Isn't this a tremendous waste of water?

  Pretty much. Fashioning your own air conditioning system is a neat way to learn about heat exchangers and condensers and all that, but nothing you make at home is going to be anywhere near as efficient as a modern air conditioning unit.

  It's only a waste of water if you assume the water is 'disappearing' afterward. In ontario water is mainly provided by lakes, then after treatment water is returned to the same lakes. The only waste is the power used to move/treat the water, but this is the equivalent of power used by the compressor/fan of a normal A/C anyway. The situation is obviously different if the water supply is not a closed loop, like in Australia where water is supplied from dams and then waste water in dumped into the ocean...

    Actually, I was thinking of my water bill...

  No more than conventional air conditioning is a waste of electricity. Use whichever is cheaper, ie less scarce.
