I mean almost all: I keep few cubic feet in storage, in my body, and it will be given up some day.

Agricultural water use is typically misrepresented to the public. Say a unit of water is diverted to irrigation. Part of it is actually "consumed" by the plant itself, part is "transpired" or evaporated to the air. The largest part goes back to the ground - subsurface flow to the rivers and deep percolation to the aquifer.
