Water Resource Availability for the Tucson, Arizona Metropolitan Area
Groundwater has long been a significant water source for many areas in Arizona.' In 1980 Arizona adopted the Groundwater Management Act (ACT) to address the serious groundwater overdraft that was occurring in Tucson and several other regions of the state by the municipal, industrial and agricultural sectors.' The Groundwater Management Act, through the goal of "safe-yield," has forced the municipal sector within the' Tucson Active Management Area (AMA) to utilize alternative, renewable sources of water.' This report focuses on the municipal sector of the Tucson AMA and explains how water management is accomplished and the manner in which municipal water providers - the suppliers of water to the Tucson region's residents and businesses - are likely to meet the future water demands of their service areas.
