During 1977, an average of 21,466 million gallons of water was withdrawn daily for use in Florida--an increase of 6,153 million gallons per day since 1970. The 1977 daily use was 14,812 million gallons of saline water and 6,654 million gallons of freshwater. Most of the saline water, largely surface water, was pumped from tidal estuaries. Only 107.6 million gallons per day of saline water--less than 1 percent--was obtained from wells. Thermoelectric power generation used virtually all the saline water, 14,738 million gallons per day, whereas all other industrial uses were only 73 million gallons of saline water per day. The freshwater supply was almost equally divided between ground water (53 percent) and surface water (47 percent). Of the total freshwater used, 43 percent was for irrigation--an average of 2,873 million gallons of freshwater daily on the average. The remaining daily use of freshwater was 21 percent for thermoelectric power generation, 19 percent for public supply; 14 percent for industrial use other than thermoelectric power generation; and 3 percent for domestic and rural use. Irrigation was also responsible for the greatest consumption during 1977, with 1,255 million gallons consumed daily which also includes 192 million gallons per day conveyance loss. (Kosco-USGS)
