Rain Water Harvest System with First Flush Mechanism
Reported by Chip Kragt, Story written by Amanda MulderA Rain Water Harvest System was installed at the Anglican Church Rwintashya in Rwimpongo I Village. The tank has a volume of 10,000 liters and will store rain water to be used by more than 380 local residents.
This system is also the first system to test a "first flush" mechanism which will divert the first few minutes for rain from the tank, because these first few minutes of rain are the most likely to contain contaminents that can build up on the roof between rainstorms.
This mechanism was designed in partnership with the Calvin Water Institute in Grand Rapids, MI.

Solution:
We place these rainwater collection tanks at centrally-located churches, which shortens the walk for water and improves water quality. Churches sell the water at an affordable rate and use the income to maintain the system. Remaining funds are given to the poorest members of the community for school fees, health insurance, and other basic needs.
