Typically the water go to an evaporative cooling tower outside to reduce the heat. As with all evaporative cooling, you lose some of that to evaporation and that has to be replenished. Some data centers perform rain water collection from their large roofs and use that to offset. Some data centers take the waste water treatment plant output and use that. Some data centers use geothermal to reject the heat into the ground (more niche but gaining momentum). I would encourage people to go research the amount of water consumed by data centers (including the power generation to run them) vs golf courses and almond farms in the United States. Something tells me that if you do that it will be eye opening numbers.
