This points to the overall conversation about how fresh water is valued. If the sliding scale for fresh water prices was more aggressive, this would change the design of cooling systems for industry and large buildings. It is straight forward to design air-cooled refrigeration systems... even for operation in very hot/desert environments. With this in mind, I think pricing water to make it more cost effective to use water cooling towers, rather than entirely air cooled systems, is very poor policy. The amount of water used to provide cooling for Las Vegas, for instance, is absolutely ridiculous.
