Barriers and facilitators to the utilisation of point-of-use water treatment systems during and immediately following flood-related disasters: a scoping review protocol.

introductionThe United Nations (UN) Sustainable Development Goal 6 seeks to ensure universal access to safe drinking water by 2030, but vast inequities in access exist, especially among vulnerable communities including limited resource, rural, disaster-affected areas. Flood disasters, exacerbated by the climate crisis, hinder the ability of individuals and families to meet essential drinking water needs and increase their susceptibility to waterborne illnesses. Point-of-use (POU) water treatment is an effective solution for water-insecure populations during and immediately following flood emergencies. However, an initial literature search identified knowledge gaps surrounding implementation of POU water systems. This scoping review aims to synthesise published evidence between January 2015 and July 2025 on barriers and facilitators to utilisation of POU water treatment systems during and immediately following flood-related disasters. The findings will inform efforts to promote resilience and agency among water insecure communities, specifically by equipping them with actionable knowledge on sustainable access to safe drinking water. METHODS AND ANALYSIS: This scoping review will be guided by the work of Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Search terms will be identified through an iterative process using the PICOT method and Boolean logic. Four databases-Scopus, PubMed, Web of Science and Google Scholar-with the addition of grey literature from UN agencies and non-governmental organisations focused on water-related issues will be searched. Two independent reviewers will apply a priori eligibility criteria to select studies. Conflicts will be resolved through discussion and a third independent reviewer absent agreement between the first two reviewers. Cohen's kappa statistic will be calculated to assess inter-rater reliability. Data extraction will be guided by predefined data points, and the Consolidated Framework for Implementation Research will guide evidence synthesis through a solution-based approach. ETHICS AND DISSEMINATION: Institutional research ethics review is not required because no human subjects are involved. Findings will be disseminated through a peer-reviewed publication, a policy brief, conference presentations and infographics for use by organisations serving flood disaster impacted communities.
