We tested a new type of pump today at Chifuchambewa. The ram pump takes in a high volume of water from a small dam, and puts out a small volume at a higher elevation.
The output is continuous and uniform, which makes irrigation with the pump easy to plan. The farmer will get exactly the same amount of water every day. The output is low right now because of the height to which it pumps (almost 40'). Yet, it will still provide over 1,000 gallons daily.
