>Russian government officials said many bizarre things in the past which never materialized.

some materialized, some haven't.

>This is one of them.

how would we know that? For example, nuclear powered cruise missile is beyond bizarre, yet they did it. Water transfer project is much more practical thing (and they already do have oil transfer pipelines, so why would they not do a water pipeline - if anything, unlike the oil, the water is a renewable resource), and there has been official interest on both sides, and adding your bizarrity indicator - we can conclude it is much probable thing to happen than the missile.

>If you still insist this thing is real, you should prove it with specific parameters of this project. Construction start, volume, length of pipe etc.

Where that info would come from? I pointed officially available facts. You have so far provided only blind statement "it wouldn't happen" and no facts to counter my facts.

As it happens simple Google has even more facts, including info you've been asking for:
