In all fairness the chart does say average consumption. I take this to be annual/12. You might be suprized how close you are to the goal with that in mind.
It is interesting to me how much my drinking water bills vary when I rent my home out. It can easily increase by over 100% from one guest to another. For some guests I wonder how they can use so little, others I am curious if they are filling up a water tanker.
