Which sector uses the largest percentage of Arizona's available water?

The agricultural sector uses the largest percentage of Arizona's available water due to the state’s dependency on farming and ranching. Agriculture has historically been the primary sector driving water consumption in Arizona, largely because of the extensive irrigation needed for crop production in a naturally arid climate. The state's agricultural industry includes the cultivation of various crops, such as cotton, alfalfa, and vegetables, which require significant amounts of water for irrigation throughout the growing season.

While municipal and domestic uses are also significant, their water requirements are considerably less compared to the massive needs of agricultural irrigation. Similarly, the industrial sector's water usage, while growing, remains relatively lower in comparison to that of agriculture. This highlights the crucial role that farming plays in the economy and water management in Arizona, making it the dominant user of the state's water resources.
