National Water-Use Data

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...

Irrigation is the controlled application of water for agricultural purposes through manmade systems to supply water requirements not satisfied by rainfall. Crop irrigation is vital throughout the world in order to provide the world's ever-growing populations with enough food. Many different irrigation methods are used worldwide, including

In drip irrigation (microirrigation), water is run through pipes (with holes in them) either buried or lying slightly above the ground next to the crops. Water slowly drips onto the crop roots and stems.

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...

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.

If you look at our U.S. Geological Survey (USGS) water-use data , you see it is presented in "million gallons per day" (Mgal/d). We will help you visualize how much a millions gallon is so you can better understand our water-use information.

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.

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 is water associated with livestock watering, feedlots, dairy operations, and other on-farm needs.

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.

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.
