Core Points - The Ministry of Water Resources has announced the implementation of 9 new water industry standards effective December 29, 2025 [1] Group 1: New Standards Overview - The new standards include the "In-situ Testing Procedures for Soil Permeability in Water Conservancy and Hydropower Engineering" series, which consists of three parts: 1. Drilling Water Pressure Test (SL/T 31.1—2025) 2. Water Injection Test (SL/T 31.2—2025) 3. Drilling Pumping Test (SL/T 31.3—2025) These standards aim to enhance the standardization and application of testing techniques in water conservancy projects [2] - The "Geological Observation Procedures for Water Conservancy and Hydropower Engineering" (SL/T 245—2025) has been revised to include 9 chapters and 3 appendices, focusing on various geological observations relevant to water conservancy projects [3] - The "Technical Specifications for Cemented Dams" (SL/T 678—2025) consolidates previous guidelines and includes 8 chapters and 3 appendices, aimed at standardizing the construction techniques for cemented dams [3] Group 2: Additional Standards - The "Exploration Procedures for Water Conservancy and Hydropower Engineering" (Part 3: Pit Exploration, SL/T 291.3—2025) has been revised to improve the quality and safety of pit exploration work in water conservancy projects [4] - The "Design Guidelines for Fish Passages in Water Conservancy and Hydropower Engineering" (SL/T 609—2025) aims to standardize the design of fish passages, ensuring quality and effectiveness in fish migration [4] - New standards for measuring microplastics in surface water (SL/T 849—2025) and for dynamic evaluation of groundwater (SL/T 850—2025) have been established to enhance monitoring and management of water quality [5]

Core Viewpoint - The Ministry of Water Resources has approved the release of nine industry standards related to water conservancy and hydropower engineering, which will take effect on December 29, 2025 [1] Group 1: Industry Standards - The announcement includes the approval of the "In-situ Permeability Test Procedures for Water Conservancy and Hydropower Engineering Part 1: Borehole Water Pressure Test" among other standards [1] - A total of nine standards have been approved for implementation, indicating a regulatory update in the water conservancy sector [1]

Group 1: New Standards Released - The Ministry of Water Resources has approved six new industry standards, effective from August 12, 2025, including the "Quality Acceptance Standards for Safety Monitoring Engineering in Water Conservancy and Hydropower Projects" [1] - The "Quality Acceptance Standards for Safety Monitoring Engineering" includes 10 chapters and 2 appendices, focusing on unit engineering division principles, quality acceptance organization, and safety monitoring quality inspection requirements [1] - The "Rock Sonic Parameter Testing Instrument Calibration Method" has been revised to standardize the calibration process for rock sonic parameter testing equipment, aiding in the lifecycle management of water conservancy projects [2] Group 2: Design and Safety Standards - The "Design Specifications for Reinforcement of Earth-Rock Dams" aims to enhance the quality of dam reinforcement designs, ensuring the safety of earth-rock dam projects [2] - The "Guidelines for Identifying Major Accident Hazards in Water Conservancy and Hydropower Projects" provides a framework for identifying significant safety risks during construction and operation, supporting risk management mechanisms [3] - The "Guidelines for Hazard Identification and Risk Assessment in Water Conservancy and Hydropower Projects" will standardize the process of hazard identification and risk evaluation, promoting safety in water conservancy operations [3] Group 3: Water Resource Management - The "Technical Guidelines for Water Resource Scheduling in River Basins" outlines the technical requirements for developing water resource scheduling plans, enhancing management practices in river basin water resource allocation [4]
