The indigenous knowledge of our ancestors provides valuable information on how to prevent negative health impacts on water hygiene in the event of drought. The present study aimed to explore the role of indigenous knowledge in maintaining water safety in drought conditions. A qualitative content analysis method using in-depth semi-structured interviews was used to collect and analyze the data. The current research was carried out from April 2017 to June 2018. A purposive sampling method was used to select 15 participants. Trustworthiness was applied with the Lincoln and Guba approach and data were analyzed using Graneheim and Lundman's method. Two categories including drinking water storage and water collection were extracted from the data. Each category includes different strategies to deal with water. Water storage includes water quantity and water quality. Water collection consists of collection methods and rules. Indigenous knowledge is an indispensable component of community disaster resilience. It can be transferred to other communities and employed to empower affected communities. But using the knowledge without scientific considerations cannot guarantee peoples' health throughout the drought periods.

我们祖先的本地知识为干旱时如何防止健康对水卫生的负面影响提供了宝贵的信息。本研究旨在探讨土著知识在干旱条件下维持水安全方面的作用。使用深入的半结构化访谈的定性内容分析方法来收集和分析数据。当前的研究于2017年4月至2018年6月进行。目的抽样方法用于选择15名参与者。通过Lincoln和Guba方法应用可信度，并使用Graneheim和Lundman方法分析数据。从数据中提取了两类，包括饮用水存储和水收集。每个类别都包括处理水的不同策略。储水量包括水量和水质。集水包括收集方法和规则。土著知识是社区抗灾能力不可或缺的组成部分。它可以转移到其他社区，并用来增强受影响的社区的能力。但是，在没有科学考虑的情况下使用知识无法保证人们在整个干旱时期的健康。
