Tharu people are mainly involved in farming, thus irrigating fields is important. Tharus in western Nepal built canals that irrigate thousands of hectares of land. Hundreds of years ago, without using any sophisticated tools, they built hundreds of kilometers of irrigation canals in Nepal's Kailali and Bardiya districts. These canals are used by several villages. Its water and diversion works need to be managed fairly. For this purpose, the Badghars of different villages elect a person for the position of "Chaudhary" to manage a canal system. When needed, the "Chaudhary" orders the "Badghars" to send people to repair or build the canals. In most cases the Badghars and Chaudharis are unpaid leaders of the community. However, they are exempt from compulsory physical labor for the betterment of the society. As a token of respect, the community members may also help them in farming for a day free of cost.
