Economic Analysis of Artificial Recharge and Recovery of Water In Butler Valley, Arizona

摘要

Costs per acre-foot of water artificially recharged and recovered are estimated in assessing the economic viability of conjunctive management of Butler Valley, Arizona and imported surface water delivered by the Central Arizona Project (CAP) aqueduct. Proposed artificial recharge methods include spreading basins, channel modification and recharge wells. Calculated recharge/recovery costs for selected plans range from $94 to $488, depending on discount rate, design period, and power rate. With the implementation of proper water-management strategies, preliminary results indicate that conjunctive management of Butler Valley and CAP water might offer potential benefits to municipalities, industry, and agriculture in Arizona.
