That being said, water isn't like electricity, land, or a given year's tax revenues. It exists in a cycle and can be reused. It can be piped in from a potable water source, and you could probably develop a cooling loop that would return it back to the civic supply in potable form.
Other than somebody not wanting to because "b-b-b-b-but what about the shareholders!?", why not build that loop, put its components into mass production, and let economies of scale start cutting the cost while having less impact upon local water districts?
