Definition for

Beneficial use

Beneficial use is the legal basis for allowing all diversions of water from surface and groundwater supplies. Water that is removed from the state's rivers, streams and underground must serve a beneficial purpose to mankind, either economically, socially, recreationally, hygienically or other ways, or it is not granted a right. To allow water resources to benefit the greatest number of people, use of water must be reasonably efficient. A water right is a right to use the amount of water necessary to accomplish beneficial use without waste.
