Almost no matter how you do it, it’s going to be a horrible waste of good drinking water to try to extract cooling from the temperature of the water. If you are in a dry climate, make a DIY swamp cooler. Otherwise shell out for a small AC unit.
Also; using your free lease-included water for stuff like that, is probably the quickest way to no longer have water included in your lease…
WTF is going on with the routing of those two aqueducts?..
