The World Health Organization estimates that contaminated drinking water causes 502,000 diarrheal deaths each year and that by 2025, half of the world's population will be living in water-stressed areas. ADB is committed to provide safe drinking water throughout Asia and the Pacific. This handbook was prepared for ADB project officers as a guide toward efficient integration of the Water Safety Plan (WSP) approach into ADB's urban water operations. The WSP is a tool that assists water suppliers and other stakeholders to identify and prioritize system needs. This publication provides a step-by-step guide on developing and implementing a WSP using guidelines, templates, evaluation criteria, and terms of reference for early technical assessments and project preparatory technical assistance stages.
