In the United States, a USGS nationwide compilation of public supply withdrawals and deliveries indicates that in 2010 the total daily volume of nonresidential use was approximately 12,000 million gallons per day (mgd) and accounted for about 29 percent of public supply withdrawals (or 45 gallons per capita per day when divided by the estimated ...
Water Usage Effectiveness (WUE) is a sustainability metric created by The Green Grid in 2011 to attempt to measure the amount of water used by datacenters to cool their IT assets. [1] [2] To calculate simple WUE, a data center manager divides the annual site water usage in liters by the IT equipment energy usage in kilowatt hours (Kwh).
Water metering is the practice of measuring water use. Water meters measure the volume of water used by residential and commercial building units that are supplied with water by a public water supply system. They are also used to determine flow through a particular portion of the system. In most of the world water meters are calibrated in cubic ...

A water footprint shows the extent of water use in relation to consumption by people. [ 1 ] The water footprint of an individual, community, or business is defined as the total volume of fresh water used to produce the goods and services consumed by the individual or community or produced by the business. Water use is measured in water volume ...
The recommended daily amount of drinking water for humans varies. [ 1] It depends on activity, age, health, and environment. In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for ...
Residential water use (also called domestic use, household use, or tap water use) includes all indoor and outdoor uses of drinking quality water at single-family and multifamily dwellings. [ 2] These uses include a number of defined purposes (or water end uses) such as flushing toilets, washing clothes and dishes, showering and bathing ...
Water balance in a basin. A general water balance equation is: [ 5] P = Q + ET + ΔS. where. P is precipitation. Q is streamflow. ET is evapotranspiration. ΔS is the change in storage (in soil or the bedrock / groundwater) This equation uses the principles of conservation of mass in a closed system, whereby any water entering a system (via ...
