Wow, how do you use 42 ccf? My usage is for the two months is about 8 - 9 ccf. Family of 3. And I thought I was wasteful sometimes taking 2 showers on hot summer days. 

It has been estimated that the average American uses 30 times their global share of water. So I feel bad when I see my water bill, knowing that I use far more water than I need while people around the globe have barely any.
