Aquifer storage and recovery (ASR) is a specific type of AR groundwater recharge practiced with the purpose of both augmenting ground water resources and recovering the water in the future for various uses.<small-title />

* More storage capacity needed to overcome seasonal dry periods and to reduce floods.<br>
