Aquifer Storage & Recovery (ASR)
Underground reservoirs for storing treated water during surplus periods.
ASR systems inject treated surface water or reclaimed wastewater into aquifers when supply exceeds demand, then extract it during droughts or peak usage. This 'natural battery' for water reduces reliance on surface reservoirs, minimizes evaporation losses, and provides strategic reserves for climate-stressed regions.
