West Salt River Valley Basin Study

The West Salt River Valley Basin Study (WSRVBS) is a collaborative effort lead by the West Valley Water Association (WVWA; formerly WESTCAPS) and U.S. Bureau of Reclamation that began in July 2014. WVWA consists of West Valley municipal and private water providers, along with interested water agencies, that work to develop regional water solutions. The study area includes the western portion of the Phoenix metropolitan area, as well as the adjacent Lower Hassayampa, Rainbow Valley and Lake Pleasant groundwater sub-basins. As one of the fastest growing urban areas in the country, the projected rate and location of population growth are of principal concern. Municipal water demands in the region are expected to grow considerably. Additional renewable supplies must be secured in order to meet this demand without negatively impacting the aquifer system.

A final report for the Study is being drafted and is slated for release in August, 2021.
