Classification and grading are related to the safety of the project itself; they involve the lives and property of people living downstream. They have a direct impact on the proper functioning of the project’s benefits, its construction costs, and the speed of construction. They serve as the basis for adhering to natural and economic laws in the design process. The grade is determined based on the scale and benefits of the project, as well as its importance to the national economy; it is established by analyzing the category of the project and its role and significance within it.

The various types of water conservancy and hydropower projects—such as flood control, irrigation, power generation, water supply, and drainage improvement—constructed in different regions and under varying conditions in China are classified into five categories: I, II, III, IV, and V, based on their scale, benefits, and importance to the national economy. Hydraulic complexes and hydraulic structures must ensure safety and reliability; however, waste caused by excessive safety measures should be avoided. Therefore, in order to strike a reasonable balance between the safety and economic efficiency of such projects, hydraulic complexes and their constituent structures are classified into different categories based on their functions, benefits, scale, and importance. Different design, construction, and operational standards are then established for each category. This approach enables the designed structures to be both safe and cost-effective. Such a classification-based method ultimately achieves a harmonious integration of safety and economic efficiency. Basis for classification: Water conservancy and hydropower projects are classified into five grades based on their scale, benefits, and importance to the national economy ； Permanent and temporary hydraulic structures in water conservancy and hydropower projects are classified into five and three grades, respectively, based on the category of the project they belong to, as well as their functions and importance within the project.
Divided into five categories: l, II, III, IV, V
