Abstract：
As drinking water travels from its source, through various treatment processes, hundreds to thousands of kilometres of distribution network pipes, to the taps in private homes and public buildings, it is exposed to numerous environmental changes, as well as other microbes living in both water and on surfaces. This review aims to identify the key locations and factors that are associated with changes in the drinking water microbiome throughout conventional urban drinking water systems from the source to the tap water. Over the past 15 years, improvements in cultivation-independent methods have enabled studies that allow us to answer such questions. As a result, we are beginning to move towards predicting the impacts of disturbances and interventions resulting ultimately in management of drinking water systems and microbial communities rather than mere observation. Many challenges still exist to achieve effective management, particularly within the premise plumbing environment, which exhibits diverse and inconsistent conditions that may lead to alterations in the microbiota, potentially presenting public health risks. Finally, we recommend the establishment of global collaborative projects on the drinking water microbiome that will enhance our current knowledge and lead to tools for operators and researchers alike to improve global access to high-quality drinking water.
摘要：
当饮用水从源头流出时，通过各种治疗过程，数百至数千公里的配电网络管道，私人住宅和公共建筑的水龙头，它面临着许多环境变化，以及生活在水中和表面的其他微生物。这篇综述旨在确定从源头到自来水的整个传统城市饮用水系统中与饮用水微生物组变化相关的关键位置和因素。在过去的15年里,独立培养方法的改进使研究能够让我们回答这些问题。因此,我们开始着手预测干扰和干预措施的影响，最终导致饮用水系统和微生物群落的管理，而不仅仅是观察。实现有效管理仍然存在许多挑战，特别是在前提管道环境中，表现出不同和不一致的条件，可能导致微生物群的改变，潜在的公共卫生风险。最后,我们建议建立关于饮用水微生物组的全球合作项目，这将增强我们目前的知识，并为运营商和研究人员提供工具，以改善全球获得高质量饮用水的机会。
