Aquifer Storage and Recovery
A cost-effective and efficient way to manage the available water supply
 ASR – Meeting Tomorrow’s Demand for Water Today
As increasing stress is put on our natural water supply, alternative sources of water and new methods of conservation and reuse are continually being sought by public and private interests alike. One promising alternative is aquifer storage and recovery (ASR).
ASR is a proven technique for storing water in an underground aquifer during times when excess water is available, and recovering that water at a later date when it is needed. This technique is being widely recognized as:
- A cost-effective and efficient way to manage the available water supply, and
- A means of developing alternative water supplies that have been, to date, unavailable because of storage limitations.
Thus far, ASR has primarily been used for storage and recovery of potable water. Recently, however, its applications have been extended to reclaimed water, treated surface water, and raw surface and groundwater.
 ASR Applications and Benefits
As a water resource management tool, ASR offers users an impressive range of applications. For example, ASR systems – when used as salinity barriers – can be used to minimize saltwater intrusion and enhance overall performance in water wellfields. Additionally, ASR can be used to augment aquifer water levels and restore them to target elevations, simply by leaving a small portion of stored water in the aquifer each time some is withdrawn. As ASR system implementation becomes more accepted nationwide, the benefits associated with it are becoming more widely recognized. ASR:
- Maximizes surface water supplies.
- Offsets groundwater use.
- Maximizes reuse opportunities.
- Provides a drought-resistant water supply source.
- Defers the need for water treatment facility expansions.
- Provides a cost-effective and unlimited means of storage.
- Provides an underground source of water for use during emergency situations.
