Why is recharge important for the Phoenix area?
Proactive recharge in the Phoenix area is important because natural replenishment is very slow due to low precipitation. Recharge water will replace water that has been pumped out of the aquifer over many years. Continued pumping of water from the aquifer combined with inadequate replenishment can result in declining water tables, increased pumping costs, land subsidence and potentially loss of storage capacity in the aquifer.
