Fine but why not pump it out onto some crops? Here I am paying to heat water for my house and pool -- I should move next door to Google and hook up to their drain pipe.
Basically they pump in cold water and pump hot water back out.
Cooling the water is expensive and ineffective on large scales.
Beyond that you have evaporative cooling which is used for large scale HVAC systems in this case the water simply evaporates away into the atmosphere.
