The "Water Pollution Prevention and Control Plan for the Three Gorges Reservoir Area and Its Upstream Region (Revised Edition)" has recently been officially approved by the State Council and distributed to the Three Gorges Reservoir area as well as the upstream provinces of Hubei, Chongqing, Sichuan, Guizhou, and Yunnan. Following the revision, a total of 460 pollution prevention projects were identified, with an overall investment reaching 22.824 billion yuan.
The updated plan sets clear environmental goals, aiming for the water quality in key control sections of the Three Gorges Reservoir and its upstream areas to meet national standards for surface water environmental quality by 2010. It also targets a reduction in chemical oxygen demand (COD) emissions to 1.264 million tons, representing a 7.7% decrease from 2005 levels. To achieve these objectives, the plan outlines several critical measures.
First, it emphasizes stricter requirements for the construction and operation of sewage and waste treatment facilities. Second, industrial pollution will be more strictly controlled through structural adjustments, including the elimination of outdated companies and production capacities that do not comply with national industrial policies. The papermaking, chemical, brewing, and pharmaceutical industries will undergo optimization and cleaner production audits, while discharge permits will be issued based on total watershed control requirements.
Third, the plan strengthens regional protection strategies by implementing the State's division of major functional areas—such as optimized development, key development, restricted development, and prohibited development. This approach aims to balance economic growth with water quality protection across different regions.
Fourth, efforts to address ship-related pollution will be accelerated. Projects include the construction of ship waste receiving facilities, centralized treatment of domestic sewage, and chemical ship washing bases. Additionally, emergency response capabilities for ship pollution will be enhanced.
According to the revised plan, there are 131 urban sewage treatment projects expected to reduce COD by approximately 120,000 tons per year and ammonia nitrogen by around 14,000 tons annually, with a total investment of 8.361 billion yuan. Meanwhile, 243 industrial pollution control projects are planned to cut COD by about 100,000 tons per year and ammonia nitrogen by roughly 12,000 tons, requiring an investment of 6.15 billion yuan. These initiatives reflect a comprehensive and coordinated approach to protecting the ecological environment of the Three Gorges Reservoir and its surrounding areas.
