4. 4Engineers Without Borders - USA Assessment 2: July 2009 WORK: DISTRIBUTION WITHIN THE COMMUNITY FINDINGS: WATER NEEDS AND MAP OF DISTRIBUTION

5. 5Engineers Without Borders - USA Alternatives to Address the Need Current Sources: Natural Springs Improving Current System Repairing Existing Pipeline New Well Rainwater Harvesting System Reducing Dependence with Alternative Sources

6. 6Engineers Without Borders - USA Selection of School HOW? Elevated tank can be connected to our tank Reduce dependence on main line Reliable water source WHY? Ensure the Supply goes to the most vulnerable members of the village, the children. Example of rain water harvesting system that could be replicated around village Large Surface Area will yield appreciable amounts of rainwater. Possibility of expansion.
