Water use - definition (JQ-IW) In contrast to water supply (i.e. is delivery of water to final users including abstraction for own final use), water use refers to water that is actually used by end users for a specific purpose within a territory, such as for domestic use, irrigation or industrial processing. Excludes returned water (19). 04.06.2016Water losses and water use in private households
