According to media reports, in recent years, multiple cities along the Yangtze River have explored urban smart water management around the theme of ecological priority and green development, launched a battle for pipeline networks, transformed sewage treatment plants into resource factories, and innovated urban sewage treatment. The latest data from the Ministry of Ecology and Environment shows that the national control section of the main stream of the Yangtze River has reached Class II water quality for three consecutive years. The vivid practice of revitalizing the mother river of the Yangtze River provides important insights for strengthening water pollution control and water resource management. Water pollution control and water resource management are one and two sides, with the former being the foundation and the latter being the goal. The population and total economic output of the Yangtze River Economic Belt both exceed 40% of the country, and water pollution control in the Yangtze River Basin is closely related to the sustainable development of the Yangtze River Economic Belt. Over 40 years of governance, especially the systematic implementation since the 18th National Congress of the Communist Party of China, have led to a positive trend of continuous improvement in the water ecological environment of the Yangtze River Basin, and the effectiveness of water pollution control is increasingly evident. However, overall, there are still problems in China, such as a large base of pollution emissions, severe ecological damage, and insufficient capacity for ecological environment governance. Water pollution control is a long-lasting battle, and it is necessary to implement the development concept of innovation, coordination, green, openness, and sharing, and promote the iterative upgrading of water resource management. Adhere to integrated planning and enhance the systematic management of water resources. The fluidity of water resources determines their cross regional nature. Taking the Yangtze River Basin as an example, this region spans three major economic zones in eastern, central, and western China, covering 19 provinces, regions, and cities. As a shared resource, water resources require the cooperation of various entities within the basin to solve water environmental problems. In the past, the management model of "block by block" resulted in poor information flow, inconsistent standards, low efficiency in water pollution prevention and control, and difficulty in producing practical results. To enhance the systematization of water pollution control, it is necessary to develop a unified plan, clarify the rights and responsibilities of all parties, break through information barriers, and form collaborative capabilities under the guidance of top-level design, in order to optimize the allocation and unified scheduling of water resources in large rivers, lakes, oceans, and other water basins, and form a joint governance force. Enhance the scientific nature of water resource management through technological empowerment. According to media reports, there are cities that apply intelligent control systems to realize real-time dynamic monitoring and management of urban sewage data. The "water steward" can issue water transfer instructions when the water consumption increases, coordinate the regional sewage treatment capacity by estimating the drainage volume, and release the storage capacity in advance according to the prediction of the rapid rainfall generative model to avoid waterlogging. With the continuous evolution of information technologies such as 5G, the Internet of Things, and artificial intelligence, intelligent management has been continuously empowered, and the ability to dynamically, real-time, and scientifically mobilize water pollution control and water resource management has become precise and feasible. Through big data analysis and other means, it is possible to control the total amount of water use in river basins and regions, balance and coordinate the water demand of various regions and industries, unify the allocation of water resources, and integrate technology into water supply resource management. Deepen the integration of rigidity and softness, and improve the sustainability of water resource management. On the one hand, strengthening legal norms and enhancing rigid constraints. For example, the promulgation of China's first national river basin law, the "Yangtze River Protection Law of the People's Republic of China," provides legal guarantees for comprehensively strengthening the protection and restoration of the ecological environment in the Yangtze River basin. Only by drawing a bottom line with laws and regulations can we hold onto the red line. On the other hand, we need to leverage the market's "hematopoietic" function. The report shows that
