Water wheels always appear in the dry season along streams in the northwestern region. The simple bamboo water wheel is associated with the traditional farming methods of ethnic minority groups in mountainous areas.

Water wheels are installed by hand by rivers and streams, where the water stream is lower than the field surface. The whole wheel is made of bamboo, tied with some stones to add weight for the wheel to turn around, taking water through the pipes to pour into the higher fields.
