Existing SystemThe 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.
3 valves are used to alternate which portion of the village is receiving water. Each portion is open for 24 hours once every 3 days.

Proposed System with Existing System Interactions
Upon completion of the 3 distribution systems EWB-UMN will further investigate finding additional supply for the village. Currently, demand is greater than supply, increasing supply could then alleviate the problem of not having enough water to fill the entire pipe network to an extent where the pipes could build pressure.
Three day rotation system will remain until distribution implementations are complete.
