Why is it a good idea to save water?

I've seen lots of people saying "Save water, it's good for the environment!" over the years. I've looked and looked and mostly ignored them (although was happy when the dropped 'turn the tap off when you're washing your hands - really not compatible with 'shower, not bath').

Water is a renewable resource, right? It goes through the sewer system, into the rivers or sea, evaporates and returns as rain. Or it goes through the sewer system and returns to our taps.

My region hasn't had a hosepipe ban since the 70s because of our good reserviors.

So why is it a good idea to save water? I've never actually managed to find an explanation, including now through google.

the water from your tap has had a huge amount of processing to make it fit to drink.. so letting it just run away is a waste to start with. (heck, washing with it is pretty wasteful as it's far far purer than that application requires).

and while, yes - water is sortof renewable .. globally, we're using more and more and more. the amount of water required to make is terrifyingly large, and aquifers all over are just going down and down because we use more than is filling them.
