Let’s think about how much water we use in a day. I think few of us try to do this. First, figure out roughly how much water you use in a day with this list.

*bathroom : 10liters each time
*bath : 200liters each time
*shower : men 80liters, women 96liters each time
*laundry : 70liters each time
*cooking : 60liters (including washing dishes) each time
*when you turn a tap : 12liter per minute


How much do you use?
Average Japanese people use 250 liters a day.
