Southeast Asia Information Port News (www.dnyxxg.com) Recently, the Ministry of Water Resources issued Announcement No. 6 and No. 7 of 2026, approving the release of five water resources industry standards, including the "Specification for Water Quality and Water Ecology Monitoring." These standards will come into effect on June 21 and 24, 2026, respectively.
The "Specification for Water Quality and Water Ecology Monitoring" (SL/T 219—2026) is a revised version of the "Specification for Water Environment Monitoring" (SL 219—2013), comprising 13 chapters and 6 appendices. The standard mainly covers monitoring station networks, surface water monitoring, groundwater monitoring, atmospheric precipitation monitoring, water body sediment monitoring, drinking water source monitoring, water ecological surveys and monitoring, emergency monitoring, mobile monitoring, automatic monitoring and remote sensing monitoring, laboratory quality assurance and quality control, data recording, processing and data compilation, etc., and is applicable to water quality and water ecology monitoring of natural water bodies other than marine water bodies. The release and implementation of this standard will provide technical support for further improving the scientific rigor and accuracy of water quality and water ecology monitoring. The *Technical Specification for Cast Iron Gates in Water Conservancy and Hydropower Projects* (SL/T 545—2026) is a revised water conservancy industry standard based on the *Technical Conditions for Cast Iron Gates* (SL 545—2011). It comprises nine chapters. The standard covers basic requirements, design, manufacturing, installation, inspection, marking, transportation and storage, and acceptance. It applies to the design, manufacturing, installation, and acceptance of cast iron gates in water conservancy and hydropower projects and other water engineering projects. The implementation of this standard will further standardize the technical requirements for cast iron gates and provide technical support for improving the quality of product manufacturing and installation.
The *Technical Specification for Pressure Regulating Valves for Fully Hydraulic Controlled Turbines* (SL/T 553—2026) is a revised water conservancy industry standard based on the *Pressure Regulating Valves for Fully Hydraulic Controlled Turbines* (SL 553—2011). It comprises seven chapters and one appendix. This standard mainly covers basic provisions, engineering design, manufacturing, on-site installation testing and acceptance, operation and maintenance, etc., and is applicable to the design, manufacture, installation, testing, acceptance, and operation and maintenance of pressure regulating valves with nominal diameters of 300 mm to 1400 mm in water conservancy and hydropower projects. The implementation of this standard will provide technical support for further ensuring the safety of water diversion systems in small and medium-sized hydropower stations.
The *Technical Specification for Soil and Water Conservation Carbon Sequestration Assessment and Accounting* (SL/T 872—2026) is a newly formulated water conservancy industry standard, containing 5 chapters and 3 appendices. This standard mainly covers the investigation and monitoring, indicator system, procedures and methods for soil and water conservation carbon sequestration assessment and accounting, etc., and is applicable to the assessment of soil and water conservation carbon sequestration capacity in regions and watersheds, as well as the accounting of soil and water conservation carbon sequestration in comprehensive water and water loss control in small watersheds, comprehensive water and water loss control on sloping farmland, silt-retention dam projects, and other ecological governance projects. The implementation of this standard will provide technical support for the scientific and standardized conduct of soil and water conservation carbon sequestration assessment and accounting.
The "Design Guidelines for Reservoir Dam Reinforcement and Upgrading" (SL/T 877—2026) is a newly formulated water conservancy industry standard, comprising nine chapters. The standard's main contents include basic data, fundamental provisions, reinforcement and upgrading of earth-rock dams, reinforcement and upgrading of concrete and masonry dams, reinforcement and upgrading of spillway and water conveyance structures, reinforcement and upgrading of other structures and reservoir banks near the dam, electromechanical and metal structure renovation, and information technology upgrades. It applies to the reinforcement and upgrading design of existing reservoir dams. The publication and implementation of this standard will provide technical support for further improving the quality and level of reservoir dam reinforcement and upgrading design in my country.
