Hosepipe bans are always around, they are not really the problem, it is when it goes further, standpipes on street corners and so on...if it gets to that level in whatever area you work then it may well be that you are going to have real problems!
I see nothing wrong with restricting water use with things like using a hosepipe to water the garden and washing cars.
A staggering amount of water can be used by very few people in a very short amount of time...
Having said that, it's the bloody water companies that are the real culprits where water wastage is concerned

Up to 40% of water is lost through leaks before it even reaches it's intended destination
Now that is staggering I think.
Back in 76 we had the worst drought in modern times, standpipes on corners etc etc.
You would have thought that the powers that be would have been taught a salutary lesson...
But what has happened since that time? Have the leaks been slowly coming under control?
Have they hell, they have increased year on year, more water is lost due to leaks than ever before, and they have the gall to lecture us (all of us, not just window cleaners) on wasting water.
It really makes my blood boil

Put their own houses in order and THEN they can lecture us, not before.
But of course all they really care about is the shareholders, profits and dividends and the potential to sell on the business at a huge profit
The rules on these utilities need to be changed, I don't know how, I just know they need changing....
