Monday marked the beginning of a week-long greywater installation course at the Humanist Hall. The day was jokingly deemed "Laundry Day." No, not the day to throw dirty clothes in the wash. Rather, the goal was to create a basic and inexpensive system to carry excess water from your washing machine to a drum, then into your yard for irrigation.

Visualize for a moment your morning shower. The warm water runs gently and momentarily over you, then falls to the drain. It goes on its merry way to...well, to a place most of us rarely think about. It simply goes "away" after our brief contact with it. Similarly, think about that last load of laundry you did. How much water did it take to complete these mundane tasks and where did it go?
