- Abstract:
- Evaluation of secondary water supply system is the key basis to reflect the “last mile” of urban water supply from the source to the tap. The evaluation of supervision technology is a comprehensive evaluation of the overall construction level and management ability of the secondary water supply system, which involves many factors and hitherto lacks in-depth research. Based on the research of secondary water supply system for 175 buildings and communities in 18 representative cities in China and combined with existing research, the evaluation system of supervision technical standard was constructed, which included six core indexes, such as basic level, water supply reliability level, management system and informatization level, water quality security level, inspection and maintenance level, supervision and assessment level, and 25 sub-indexes, such as system construction period, water supply mode, management mode and so on. The analytic hierarchy process (AHP) was employed to gather expert group decision to calculate the index weight, and a comprehensive evaluation model based on the modified weighted rank sum ratio method was established. The model was applied for overall and itemized evaluation of samples from Beijing, Shanghai, Shenzhen, Tianjin, Lanzhou and Zhuhai, and the regression equation was obtained and passed the test. The evaluation had statistical significance, and the evaluation method was effective and feasible, which could be applied to the management technology evaluation of secondary water supply system of buildings and residential areas in China, and provide technical reference and theoretical reference for managers.
