portion of the village is
receiving water. Each
portion is open for 24
hours once every 3
days.

The system originally operated with
everyone having 24-hour availability.
The village then created a 3-day
rotation which improved the equity of
water distribution throughout the
village. In this proposal, we are
attempting to further improve the water
equity. Because we believe the idea
behind this behavior is so that the
active pipe fills 3-times faster and thus
increases water equity, we are going
to keep the 3-day rotation.
