I have a brother who lives in a beautiful part of the north island New Zealand.  They have a water shortage.  All his water comes from collected rainwater.
They have a saying:
 "If it's yellow, let it mellow.  If it's brown, flush it down."
  They live by that. 
If Londoners alone applied that rule, they could save over 6 billion gallons of water a year

He's not a window cleaner.
But that is their water source, bottled water for drinking, everything else from the rainwater, through a very primitive seive filter into the house plumbing.  So, it makes them careful about their usage.
Just pointing out how much is actually wasted!
