Well BuLL (Gav_Chah) Well bull is a system to draw water from the ground to irrigate farms. Two liters of water per second are extracted from ground by the system. Two bulls are used for irrigation of 5000 meters agricultural land all day long. The remarkable thing is that the Bull is provided with a song, When a bull driver stops the song, cow moves and takes out water from well. History of this system is not available, but According to painted tiles of the Jame_Mosque of Isfahan (plays a yak in the Ramps is drawing water), its history dates back to before the Safavid era. After 50 years, the first well bull of Iran has been revived in Varzaneh.
