In the United States, the highest water withdrawals are primarily attributed to three main sectors:
-
Agricultural Use: This sector typically accounts for the largest share of water withdrawals, mainly for irrigation. Agriculture can consume over 40% of total freshwater withdrawals in some areas.
-
Industrial Use: This includes water used for manufacturing, processing, and energy production. Industries such as power generation, mining, and manufacturing also make significant withdrawals.
-
Public Supply: This sector involves water withdrawn for distribution to households, businesses, and institutions. It includes water used for drinking, sanitation, and other domestic purposes.
Among these, irrigation in agriculture generally represents the largest portion of total water withdrawals across the country. However, the specific distribution can vary significantly by region based on climate, land use, and local policies.
