Explanation of water-use (withdrawal) categories
Public supply -- includes water withdrawn by public and private
suppliers and delivered to users for any purpose. A portion of public-supply
withdrawals (15%) goes to public uses such as firefighting or is lost during
transfer, but much of it is delivered for domestic (53%), commercial (19%),
industrial (11%), or thermoelectric power generation (less than 1%)
purposes. Withdrawals not publicly supplied are self-supplied by the user.
These self-supplied withdrawals are typically grouped into the remaining
categories: domestic, commercial, industrial, irrigation, livestock, mining,
and thermoelectric power generation. Commercial/Industrial -- includes commercial and industrial withdrawals. Includes water used for industrial purposes such as fabrication, processing, washing, chemical and allied products, paper and allied products, mining, and petroleum refining. Commercial withdrawals include water for motels, hotels, restaurants, office buildings, other commercial facilities, and institutions. Agricultural -- includes irrigation and livestock withdrawals. Irrigation withdrawals include artificial application of water on lands to assist in the growing of crops and pastures or to maintain vegetative growth in recreational lands such as parks and golf courses. Livestock withdrawals include water for livestock watering, feed lots, dairy operation, fish farming, and other on-farm needs. Mining -- includes water used for the extraction of minerals occurring naturally including solids, such as coal and ores; liquids, such as crude petroleum; and gases, such as natural gas. Also includes uses associated with quarrying, milling, and other preparations customarily done at the mine site or as part of a mining activity. Thermoelectric power -- includes water used in the process of the generation of thermoelectric power. |
