2023 will be the golden year for China's water conservancy construction. The reporter learned from the Municipal Water Conservancy Bureau that the "Three-Year Action Plan for High-quality Water Conservancy Development in Chongqing (2023-2025)" (hereinafter referred to as the "Plan") was recently issued. According to the "Plan", in the next three years, the city will implement more than 1,800 water conservancy projects, with a planned total investment of more than 200 billion yuan and a completed investment of more than 120 billion yuan.

The implementation of the three-year action for the high-quality development of water conservancy in Chongqing aims to promote the establishment of a sustainable modern water conservancy project system and provide a strong water security guarantee for the construction of the Chengdu-Chongqing economic circle and the construction of a modernized new Chongqing. The relevant person in charge of the Municipal Water Conservancy Bureau introduced.

The "Plan" determined a series of small goals: by 2025, the compliance rate of river embankments above grade 5 in the city will increase to more than 88%, and the reservoirs and rivers with a drainage area of more than 200 square kilometers with flood control tasks will achieve full coverage of hydrological monitoring. The storage capacity will increase by 320 million cubic meters, the annual water supply capacity of water conservancy projects will increase by 210 million cubic meters, the penetration rate of tap water in rural areas will increase to over 91%, the effective utilization coefficient of farmland irrigation water will increase to 0.515, and the basic ecological flow rate of key rivers and lakes will not be lower than 90%, the water and soil conservation rate increased to over 72.2%, the dynamic adjustment mechanism of water price was preliminarily established, the city's urban and rural flood control capabilities were steadily improved, water supply security capabilities were significantly enhanced, and ecological security capabilities were significantly improved.

The goal is set, how to achieve it? The "Plan" clarifies the accelerated construction of a systematic and complete flood control and disaster reduction system, an intensive and efficient water resource allocation system, a powerful water conservancy system that guarantees people's livelihood, a healthy and sustainable river and lake ecosystem, a smart and smooth new infrastructure system, and an open and shared water conservancy service Six key tasks of the system.

The above six key tasks all have corresponding construction projects and planned investment. In terms of strengthening the construction of flood control and disaster reduction projects, the construction of the three flood control reservoirs of Tiaodeng, Zaodu, and Fushouyan will be promoted, and the comprehensive management of small and medium-sized rivers will be completed for more than 1,000 kilometers; in terms of promoting the construction of backbone water networks, the water resource allocation project in western Chongqing will be completed , promote the integration of Sichuan-Chongqing Northeast (Central Chongqing) and the substantive progress in the preliminary work of the South Chongqing Water Resources Allocation Project; in terms of promoting the construction of rural water networks, coordinate the construction of rural water networks and high-standard farmland transformation and upgrading demonstration projects in hilly and mountainous areas, Select 10 districts and counties with relatively good water source conditions, industrial layout, and project connection to start pilot projects for rural water network construction; promote comprehensive management of river basin ecology, create a number of water ecological civilization demonstration villages, green small hydropower demonstration power stations, and build a number of happy Rivers and lakes, create a number of national and municipal water conservancy scenic spots, etc.; speed up the digital transformation of water conservancy, promote the application of BIM construction management information system, promote the construction of digital twin river basins, carry out pilot trials of digital twin water conservancy projects, and promote the digital twin Three Gorges Project in Chongqing Regional construction, etc.; strengthen the construction of water conservancy science popularization carriers, promote water culture projects such as the Hydrological Museum and the Three Gorges Immigrant Memorial Hall (expansion), and the construction of a number of national and municipal water regime education centers, and build an exhibition hall for water resource allocation projects in Western Chongqing, etc. Keywords: infrastructure, infrastructure construction, domestic engineering news, planning investment
