• System already in place when we arrived at Muchebe
• 20,000 L storage capacity collecting only from 25% of roof
area
• 7,000 L of water storage space wasted with two empty
tanks
Spring 2014 EWB Design
• Additional 50,000 L of storage space
• Collecting from 100% of roof area
• Total of 70,000 L of water  2L/student/day
Theory vs. Reality
•
•
•
•
Rock in the way of original tank cluster design
4 tanks instead of 5, but connected smaller tanks too
Still collecting water from 100% of the roof area
67,000 L capacity for water storage
