South-to-North Water Diversion Equipment Completed Major Breakthroughs in Five Major Areas

After years of collaborative research, the South-North Water Diversion Project has achieved significant breakthroughs in five key areas. On August 14th, the Ministry of Water Resources and the China Machinery Industry Federation jointly held the "15th Five-Year Plan" national major technical equipment development plan — the Acceptance Meeting for the South-North Water Diversion Project Complete Equipment Development Project. Attendees included Soli Sang, Honorary Chairman of the Science and Technology Committee of the Ministry of Water Resources, Yan Yongbin, Deputy Secretary General of the China Federation of Machinery Industry, as well as experts from the Ministry of Water Resources Planning and Planning Department, the Ministry of Construction and Management, the South-to-North Water Transfer Project Planning and Design Bureau, and the China Institute of Water Resources and Hydropower Research. Zhai Yongbin emphasized that through this project, the focus was on water conservancy construction, leveraging national key projects to introduce, absorb, and innovate technologies, significantly improving the level of China's water conservancy equipment and narrowing the gap with advanced foreign standards. It also helped replace imported equipment and boost domestic capabilities. The national major technical equipment development plan is part of the country’s key scientific and technological breakthrough initiatives. The complete set of equipment for the South-North Water Diversion Project was jointly sponsored by the Ministry of Water Resources and the China Federation of Machinery Industry, marking the first major technical equipment development project undertaken by the water conservancy system. With strong support from relevant government departments, the water conservancy sector and equipment manufacturers worked together over three years to prepare and demonstrate the project. They partnered with international manufacturers for key technologies that were lacking domestically, using methods like prototype introduction to solve challenges. At the same time, they leveraged domestic technological strengths, encouraging enterprises to collaborate with research institutes and universities to enhance innovation. The project involved 5 topics, later adjusted to 22, with 49 participating institutions and a total investment of 208 million yuan. It resulted in 17 sets of independently developed equipment, 45 new products, and 22 patents, including two invention patents. Special attention was given to large-scale equipment needed for major water conservancy and hydropower projects. The project focused on five key areas: large low-lift pumps, channel construction, deep-buried tunnels, real-time water monitoring, and other critical technologies. Significant progress was made in each area. In the field of large low-lift hydraulic pumps, optimized design software was developed, and new performance prediction methods were introduced. Hydraulic model devices for various pump types were created and tested successfully. Monitoring systems were deployed in urban drainage and irrigation, enabling integrated information management. For large-scale channel construction, mechanized paving technologies and equipment were developed, along with construction techniques for aqueducts. These efforts improved China's overall construction standards. Deep-buried tunnel construction saw advancements in TBM technology, including improved geological forecasting tools and control systems. Key equipment such as high-lift hoists and concrete mixing buildings were developed and applied in the project. A water resource optimization management system was established, featuring real-time flow monitoring and automatic water quality monitoring systems. These innovations broke foreign technical monopolies and supported better water resource management. Experts at the meeting praised the project’s achievements, noting that it met its goals and laid a solid foundation for future developments in major water infrastructure. While China has made great strides in areas like dam design and sediment research, its equipment still lags behind. The South-North Water Diversion Project has significantly enhanced China's ability to develop and implement advanced water infrastructure solutions.
