A bucket pump is a simple, manually operated water-lifting device commonly used to draw water from shallow wells, boreholes, or open water sources. It typically consists of a cylindrical container (the bucket), a rope or chain, guide rollers or a pulley system, and sometimes a frame or hand crank for easier operation. The bucket may include a check valve or flap at the bottom to help retain water during lifting. This type of pump is widely used in rural and low-resource settings because it is affordable, easy to construct, and does not require electricity or fuel.

In operation, the bucket is lowered into the water source using a rope or chain until it is fully submerged and filled with water. Once filled, the operator pulls the rope or turns the crank to lift the bucket to the surface. If a valve is fitted, it opens as the bucket sinks to allow water in and closes when lifting begins to prevent spillage. When the bucket reaches the top, the water is poured into a storage container or trough for use. The process is repeated as needed. Although simple and reliable, the bucket pump is labor-intensive and best suited for low-volume water needs.
