Harquahala Valley Irrigation & Drainage District

Harquahala Valley Irrigation & Drainage District (HVIDD) was established in 1964 and incorporated in Arizona. HVIDD is governed by a five member board made up of local landowners and the District is managed and operated by a total workforce of six employees. It is comprised of 33,500 irrigable acres located within the Harquahala Irrigation Non-Expansion Area (INA), south of Interstate 10 in Tonopah, Arizona. The land within HVIDD is currently irrigated with both groundwater and Central Arizona Project(CAP) water. Similar to other CAP subcontractors, the District has entered into a contract with Central Arizona Water Conservation District (CAWCD) to provide the delivery of excess CAP water. In addition to CAP water, power is available through the Harquahala Valley Power District established in June of 1987.
