I don't think it's quite the same thing. And what is urine, after all? Take the water out of it and what do you have left, and in what quantity? Measure out those components in dry form, sprinkle them in a multi-million gallon reservoir and nobody would get worked up, so long as they didn't know they originated with urine. Urine is looked upon as disgusting, and people react emotively to the idea of consuming it, even in amounts so small as to be nonexistent. It's very much like the "pink slime" scandal, which pretty much shut down a viable industry.
