Aquifer storage and recovery
direct injection of surface water supplies such as potable water, reclaimed water, or river water into an aquifer for later recovery and use
Aquifer storage and recovery (ASR) is the direct injection of surface water supplies such as potable water, reclaimed water (i.e. rainwater), or river water into an aquifer for later recovery and use. The injection and extraction is often done by means of a well. In areas where the rainwater cannot percolate the soil or where it is not capable of percolating it fast enough (i.e. urban areas) and where the rainwater is thus diverted to rivers, rainwater ASR could help to keep the rainwater within an area. ASR is used for municipal, industrial and agricultural purposes.
In the United States
Colorado
The first ASR well with a downhole control valve was installed in Highlands Ranch, Colorado, in 1992 for Centennial Water and Sanitation District. Since then, over 40 ASR wells have been installed for many different municipalities. These wells range in depths from 1,000 ft (300 m) to 3,000 ft (910 m) below ground surface, with injection rates commonly between 100 US gal (380 L; 83 imp gal) and 500 US gal (1,900 L; 420 imp gal) per minute (gpm) per well.
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).
The public source identifies “Aquifer storage and recovery” as direct injection of surface water supplies such as potable water, reclaimed water, or river water into an aquifer for later recovery and use.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Aquifer storage and recovery”, the useful work is to connect “direct injection of surface water supplies such as potable water, reclaimed water, or river water into an aquifer for later recovery and use” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Nov 3, 2025. The linked authority identifier is Q4117849. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1992.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
