The U.S. Geological Survey (USGS) reports analyzed water-use data for the United States every 5 years.
In 2015, domestic water use totaled 26,560 million gallons per day (Mgal/d), of which 88% was publicly supplied and 12% self-supplied.1 The total amount of water withdrawn in the United States in 2015 for all categories was 322,000 Mgal/d.1 Domestic water use therefore accounted for 8% of total U.S. water withdrawals in 2015.
