The Japan International Cooperation Agency (JICA) Nepal handed over the rehabilitated Chandra Nahar Irrigation System under “The Project for the Rehabilitation of Irrigation System in Eastern Terai Area” at Bhagni Maleth in Saptari district.
The irrigation system was handed over in the presence of Sarita Dawadi, Secretary at the Ministry of Energy, Water Resources and Irrigation (MoEWRI); Yasuharu Shinto, Deputy Chief of Mission at the Embassy of Japan to Nepal; and Mizuki Matsuzaki, Chief Representative of JICA Nepal, according to a statement issued by JICA.
Completed in 1927, the Chandra Nahar Irrigation System is Nepal’s first modern irrigation system. The nearly century-old infrastructure has played a key role in supporting agricultural production and rural livelihoods in the eastern Terai but has faced deterioration due to aging structures and limited maintenance over the years.
Following a request from the Government of Nepal, JICA provided a Grant Aid of JPY 2.256 billion (approximately Rs 2.05 billion) for the rehabilitation of the system. The project involved the rehabilitation of 32 critical structures, including eight canal underpasses, nine cross-drainage works and 15 canal-crossing bridges.
According to JICA, the rehabilitated system has improved water distribution across 11,000 hectares of farmland and is expected to directly benefit around 35,000 farming households.
The project also carries historical significance rooted in early Nepal–Japan cooperation in engineering education. In 1902, eight Nepali students traveled to Japan for higher education, including Dilli Jung Thapa, Nepal’s first engineer, who later led the construction of the Chandra Nahar irrigation system.
“I would like to extend my sincere gratitude to the Government of Japan and JICA for their invaluable support, which has not only contributed to preserve this important historical infrastructure but has also ensured the successful rehabilitation of the irrigation system in line with modern engineering standards,” Dawadi said, adding, “In addition to the physical infrastructures, the support provided for human resource development—through knowledge and technology transfer, skill enhancement, and the promotion of a culture of constructing quality infrastructure—has greatly benefited the officials, this project and the surrounding communities.”
These contributions have made a significant impact on Nepal’s agriculture and irrigation sector, strengthening both its productivity and sustainability, Dawadi further said.
Matsuzaki in his remarks appreciated the cooperation and partnership of Government of Nepal, Ministry and other stakeholders to complete this historic project successfully and reaffirmed JICA’s commitment to working together with Nepal to support national priorities in agriculture, water resources that contribute to broader socio-economic development.
