The rope and bucket system is a commonly used animal-operated device for lifting water from wells deeper than 20 meters. In this method, a bucket attached to a rope is lowered into the well and then pulled up by animal power, usually oxen, making it efficient for greater depths.
It is widely used for domestic water needs and small-scale irrigation.
Animals like bullocks walk away from the well, pulling the rope and lifting the bucket filled with water.
This method allows control over the amount of water lifted and is suitable for deep wells.
Swing basket: Only suitable for shallow water lifting by manual labor.
Circulating two basket lift: A manual system used for shallow water.
