小型饮用水供应在管理方面面临特殊挑战。小型饮用水供应容易受到污染，但往往没有得到定期监测和良好维护，因此可能对使用者的健康造成影响。卫生检查（SI）是一种风险评估工具，用于确定和管理供水技术的可观察条件或集水区的情况，这些条件或情况可能有利于某些危险事件并引入可能对健康构成风险的危害。这项定性研究旨在确定世界卫生组织发布的SI工具的优点和缺点，以便为表格的审查和更新提供信息，并提高其稳健性。该研究确定了该方法的一些好处，如简单易用。还查明了一些挑战，例如检查专员之间对风险的看法可能不一致，对问题的解释可能不一致，以及缺乏后续行动。作者建议修订现有的SI表格，以应对已确定的挑战，并就可能采取的补救行动制定补充建议，以解决已确定的风险因素以及基本操作和维护。
Small drinking-water supplies face particular challenges in terms of their management. Being vulnerable to contamination but often not monitored regularly nor well-maintained, small drinking-water supplies may pose consequences for health of users. Sanitary inspection (SI) is a risk assessment tool to identify and manage observable conditions of the water supply technology or circumstances in the catchment area that may favour certain hazardous events and introduce hazards which may become a risk to health. This qualitative research aimed to identify the strengths and weaknesses of the SI tool as published by the World Health Organisation to inform a review and update of the forms and to improve their robustness. The study identified a number of benefits of the approach, such as its simplicity and ease of use. Challenges were also identified, such as potential for inconsistencies in perception of risk between inspectors, in interpreting questions, and lack of follow-up action. The authors recommend a revision of the existing SI forms to address the identified challenges and development of complementary advice on possible remedial action to address identified risk factors and on basic operations and maintenance.
