The release and implementation of this standard is an important measure to implement the requirements of the "Groundwater Management Regulations". It is the first technical standard in the field of domestic underground reservoir engineering planning and design, and plays an important role in standardizing and guiding the design of underground reservoir engineering and promoting the construction and development of underground reservoirs.

The "Environmental Protection Design Code for Water Conservancy and Hydropower Engineering" (SL/T 492-2025) was revised on the basis of the "Environmental Protection Design Code for Water Conservancy and Hydropower Engineering" (SL 492-2011), and contains 15 chapters and 1 appendix. The main contents of this standard include ecological flow guarantee, water environment protection, aquatic ecological protection, terrestrial ecological protection, landscape protection, atmospheric environmental protection, acoustic environmental protection, solid waste disposal, soil environmental protection, environmental protection, environmental protection, environmental risk prevention and emergency plans, environmental monitoring and management, environmental protection investment overview (estimation), etc., and are suitable for environmental protection design of large and medium-sized water conservancy and hydropower projects. The release and implementation of this standard will further effectively standardize the environmental protection design work of water conservancy and hydropower projects, and provide technical support for the ecological environment protection of water conservancy and hydropower projects and maintain the virtuous cycle of river and lake ecosystems.

The "Regulations on Quality Inspection and Inspection of Hydraulic Metal Structure Manufacturing and Installation" (SL/T 582-2025) was revised on the basis of the "General Rules for Quality Inspection of Hydraulic Metal Structure Manufacturing and Installation" (SL 582-2012), and contains 9 chapters and 3 appendices. The main contents of this standard include inspection and testing items and inspection methods, gate inspection and testing, pollution barrier inspection and testing, pressure steel pipe inspection and testing, opening and closing machine inspection and testing, pollution cleaning machine inspection and testing, etc. It is suitable for the manufacturing and installation quality inspection and testing of hydraulic metal structure equipment such as gates, pollution barriers, pressure steel pipes, opening and closing machines and pollution cleaning machines. The release and implementation of this standard will further standardize the overall requirements, inspection and testing items and inspection methods for the quality inspection of hydraulic metal structure manufacturing and installation, and ensure the manufacturing and installation quality of metal structure equipment in water conservancy and hydropower engineering.

The Technical Specifications for Anti-corrosion of Hydraulic Metal Structures (SL/T 105-2025) was revised on the basis of the "Anti-corrosion of Anti-corrosion of Hydraulic Metal Structures" (SL 105-2007), and contains 10 chapters and 10 appendices. The main contents of this standard include surface pretreatment, coating protection, metal thermal spraying and coating composite protection, ceramic composite coating protection, cathode protection, etc., and are suitable for anti-corrosion design, construction, inspection, acceptance and maintenance of metal structures in water conservancy and hydropower engineering. The release and implementation of this standard will further standardize the anti-corrosion design, construction and inspection of metal structures in water conservancy and hydropower engineering, promote the application of new anti-corrosion materials, new technologies, new methods and new processes, and improve the corrosion resistance quality and technical level of metal structures in water conservancy and hydropower engineering.

The Technical Specifications for Anchor Spray Support in Water Conservancy and Hydropower Engineering (SL/T 377-2025) was revised on the basis of the Technical Specifications for Anchor Spray Support in Water Conservancy and Hydropower Engineering (SL 377-2007), and contains 11 chapters and 11 appendices. The main contents of this standard include engineering investigation and construction geology, anchor spray support design, anchor rod construction, steel arch frame construction, spray concrete construction, joint support construction, anchor spray support construction monitoring, construction safety and industrial sanitation, quality inspection and acceptance, etc. It is suitable for anchor spray support design and construction of various underground cave rooms in water conservancy and hydropower projects, as well as support design and construction of slopes, foundation pits and other projects supported by anchor rods and hanging nets. The release and implementation of this standard has a guiding role in the design and construction of anchor spraying support projects for water conservancy and hydropower projects, and also provides important technical support for ensuring the construction quality of anchor spraying support projects.

The Acceptance Regulations for Water Conservancy and Hydropower Construction Projects (SL/T 223-2025) was revised based on the merger of the Acceptance Regulations for Water Conservancy and Hydropower Construction Projects (SL 223-2008) and the "Regulations for Water Conservancy and Hydropower Construction Projects" (SL 176-2007), and contains 9 chapters and 6 appendices. The main contents of this standard include project division, construction quality acceptance, contract project acceptance, stage acceptance, completion acceptance, project handover and legacy problem handling, etc., and are suitable for acceptance activities of large and medium-sized water conservancy and hydropower construction projects and Level 1, Level 2 and Level 3 embankment projects. The release and implementation of this standard plays an important role in optimizing the acceptance procedures, improving the acceptance rate of water conservancy projects, promoting the new quality productivity of water conservancy, and promoting the high-quality development of water conservancy.

"Technical Specifications for Hydraulic Tunnel Engineering for Full-section Rock Boring Machine" (SL/T 839-2025) is a newly formulated water conservancy industry standard, including 12 chapters and 4 appendices. The main contents of this standard include basic regulations, geological survey, tunnel layout and design, boring machine selection and technical requirements, construction organization design, boring machine construction, unfavorable geological conditions response measures, safety monitoring, boring information management system, boring machine construction safety, etc., and are suitable for hydraulic tunnels constructed by full-section rock boring machine method. The release and implementation of this standard is a powerful measure to promote and ensure the continuous construction of national water grid projects, and plays an important role in standardizing and strengthening the construction of hydraulic tunnel projects for full-section rock boring machine.
