Aquifer storage and recovery

The first ASR well with a downhole control valve was installed in Highlands Ranch, Colorado, in 1992 for Centennial Water and Sanitation District.

[2] Doubts remain about the benefit of introducing ASR in such large capacity to Florida due to a predominantly karst geography.

[citation needed] During the injection process, electrical energy can be generated by the head pressure of the water flowing back into the aquifer.

[4] The Texan cities of El Paso, Kerrville and San Antonio use ASR, providing water resources to these water-vulnerable communities.

[5] In South Australia, the City of Salisbury in northern Adelaide has since 1994 played a pioneering role in establishing the viability of the capture and treatment of urban stormwater runoff within artificial wetlands, and injecting the treated water into Tertiary aquifers in winter, for later use by industry, and for irrigation of city parks and school playing fields in summer.
