Core Viewpoint - The Ministry of Water Resources of China has approved the release of nine new industry standards for the water conservancy sector, which will take effect on December 29, 2025, aimed at enhancing the standardization and reliability of water conservancy and hydropower engineering practices [1]. Group 1: New Standards Overview - The new standards include the "In-situ Permeability Test Procedures for Water Conservancy and Hydropower Engineering" series, which consists of three parts: Borehole Water Pressure Test (SL/T 31.1—2025), Water Injection Test (SL/T 31.2—2025), and Borehole Pumping Test (SL/T 31.3—2025). These standards are revisions of previous regulations and aim to improve the accuracy and reliability of test data [2]. - The "Geological Observation Procedures for Water Conservancy and Hydropower Engineering" (SL/T 245—2025) has been revised to include nine chapters and three appendices, covering various geological observation aspects relevant to hydropower projects [3]. - The "Technical Specifications for Cemented Dams" (SL/T 678—2025) consolidates previous guidelines and includes eight chapters and three appendices, focusing on the design and safety monitoring of 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) is a revised standard that includes ten chapters and nine appendices, aimed at enhancing the quality of pit exploration work [4]. - The "Fishway Design Guidelines for Water Conservancy and Hydropower Engineering" (SL/T 609—2025) has been updated to ensure quality in fishway design, including aspects of hydraulic design and operational management [4]. - The "Determination of Microplastics in Surface Water by Micro-Raman Imaging Spectroscopy" (SL/T 849—2025) is a new standard that outlines procedures for sampling and analyzing microplastics in surface water, contributing to pollution control efforts [5]. - The "Dynamic Evaluation Technical Specifications for Groundwater" (SL/T 850—2025) is also a new standard that aims to modernize and refine groundwater management practices [5].
