Aquifer storage and recovery (ASR) is the direct injection of surface water supplies such as
ASR use in the United States
Colorado
The first ASR well with a downhole control valve was installed in
Florida
The use of ASR in Florida has been examined to determine potential benefits for the Everglades and other Floridian water systems under the Comprehensive Everglades Restoration Plan (CERP). An estimate of 333 ASR wells would be implemented as part of CERP and used to store, treat and supply excess surface water to the Everglades and other systems of water during dry periods. [2]
Controversy
Doubts remain about the benefit of introducing ASR in such large capacity to Florida due to a predominantly
Oregon
The first agriculture ASR wells were put into service in Oregon in the autumn of 2006 and have injected well over 3,000 acre-feet (3,700,000 m3) of water during the winter and spring flood flow times using artificial recharge (AR) of flood water as their water source. This shallow recharged water is then recovered as potable water and injected into the deep basalt aquifer.[citation needed]
During the injection process, electrical energy can be generated by the
Both of these well types use a down-hole control valve. ASR can also be used to re-inject water used by
Texas
The Texan cities of
San Antonio stores drinking water in its Carrizo ASR facility, which contains more than 91,000 acre-feet of water and has a maximum capacity of 120,000 acre-feet.[5]
A 2010 Texas Water Development Board (TWDB) survey of Texas water utilities found four primary objections to ASR in other parts of Texas: legal and physical limitations, the quality of the recovered water, cost-effectiveness and the potential for other pumpers to capture the utility's stored water.[5]

In South Australia, the

In Spain, the SubSol ASR project is active[10] and in the Netherlands, there is the COASTAR project.[11]
