Abstract:In July 2022, the Ministry of Water Resources issued the Notice on the Implementation Opinions of the "Six Mechanisms" for the Construction of Water Safety Production Risk Control. In April 2023, the Nandi Reservoir expansion project in Guangrao County was taken as a provincial pilot project of "six mechanisms" under construction water project. It adheres to pre-control on risk, priority on key issues, hierarchical control, classified disposal, source prevention and systematic improvement. It realizes the all-round control of the whole chain of safety production roughly,and effectively prevents production safety accidents. This paper reviews the experience and practice of pilot creation.Based on the analysis of the existing problems, the paper puts forward some measures and suggestions in order to provide reference for the safe construction of similar water projects
