Bucket systems may also be adapted to animal power to increase flow, such as with the [[Bucket_hoists,_Windlasses,_Mohtes_and_Water_Skips|''mohte'']], or self-emptying bucket. This traditional device employs either a tipping action or simple flap valves in the bucket or bag to discharge the water at lifts of 5-10 m (16-33 ft). The system can be arranged for the animal to walk back and forth in a straight line or in a circle, thus requiring less supervision.
