When will the introduction of Han Ji Wei be lifted in 2023?

Introducing Han into Wei in 2023 was released on July 16.

After more than ten years of construction, the major national water conservancy project, the project of diverting water from Han to Wei, was successfully put into water ahead of schedule on July 16, 2023, and was officially put into water in An. The river water drawn from the Hanjiang River, the largest tributary of the Yangtze River, will eventually replenish the Weihe River, the largest tributary of the Yellow River, after passing through the Qinling Tunnel for nearly 100 kilometers, thus realizing the "handshake" between the Yangtze River and the Yellow River in Guanzhong.

The project of diverting water from Han River to Wei River is one of the 172 major water conservancy projects determined by the State Council during the 13th Five-Year Plan period, which consists of water transfer project and water transmission and distribution project.

The project spans the Yangtze River and the Yellow River, and transfers water from the Hanjiang River Basin in Yangxian County in southern Shaanxi and Foping County in Hanzhong City to the Weihe River Basin in Guanzhong, which can meet the industrial water demand of four key cities such as xi, Xianyang, Weinan and Yangling, five new cities in Xixian New Area, Chang 'an District, Lintong District, Xingping City and Fuping County on both sides of Weihe River, and Weibei.

General situation of the project of diverting Han into Wei River

The total industrial water resources in Shaanxi are insufficient and unevenly distributed in time and space. Water shortage is a "bottleneck" factor that restricts the economic and social development of the province. Especially in Guanzhong and northern Shaanxi, the shortage of water resources has become a major problem that bears the brunt of economic and social development and environmental improvement at present and even in the future. The project of diverting water from Han River to Wei River is an important water resources allocation measure to solve this problem.

The project mainly consists of five parts: Sanhekou Reservoir and Qinling Tunnel, Huangjinxia-Sanhekou Water Transfer Project, Huangjinxia Water Source Pumping Station and Huangjinxia Reservoir Hub.

The dam site of Sanhekou Water Control Project is located 2 kilometers downstream of Sanhekou Village, Daheba Township, Foping County. Its main task is to store the Wuzi water in this basin and the water pumped into the main stream of the Han River by the pumping station.

The main dam type of barrage is roller compacted concrete gravity dam, with the maximum dam height of138.3m, the total storage capacity of 68 100 million m3, the regulated storage capacity of 550 million m3, and the normal storage level of 643m. The designed pumping flow of the pump station behind the dam is 50 m3/s, with the average pumping capacity of 900 million m3 for many years and the designed total lift of 95. 1 m. ..
