Abstract Due to uncertainties in water supply, there is growing demand for water resource management in enterprises. In this study, we evaluated the effects of companies’ water-saving reconstruction projects. We used Hina Advanced Materials Company as a case to construct an investment decision model to (1) calculate the internal and external costs of water resources based on circular economic value analysis theory, and (2) locate the level of water resources circulation. We adopted gray situation decision analysis to identify the typical problems that occur in water resource utilization. Moreover, we demonstrated optimization plans for different potential improvements, thereby providing guidance and references for water resource cost management and the comprehensive optimization of environmental benefits. We concluded that the circulation economic value analysis model can effectively display the flow and amount of value derived from water resource flows, thereby providing guidance and suggestions for optimizing water resource flows.

Introduction
Nearly half of China’s water resources are substantially polluted as urbanization accelerates and industrial sewage is discharged irresponsibly. Some serious water pollution events, such as the contamination of Songhua River with benzene, algae water pollution in Taihu Lake, and Jingjiang water pollution, have caused adverse social impact and immense economic losses, which significantly threatens the sustainable development of society and the daily life of residents. The ternary materials industry has received widespread attention from the public due to the massive amount of wastewater discharged from its production processes which results in significant environmental pollution. This industry has a water consumption of 10 tons per ton of product and a low utilization rat
