Usually a spade is used for making these channels. Channels are dug in the ground to regulate the flow of water. Wherever digging is difficult or has to pass through a village track route, underground channels covered with slates are constructed. Sometimes, in this situation, wooden channels are also constructed. The wooden channels are prepared by making a deep groove in a tree trunk.
Main channels are long and considerable labour is required for their annual maintenance and repair.
The whole community plays an important role in the construction of the main irrigation channels as well as in the equitable distribution of water. Usually the community works together for this purpose. Minor channels linked to the main channel irrigate all fields. The need for a second irrigation arises only after about three weeks. The process of irrigating a field is begun by flooding the nearest compartment, followed by the next, and so on.
