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.
