This collection brings together complementary resources that collectively build a strong case for Household Water Treatment and Safe Storage (HWTS) as an effective and essential approach to improving drinking water quality at the household level. It includes a presentation that introduces the core rationale for HWTS, a global webinar exploring current trends and the evolving role of HWTS in addressing drinking water challenges, and a concise one-page summary highlighting key takeaways from the webinar.
In addition, the collection features an evidence-focused resource that examines the effectiveness of HWTS interventions, providing insights drawn from research and real-world implementation. It also includes country case studies — Colombia, Cambodia, and Ghana — each tracing how a national government has moved HWTS from scattered practice into formal water policy, and where funding, evidence, and implementation gaps still remain.
Together, these materials offer a well-rounded perspective—combining theory, global context, practical insights, policy examples, and evidence—to support practitioners, decision-makers, and educators in understanding why HWTS remains a critical component of safe water strategies, especially in settings where centralized water systems are limited or unreliable.
