An irrigation chain: approx. 2,000 maize plants, 500 bean plants

Due to the sandy soil the farmers had to dig a well farther from the water tank. In order to fill the tank over that distance we installed a 200 liter drum near the pump which is connected by ground pipes to the 13,000 liter tank. As the drum fills, the pressure in the drum exceed the pressure in the tank, and water begins to flow into the tank.
The water pump can usually pump faster than the water transfers from the drum to the tank, which could lead to an overflowing tank. However, this does not present a problem under normal conditions because the farmers take short breaks while pumping, allowing the drum and tank to equalize.

Though they said they had some challenges at first, the irrigation process has not been difficult for them. They were excited to share with us their plans for expansion.
