End uses of water for households in the U.S. in gallons per household per day and percent of indoor use [1]. 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]
Swimming pool covers that reduce evaporation and can warm pool water to reduce water, energy and chemical costs. Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands. Smart water meters are also a promising technology for reducing household water usage.
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. [14] [15] 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).

Cacti are some of the low-water-consuming plants often used in xeriscaping.. Xeriscaping has the potential to reduce water usage and maintenance, improve biodiversity, lower pollution, as well as mitigate heat within urban areas; however, the effectiveness of this sustainable process has not been evaluated on a long-term large-scale basis.
Safe household water storage is a critical component of a Household Water Treatment and Safe Storage (HWTS) system being promoted by the World Health Organization (WHO) worldwide in areas that do not have piped drinking water. In these areas, it is not uncommon for drinking water to be stored in a pot, jar, crock or other container in the home.
Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...
Under the LCR, if tests show that the level of lead in drinking water is in the area of 15 ppb or higher, it is advisable—especially if there are young children in the home—to replace old pipes, to filter water, or to use bottled water. EPA estimates that more than 40 million U.S. residents use water "that can contain lead in excess of 15 ppb".
