Aquifer Storage and Recovery (ASR)
Aquifer Storage and Recovery (ASR) is a water management technique where excess surface water, such as during rainy periods, is injected into underground aquifers—natural underground reservoirs—for later use. This process allows water to be stored safely underground and retrieved when needed, especially during dry periods or droughts. ASR helps optimize water supply, reduces reliance on surface reservoirs, and minimizes evaporation losses. It also improves water quality by filtering the water through natural underground layers, making it an efficient and sustainable way to manage water resources for communities and agriculture.
