• Rahat: Cattle is connected to a wheel. When the cattle moves, it rotates the wheel that has buckets attached to it. This helps in drawing water from the well.
• Dhekli: A bucket and a rock is attached to a wooden beam at either ends. When the farmer immerses an empty bucket into the water, the bucket is pulled up due to the weight of the rock attached to the other end of a wooden beam.
• Chain pump: The farmer rotates a wheel that allows the buckets attached to a chain to collect water.
