Always attach importance to save water

Hello,

I'm a student who is from China. You know many developing country have meet water shortage problem in cluding China. In spite of that, many people are lack of enough concious of protecting environment including saving water, I get idea to give people more and efficent remind of saving water. we can desigh a electronic system to settle in the family, the system connect to the tap water pipe which can record water's flow quantity and serious data about the water you've used by small digital screen(same like mang electronic screen), more importance, the system also can make voice to give some kinded reminds to tell people their water used conditions. I think frequence human's voice reminds will be much helpful to let people realize the improtance of save water and carry out save water
