We extend the conceptualization of the social and health burdens of household water insecurity on children beyond the traditional narrow lens of microbiological pathogens and diarrhea. The global burden of disease associated with water insecurity has traditionally focused on diarrheal disease as the most significant driver of infant and child mortality. However, there are many other pathways through which children experience adverse health and social consequences from inadequate or unsafe household water. We synthesize evidence of a broad range of health impacts, affecting children from infancy to late adolescence, across four domains: exposure to unsafe water; interruptions to growth and development through poor nutrition and hydration; negative social effects such as school absenteeism and interpersonal violence; and other non‐communicable health issues such as mental health, injuries, and reproductive health. The growing burden and urgency of these issues is implicated by forecasted increases in climate‐ and conflict‐induced water scarcity, human displacement, and environmental contamination in the decades ahead.
