Application Study on Industrial Water Efficiency Evaluation by First-Order Directory Sampling

In the implementation process of the strictest water resources management system, based on the sampling survey method which is characterized with low cost and high efficiency, the first-order directory sampling method is designed to test one area value’s truth of water consumption of ten thousand yuan industrial added value which is reported by itself and, water consumption of ten thousand yuan industrial added value is a red control line evaluation index which can measure the management level of industrial water efficiency. From the first-order directory sampling application process and the results in above-scale industry of Hubei Province, it is tested that the first-order directory sampling can evaluate the index of water consumption efficiency with high accuracy and, this method is easy and low-cost. If it is applied to the practical evaluation, the result of inspection can reflect the real and comprehensive industrial water efficiency. Then the most strict water resources management system can be promoted and implemented.
