Cooling can be done by simply digging down several feet,
and running smooth conduit in a serpentine fashion. One end
exits into the area you want to cool, and a simple fan, or a solar
chimney, forces warm air into one end of the conduit, and cool
air comes out the other end. No water is needed, or wanted.
Brief articles to get you started:

This works because the ground below a certain depth is usually
much cooler than the surface, which is why your grandparents
dug a root cellar to store vegetables and preserves.
You need to make sure it is well screened to keep "critters" and
pets out.
You could always drill a well and use a
subterranean aquafer for
heating/cooling.... :)
Interesting idea; its cooling you have to worry about most for a
machine room and I don't know if there's a way for me to get
sufficient cooling that way. (I live in a desert, my house is on clay
and I have no idea if there's any aquafer beneath me.) Some of these
ideas translate into "feasible, but not cost effective" compared to
traditional A/C.
