"this presents something of a watershed in the ISS' history"

i see what you're doing there :)

Are you taking the piss? or are you just extracting the urine (as a nerd would say)

im sure the end result beats what is in most bottled water these days.

Why not direct the shuttle towards a passing asteroid to extract some water?

or is the adolescent bodily-function humour in these stories getting a touch old?

Oh god.

I seem to remember the Urine Processor Assembly was a much simpler device in Waterworld.

I wouldn't have wanted to be the first person to realise it wasn't working...

.. to purify the water? Using a semi permeable membrane that only lets through water molecules (already developed) and is Bob your mothers brother? Am I missing a trick here?
