not to sound mean here, but i think a lot of people who waste water have never had to live with a well in their lives. my parents have a well, and after we had lived there 4 years after mom and pop built the house the well went dry and they had to drill a new one. my pop was the official water monitor - and he actually would time our showers. i got used to cold showers then because there was no waiting for the water to warm up at homei can still throw down a 3 minute shower....
I think many people waste water because they just don't think of it as a finite thing - 3 minute cold showers is a bit extreme, I'd just be happy if they'd turn off the sprinklers when it's raining so hard my windshield wipers are on high!
