Water Science School Home
The water in the Nation's rivers, lakes, reservoirs, and underground aquifers are vitally important to our everyday life. These water bodies supply the water to serve the needs of every human and for the world's ecological systems, too. Here in the United States, every 5 years the U.S. Geological Survey (USGS) compiles county, state, and National water withdrawal and use data for a number of water-use categories.

Total Water Use in the United States
Sources/Usage: Public Domain. View Media Details
Water use in the United States in 2015 was estimated to be about 322 billion gallons per day (Bgal/d), which was 9 percent less than in 2010. The 2015 estimates put total withdrawals at the lowest level since before 1970, following the same overall trend of decreasing total withdrawals observed from 2005 to 2010. Freshwater withdrawals were 281 Bgal/d, or 87 percent of total withdrawals, and saline-water withdrawals were 41.0 Bgal/d, or 13 percent of total withdrawals. Fresh surface-water withdrawals (198 Bgal/d) were 14 percent less than in 2010, and fresh groundwater withdrawals (82.3 Bgal/day) were about 8 percent greater than in 2010. Saline surface-water withdrawals were 38.6 Bgal/d, or 14 percent less than in 2010. Total saline groundwater withdrawals in 2015 were 2.34 Bgal/d, mostly for mining use.

Total water use, by category of use, 2015
- Thermoelectric power and irrigation remained the two largest uses of water in 2015, and total withdrawals decreased for thermoelectric power but increased for irrigation.
- Withdrawals for thermoelectric power were 133 Bgal/d in 2015 and represented the lowest levels since before 1970.
- Irrigation withdrawals were 118 Bgal/d in 2015, an increase of 2 percent from 2010 (116 Bgal/d), but were approximately equal to withdrawals estimated in the 1960s.
- Public-supply withdrawals in 2015 were 39.0 Bgal/d, or 7 percent less than in 2010, continuing the declines observed from 2005 to 2010.
- Self-supplied industrial withdrawals were 14.8 Bgal/d in 2015, a 9 percent decline from 2010, continuing the downward trend since the peak of 47 Bgal/d in 1970.
- Total aquaculture withdrawals were 7.55 Bgal/d in 2015, or 16 percent less than in 2010, and surface water was the primary source (79 percent).
- Total mining withdrawals in 2015 were 4.00 Bgal/d, or about 1 percent of total withdrawals from all uses and 2 percent of total withdrawals from all uses, excluding thermoelectric.
- Livestock withdrawals in 2015 were 2.00 Bgal/d, the same as in 2010.

Total water withdrawals, by State, 2015
In 2015, more than 50 percent of the total withdrawals in the United States were accounted for by 12 States (California, Texas, Idaho, Florida, Arkansas, New York, Illinois, Colorado, North Carolina, Michigan, Montana, and Nebraska). California accounted for almost 9 percent of the total withdrawals and 9 percent of freshwater withdrawals in the United States, predominantly for irrigation. Texas accounted for almost 7 percent of total withdrawals, predominantly for thermoelectric power, irrigation, and public supply. Florida accounted for 23 percent of the total saline-water withdrawals in the United States, mostly from surface-water sources for thermoelectric power. Texas and California accounted for 59 percent of the total saline groundwater withdrawals in the United States, mostly for mining.

Water Use Information by Topic
Water is everywhere, which is fortunate for all of humanity, as water is essential for life. Even though water is not always available in the needed quantity and quality for all people everywhere, people have learned to get and use water for all of their water needs, from drinking, cleaning, irrigating crops, producing electricity, and for just having fun.

Trends in Water Use in the United States, 1950 to 2015
How has America's water use changed over the last 65 years? Are we using more or less water, and are there trends for different kinds of water use?
Surface Water Use in the United States
The Nation's surface-water resources—the water in the nation's rivers, streams, creeks, lakes, and reservoirs—are vitally important to our everyday life.
Thermoelectric Power Water Use
Much of the electricity used in the United States and worldwide comes from thermoelectric power plants. This type of production includes fuels such as coal, oil, gas-fired, nuclear, and other lesser-used methods, such as geothermal and burning waste material. Production of electrical power results in one of the largest uses of water in the United States and worldwide. Water for thermoelectric...
Groundwater Use in the United States
Groundwater is one of our most valuable resource—even though you probably never see it or even realize it is there. Groundwater is essential for irrigation and human use in many parts of the country. The use of groundwater in the United States in 2015 is described below.
Saline Water Use in the United States
Do you wear contact lenses? If so, you most likely use a saline water solution to clean them. But what else do we use saline water for and do we really use that much? Read on to learn all about the use of saline water.
Freshwater Withdrawals in the United States
The freshwater in the Nation's rivers, streams, creeks, lakes, reservoirs, and in underground aquifers are vitally important to our everyday life, and, indeed, to all life on Earth.
Public Supply Water Use
It is likely the water you use at home is brought to you by a public water-supply system. These are agencies, such as your local county government, that find and get the water that is delivered to not only your home, but to many businesses and industries. Most of the population of the United States gets their water this way.
Irrigation Water Use
Throughout the world, irrigation (water for agriculture, or growing crops) is probably the most important use of water (except for drinking and washing a smelly dog, perhaps). Irrigation water is essential for keeping fruits, vegetables, and grains growing to feed the world's population, and this has been a constant for thousands of years.
Livestock Water Use
Livestock water use is water associated with livestock watering, feedlots, dairy operations, and other on-farm needs.
Aquaculture Water Use
As the label in the grocery store says, " Farm Raised Tilapia Fillets " are for sale! Yes, aquaculture and fish farming are big businesses nowadays, and with the rising population of the world, more and more seafood will be grown in the future in aquatic farms.
Domestic Water Use
Domestic water use is water used for indoor and outdoor household purposes— all the things you do at home: drinking, preparing food, bathing, washing clothes and dishes, brushing your teeth, watering the garden, and even washing the dog. At the U.S. Geological Survey (USGS), domestic water use refers to the amount of water that is "self-supplied", or water withdrawn directly by users, such as from...
Industrial Water Use
The industries that produce metals, wood and paper products, chemicals, gasoline and oils, and those invaluable grabber utensils you use to get your ring (which also needed water to manufacture) out of the garbage disposal are major users of water.
