1970年对美国用水量的估计表明，平均每天约有3700桶水（每天十亿加仑）或人均每天约1800加仑的水被提取用于四种主要的渠道外用途：公共供应（用于家庭、商业和工业用途）；农村（家庭和牲畜）；灌溉;及自备工业（含热电）。1970年，这些用途的提取量比1965年估计的310桶/天高出19%。从主要水源抽取的水估计表明，68 bgd来自淡水地下水，1 bgd来自咸水地下水，250 bgd来自淡水地表水，53 bgd来自咸水地表水，0.5 bgd来自再生污水。
Estimates of water use in the United States in 1970 indicate that an average of about 370 bgd (billion gallons per day) or about 1,800 gallons per capita per day was withdrawn for the four principal off-channel uses which are: public-supply (for domestic, commercial, and industrial uses); rural (domestic and livestock); irrigation; and self-supplied industrial (including thermoelectric power). In 1970, withdrawals for these uses exceeded by 19 percent the 310 bgd estimated for 1965. Estimates of water withdrawn from the principal sources indicated that 68 bgd came from fresh groundwater, 1 bgd came from saline groundwater, 250 bgd came from fresh surface water, 53 bfd came from saline surface water, and 0.5 bgd was reclaimed sewage.
