This irrigation system in the Aravalli Hills near Udaipur is not a Rahat, but a Charas or Chades, which operates on a rope-pulley system. Oxen pull a rope up a ramp to hoist a large leather bag (the Charas) from a deep well. As soon as the bag reaches the top, it empties into the canal. There is no rotating wheel with many buckets here. – 1990
