If we run out of water what happens then? Also, how is that possible?

of world's total water supply of 332.5 million cubic miles (about 1,385 million cubic kilometers) of water, on 96 percent saline. and, of total freshwater, on 68 percent locked in ice , glaciers. 30 percent of freshwater in ground. thus, rivers , lakes supply fresh surface water human uses constitute 22,300 cubic miles (93,100 cubic kilometers), 0.27 percent of total water, yet rivers source of of water people use.

not 'use up' water on earth. however, possible can use fresh drinkable water in specific area if waste it, pollute it, or if there drought.
possible, although economically costly, filter or evaporate sea water. being done in several places around world (e.g. saudi arabia gets drinking water way).
matter of supply , demand in specific geographical area.
