The Arizona Department of Transportation, the Arizona Game & Fish Department and the Arizona State Parks Board are required to conduct a study every three years on watercraft fuel consumption and recreational watercraft usage. The fuel consumption data is collected to determine the allocation of motor vehicle fuel tax to the State Lake Improvement Fund. The information on recreational watercraft usage patterns on Arizona’s lakes and rivers is necessary, in part, to determine the distribution of SLIF funds to applicants.

The Water Infrastructure Finance Authority of Arizona is an independent agency of the state of Arizona established to finance the construction, rehabilitation, and improvement of drinking water, wastewater, wastewater reclamation, and other water quality projects. WIFA operates as a “bond bank” and has the authority to issue bonds on behalf of communities for basic water infrastructure.

The purpose of this report is to present the conceptual study results and recommendations for potable water and reclaimed water infrastructure requirements in the HAMP planning area. A second report has already been prepared with study results and recommendations for wastewater facilities. The projected land use assumptions and population projections used in this potable and reclaimed water conceptual plan are consistent with Pima County's Plan.
