it as a “water savings account”.A well in such an aquifer is called an artesian well. The water in these wells rises higher than the top of the aquifer because of confining pressure. If the water level rises above the ground surface a flowing artesian well occurs. The piezometric surface is the level to which the water in an artesian aquifer will rise. The Puget Sound aquifer system is used extensively for ground-water supplies. Unconsolidated-deposit aquifers predominate.Jun 6, 2018 · Generally, the upper layer of an aquifer system is the unconfined aquifer, which does not have a confining layer of solid material above it.
