“Artificial recharge (AR) and aquifer storage and recovery (ASR) are processes that convey water underground. These processes replenish ground water stored in aquifers for beneficial purposes. Although the terms are often used interchangeably, they are separate processes with distinct objectives.
• AR is used solely to replenish water in aquifers
• ASR is used to store water which is later recovered for reuse”
