Drain a drinking water reservoir because someone peed in it?

It's all been pee at some point or another (or at least a lot of it has)

Actually, a very very small amount, unless you count Dino pee.

It counts, because it was still pee. :)

Also, that doesn't cover all pee from all animals from the first pee of the first thing to have a bladder till now.

True, but due to time present, pee volume per animal, the dinosaurs really make up the bulk of the total.  The biomass pre-Dino was relatively small in comparison, and post Dino was a relatively limited timeframe.  Remember, there is as much time between a T.rex and a stegosaur as there is from a T.rex to now.

But yes, w.r.t. Drinking water that was once pee, if Dino pee counts, then, yes.

Theory says H2O was extra terrestrial, so we're drinking pee of space aliens!
