Why is it a good idea to save water?

[ghoti_mhic_uait]

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.

Our local water company have included lots of information recently about how low the aquifers are, and how if all their customers are careful with water they probably won't need to do a hosepipe ban, *if* last winter was rainy enough (I was busy with Charles, I didn't notice if it was).
