Main takeaway: 98% of the water I used was to deal with my waste (cleaning dishes, washing myself, toilet, etc). Only 2% was used for intake.
The 2% remains the same for the combined data of the entire class. However, some people included cooking water in the OTHER category, so the percentage of the intake amount may be higher.
The Home vs School comparison of each category reveals that despite the fact that we spend most of our waking hours in the studio, we still consume majority of the water at home.
