(b) a large wheel with earthen pots tied to the outer ends of its spokes
This refers to another irrigation device (like the moat/girba), not the Araghatta.
While bullocks may be used in some systems, this option does not describe the wheel-and-pot system of Araghatta specifically.
This describes a simple pulley system, but lacks the mechanical sophistication of Araghatta.
| Device | Description | Operation Method |
|---|---|---|
| Araghatta | Large vertical wheel with pots tied to spokes; rotates to lift water | Powered by animals or humans |
| Moat / Girba | Leather bag or bucket pulled over a pulley to lift water | Manual or animal-driven |
| Dhenkuli | Lever-based water lifting system (seesaw type) | Manual operation |
| Rahat | Persian wheel; similar to Araghatta but more widespread in medieval India | Animal-powered continuous lifting |
| Device Name | Mechanism / Description | Source of Power | Key Features | Usage Context |
|---|---|---|---|---|
| Araghatta | A large vertical wheel with earthen pots tied to its spokes; rotates to lift water from wells or rivers | Human or animal-powered | Efficient continuous rotation; mentioned in ancient Indian texts | Common in ancient India for well irrigation |
| Rahat (Persian Wheel) | A wheel with buckets, powered by animals walking in a circle | Animal-powered (typically bullocks) | Similar to Araghatta but more prevalent in medieval and Mughal India | Popular in North India during medieval times |
| Moat / Girba | Leather water bag drawn up over a pulley | Manual or animal-powered | Basic lifting system; widely used where simple infrastructure sufficed | Small-scale irrigation and domestic use |
| Dhenkuli | A lever-based device that uses a counterweight and a long pole to lift water | Manual (by hand/foot) | Seesaw-like mechanism; low-tech and low-cost | Widely used in eastern India, especially Bengal |
| Picottah | Vertical lifting device with a long pole and counterweight | Manual | Traditional tool in South India, especially Tamil Nadu | Small farms and individual use |
| Concept | Explanation |
|---|---|
| Traditional Irrigation | Systems used before the advent of modern pumps; relied on simple mechanical principles |
| Sustainable Water Use | These devices often used renewable energy sources (human/animal) and were eco-friendly |
| Regional Variations | Device type varied by geography—Picottah in Tamil Nadu, Dhenkuli in Bengal, Rahat in northern India |
