The water consumed within a service area or no longer available as a source of supply; that part of a withdrawal that has been evaporated, transpired, incorporated into crops or products, consumed by man or livestock, or otherwise removed. For agriculture and wetlands, it is the Evapotranspiration of Applied Water (ETAW) (and Evapotranspiration (ET) of flooded wetlands) plus irrecoverable losses. For urban water use, it is the ETAW (water applied to landscaping or home gardens), sewage effluent that flows to a salt sink, and incidental ET losses. For instream use, it is the amount of dedicated flow that proceeds to a salt sink and is not available for reuse.
The withdrawal of water from a ground water source at a rate greater than its rate of recharge, usually over an extended period of several years.
The amount of water that flows into a valley, or onto a particular land area, minus the water that flows out of the valley or off from the particular land area.
That portion of the water supply that is consumptively used.
