Central Arizona Irrigation & Drainage District

Central Arizona Irrigation & Drainage District (CAIDD) was formed in 1996 and is located in and around Eloy, Arizona. CAIDD is composed of 87,586 acres. CAIDD’s water is supplied by district operational wells and the Central Arizona Project (CAP). In 1990, CAIDD took over operation and maintenance of privately owned wells by 40-year leases. As a result of the operation of groundwater wells, water co-mingling has been available since 1987. 

There are five power suppliers whose service areas all fall within this District.  These are Electrical Districts, 2, 4, and 5 as well as the San Carlos Irrigation Project and Arizona Public Service.  CAIDD has approximately 223 miles of lined canals with 246 deliveries. Out of the district’s 27 mains and lateral canals; 12 are fully automated.

Annual water use for 2006 was 235,376 AF, in 2007 rose to 276,756 AF, and through April of 2008 water use has been 93,553 AF which is ahead of schedule in comparison to the previous years.
