本研究的目的是:通过检查入口和出口处的微生物和化学参数，量化三个有盖储罐对分配水质量的影响；评价水库内水质的空间变异性；并对沉淀在储罐底部的沉积物的化学和微生物成分进行表征。选择位于北美一个大城市配水系统上的三座有盖水库，是因为它们具有广泛的运行特征:Cl2残余；停留时间；液压配置。这些水库由圣劳伦斯河的净化水（直接砂滤、臭氧氧化和氯化）供应。在1998年7月至1998年9月期间，每周进行一次入口/出口取样。1998年6月和9月，还进行了两次使用船只的采样活动，以评估水库内的水质空间变化。 此外，沉积物从水库底部被虹吸。本文综述了所研究的参数和分析方法。包括11个参考文献、表格、图表。

The objectives of this study were to: quantify the impact of three covered storage tanks on the quality of distributed water by examining microbial and chemical parameters at the inlet and outlet; evaluate the water quality spatial variability inside the storage reservoirs; and, characterize the chemical and microbial composition of sediments settled on the bottom of the storage tanks. Three covered reservoirs located on the distribution system of a large North American city were chosen for their wide range of operating characteristics: Cl2 residual; residence time; and, hydraulic configuration. These reservoirs are supplied by treated water (direct sand filtration, ozonation and chlorination) taken from the St. Lawrence River. The inlet/outlet sampling were conducted on a weekly basis during July 1998 to September 1998. Two sampling campaigns using boats were also performed during June and September 1998 in order to evaluate the water quality spatial variations inside the reservoirs. In addition, sediments were siphoned from the bottom of the reservoir. Investigated parameters and analytical methods are summarized in this paper. Includes 11 references, tables, figures.
