China's "Southern Water Tone Project" is positioned as a huge project in China's country to send water from the southern region of China to the northern region in order to eliminate chronic water shortages in northern China. The total amount of investment is said to be approximately 500 billion yuan (approximately 10 trillion yen), which is one of the largest construction projects in history. Three major canals, the "Higashi Line," "Chuo Line," and "Nishi Line," were constructed to carry water from the Changjiang River basin (more than 1000 km each) to the receiving water section centering on Beijing and Tianjin.
The east line route, in which EBARA was involved, was planned to send water from the vicinity of Yangzhou in Jiangsu Province to the north along the grand canal and the river in the same direction, crossing the river in the vicinity of Shandong, and finally to Tianjin by passing through the Yellow River in a three-dimensional manner. The Infrastructure Company delivered five large tubular pumps, each of which has an outer diameter of 3 meters, to two airplanes in various pumping stations on the Higashi Line route. Some pumps are required to have a moisture function during flooding, which requires flexibility and efficiency in the operation of the pumps. With the completion of all pumping stations over a period of about 10 years, the Nankai-Hokucho Line Project has made it possible to supply water to the north at all times. Mitigating water shortages in northern China, the vast land is moistening, leading to the stability and development of the region's lives as a source of water for dozens of cities.
