Arizona Well Costs
Phoenix metro AMA: Very deep wells required (400–1,200 feet) due to declining water tables, $40–$80/ft — total costs of $20,000–$60,000+ not unusual. Tucson AMA: Similar depth issues. Rural southeastern AZ (Cochise, Graham counties): 200–500 feet, $35–$65/ft. Northern AZ (Flagstaff area): Volcanic rock, 300–600 feet, $40–$70/ft.
Arizona Active Management Areas
Five AMAs cover the Phoenix, Tucson, Prescott, Pinal, and Santa Cruz basins. Within AMAs, strict water use rules apply. Exempt wells outside AMAs allow household use. Inside AMAs, new exempt wells face severe restrictions — many properties must rely on hauled water or CAP water. Check ADWR first before purchasing rural land expecting a private well.
