Xinhua News Agency, Beijing, February 3rd. The water transfer during the South-to-North Water Diversion Project is currently in a critical period. The Ministry of Water Resources and China South-to-North Water Diversion Group have strengthened forecasting, patrol and defense, and emergency preparation to ensure the safety of water transfer projects, water supply and water quality during the ice age.

The reporter learned from China South-to-North Water Diversion Group that the ice-period water transfer period of the first phase of the South-to-North Water Diversion Middle Line from 2024 to 2025 will be from December 1, 2024 to February 28, 2025, and the involved canal sections will be exported from the Anyang River to the Beijuma River cryptor import canal section; the ice-period water transfer period of the East Line Phase I project will be from December 21, 2024 to February 28, 2025, and the involved canal sections will be mainly in the Jiaodong section east of Dongping Lake and the northern section north of the Yellow River.

The South-to-North Water Diversion Project is the largest water diversion project in the world. The first phase of the East and Central Line has transferred nearly 78 billion cubic meters of water to the north. Due to the increase in extreme weather, long-distance water transfer and large temperature gradient changes in recent years, the water transfer during the project is more complex and has many risks and hidden dangers.

The first phase of the South-to-North Water Diversion Middle Line Project provides nearly 114 million people along the route to provide stable and high-quality water sources for nearly 114 million people in the four provinces and cities of Beijing, Tianjin, Hebei and Henan. A relevant person in charge of the China South-to-North Water Diversion Group Central Line Company said that the mid-line ice age water supply is forecasted and predicted, and patrol and defense are carried out for key projects. At the same time, make dynamic dispatching, facility maintenance and emergency preparations, make every effort to ensure the water supply needs of the ice age, and ensure the effective operation of anti-icing equipment.

According to the 2024-2025 water transfer, the Zhong Line Company has promoted the application and construction of the digital twin ice age water transfer business, and added 20 sets of meteorological water temperature monitoring and sensing equipment to the northern section of the Anyang River inverted Siphon to realize real-time monitoring of meteorological water temperature. At the same time, the water transfer scheduling procedures for the ice age were optimized and adjusted to improve the efficiency and efficiency of water transfer during the ice age.

A relevant person in charge of the East Line Company of China South-to-North Water Diversion Group said that the East Line Project strengthens forecasting and early warning, uses digital twins and other technical means to collect and organize project meteorological and ice observation data, strengthen analysis and judgment, and ensure the safety of water transfer during the ice age.
