Water withdrawals in Tennessee in 1990 were estimated to average 9,210 million gallons per day (Mgal/d) for offstream uses--a 9-percent increase from the 1985 estimate. Average per capita water use for all offstream uses was 1,890 gallons per day. Public-supply with- drawals (712 Mgal/d) represented a 14-percent increase from 1985 withdrawals. Self-supplied withdrawals during 1990 changed since 1985 as follows: domestic (59 Mgal/d), 16-percent decrease; commercial (55 Mgal/d), 1,000-percent increase; industrial (882 Mgal/d), 590-percent increase; and thermoelectric (7,320 Mgal/d), 21-percent increase. Total surface-water with- drawals in 1990 averaged 8,760 Mgal/d, which represents a 9-percent increase since 1985. Total ground-water withdrawals averaged 451 Mgal/d, which represents a 2-percent increase since 1985. Ninety-seven percent of the water used (8,950 Mgal/d) was returned to streams.
