>saving water is not all that matters. actually, saving soap is a lot more important. the more concentrated the dirt and soap is in the water, the harder it is for the biological wastewater treatment to work. i can't find the reference but i remember reading an article in a german magazine lamenting about exactly that problem, suggesting that people don't use enough water instead of to much. That link would be worth its length in gold for me to show my spouse!
