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]
