That's a bunch of nonsense. If you calculated the water used in the production of every liter of drinking water, you would also find there are inefficiencies. It is the nature of adding value, you use more lower grade resources to produce higher grade resources. I know some of you will get an aneurysm just by reading that because you have an instinct level reaction to soft drink being described as value added, but reality simply is that a higher caloric drink that sells for higher monetary value is a higher value product than simple water. You could just as well publish a finding that you should filter your own pond scum and boil it yourself because the potable water infrastructure costs water to produce potable water you just squander by showering yourself.
