I do not agree, I think net water consumption comparing ball production and reservoir application is meaningless. At a minimum, the working life of the balls is very long, and their production could well be in an area where water availability is not an issue. Keep in mind that river water that is not utilized before treatment and discharge just ends up in the ocean without benefit. Increased evaporation when a reservoir is covered with balls does not seem to make thermodynamic sense. Using white balls would certainly alleviate that if it were true, which I doubt.
