The two diagrams below give information about the different methods of collecting water for irrigation purposes.
The first diagram is using swing basket method to fetch water from the soil. The material needed are the basket made from bamboo, the digging soil extracted up to 2 meters near the irrigation channels, four meters ropes which will be used as much as two meters for each side. To begin, the ropes should be tied to each side of bamboo basket which is will be put to the hole of digging soil. After that, the bamboo basket that has been filled by the water can slowly lifted by pulling the ropes. Finally, the irrigation channels can be filled by water using this method until it's full.
The second diagram is utilizing the roller bucket to reap water for irrigation purposes. The material needed are the plastic bucket, a 50 meters stagnant pit near the irrigation tunnels, a pulley, two rollers, and a cow standing at downhill. Firstly, the rope is needed to be tied to the each roller and the bucket handle. The pulley is plugged to the ground near the irrigation tunnels while the other side of the rope that has been bound to the basket handle is wound to the cow body. At the end of this method, the bucket should be entered the stagnant pit and the cow might be pulled the rope until the basket reach the top of the stagnant pit. The full of water bucket will be automatically filled the irrigation tunnels as the pulley plugged near the irrigation tunnels.
Overall, both of the diagrams explain the way to collect water for irrigation purposes. However, the second method is more effective and efficient to be practiced eventough the materials of it is more complicated.
