Trends in total water withdrawals by water-use category, 1950-2005. Figure examines 5 different water users: public, rural domestic, irrigation, thermoelectric and other, and total withdrawals. Rural domestic water withdraws have stayed fairly consistent around 10 billion gallons a day. Public supply has slowly increase from 20 billion to 45 billion. Other uses have decrease by about 10 billion to around 35 billion. Irrigation has increased from 1950-1980 but then decreased slightly until 2005 to around 110 billion. Thermoelectric power increased steeply from 1950-1980 and then leveled out around 170 billion. The total withdrawals trend similarly increases from 1950-1980 and then levels out around 400 billion gallons of water withdrawn per day.
