Water supply systems, in particular small-scale water supply systems, are vulnerable to adverse events that may jeopardise safe drinking water. The consequences of contamination events or the failure of daily operations may be severe, affecting many people. In Norway, a 24-hour crisis advisory service was established in 2017 to provide advice on national water supplies. Competent and expert advisors from water suppliers throughout the country assist other water suppliers and individuals who may be in need of advice during an adverse event. This paper describes the establishment of this service and experiences from the first three years of its operation. Since the launch of the service, water suppliers across Norway have consulted it approximately one to two times a month for advice, in particular about contamination events and near misses. The outcomes have helped to improve guidance on water hygiene issues at the national level.

供水系统，特别是小型供水系统，容易受到可能危害安全饮用水的不利事件的影响。污染事件或日常操作失败的后果可能很严重，影响到很多人。挪威于2017年设立了24小时危机咨询服务，以提供有关国家供水的咨询。来自全国各地的水供应商的主管专家顾问会协助其他水供应商和在不利事件中需要咨询的个人。本文介绍了该服务的建立以及其运行的头三年的经验。自这项服务推出以来，挪威各地的水供应商每月大约要征询一到两次的意见，尤其是有关污染事件和未命中事件的咨询。
