I guess you could have very very efficient water cooling by using similar techinque that's used for both heating and cooling buildings here in Finland: earth-heating or whatever it's called. They drill a hole, like 200-400m deep to have a small pipe in. You run water in the pipe to ether gather heat or get rid of heat, depending on the situation (heating in the winter, cooling in the summer) I don't know the numbers for cooling, but for heating you get like 6kW heating-power for 1kW of electricity used to run the system. For cooling inside air for comfort, the cooling is practically 0 energy spenditure.
It costs around 15-20 k€ for a residential building here. Majority is labour cost including the drilling.
