I wonder how much we all take water for granted. How surprised we`d be if we turned on a tap and nothing came out of it. It set me thinking... how much water do I use in a day, and how much of that do I waste by letting a tap run when I don`t really need to. I came across this. It turns out that we use 97 litres of water per day, under the average of 150 litres. It was an interesting exercise to do.
