With large-scale industrial parks developing, concern regarding much evaporation and its spillover impacts on water environment and water ecology has grown significantly in recent years. However, traditional water audit is hard to meet needs for the collaborative management of water environment and water ecology based on evaporation (3E), which requires a multi-dimensions evaluation. The purpose of this paper is to accurately evaluate industrial parks' impact considering the water life cycle. This paper proposes a systematic 3E water audit method that contains a logical framework and a comprehensive evaluation index system with 5 dimensions and 25 indexes, then applies it to a typical Iron and Steel Industrial Park in China. The results presented the 3E audit score of the Chengsteel IP was 89.91, suggesting comprehensive performance is good. The score and grade of every index especially quantity of water evaporation per ton steel were provided. This paper indicates that the new method developed can systematically evaluate the impact of industrial parks. In addition, our analysis highlights the different management strategies and practices that relieve impacts of the whole water use process on legal, eco-environmental, economic, social, and technical dimensions.
