If they're using an open-loop system, then the water is being evaporated into the air, where it will eventually return as rainfall.Two things that I need to understand better... 1. Why do they need to use that much water? Can't they close the loop and recirculate the water? They can have a large enough reservoir of water so that it can cool mostly on its own. 2. What happens to the water after they are done with it. They aren't really doing anything to it to contaminate it are they?
One thing rarely pointed out in these articles is that the sites which use thse open-loop systems exist almost entirely in areas where water is cheap and plentiful. When water is scarce and thus expensive, normal economics forces them into closed-loop systems .. and an increasing number of them do such (I believe the latest figure is 75%+ of new sites under construction are closed-loop cooled.)
