Originally developed in Ancient Egypt, a drawing of such a device appears on a Sumerian seal of c.2000 BCE. Well sweeps are still used in many areas of Africa and Asia to draw water. Also called a “shadoof” or “shaduf”, they remain quite common in Hungary’s Great Plains, where they are known as “gémeskút” (literally, “ heron wells”) and are symbols of the region. In France, where sweeps were still widespread in the countryside in 1986, they are called “balancing wells”.
The bucket ( or skin bag or coated reed basket) can be made in many different styles, sometimes having an uneven base or a part at the top of the skin that can be untied. This allows the water to be immediately distributed rather than manually emptied. The short end carries a weight (clay, stone, or similar) which serves as the counterpoise of a lever. When used for irrigation, with an almost effortless swinging and lifting motion, the waterproof vessel is used to scoop up and carry water from one body of water (typically, a river or pond) to another. At the end of each movement, the water is emptied out into runnels that convey the water along irrigation ditches in the required direction. Well sweeps in New England were more common one hundred years ago or more and came to be replaced by pulleys and cranks and eventually by mechanical pumps.
The well sweep at Joy Farm has been repaired many times over the intervening years, most recently by the current owners, although they no longer use water from the well.
