The shadoof consists of an upright frame on which is suspended a long pole or branch, at a distance of about one-fifth of its length from one end. At the long end of this pole hangs a bucket, skin bag, or bitumen -coated reed (plant)  basket , while the short end carries a weight (clay, stone, or similar) which serves as the counterpoise of a lever. When correctly balanced, the counterweight will support a half-filled bucket, so some effort is used to pull an empty bucket down to the water, but only the same effort is needed to lift a full bucket.
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.
The Shadoof was also used to pickup dead people out of the Nile river(in early days) when there was a war.
