This study presents the efficiency of a drinking water treatment plant from Constanța, Romania. Individual and aggregated indices are proposed and built using nine water parameters for this aim. The analysis of individual indices permits the detection of the period of malfunctioning of the water treatment plant with respect to various parameters at various sampling points. In contrast, the cumulated indices indicate the overall performance of the treatment plant during the study period, considering all water parameters. It was shown that the outliers significantly impact the values of some indices. Comparisons between the simple average and weighted average indices (built taking into account the importance of each parameter) better reflect the impact on the water quality of some chemical elements that might harm people's health when improperly removed.
本研究展示了罗马尼亚康斯坦察一座饮用水处理厂的效率。为此，使用九个水质参数提出并构建了单独指标和综合指标。对单独指标的分析有助于检测水处理厂在不同采样点针对各种参数的故障时期。相比之下，综合指标则表明了在研究期间考虑所有水质参数时处理厂的整体性能。结果表明，异常值对某些指标的值有显著影响。简单平均指标和加权平均指标（构建时考虑了每个参数的重要性）之间的比较能更好地反映某些化学元素对水质的影响，这些化学元素若去除不当可能危害人体健康。
