Who is the Guide for? This Guide has been written primarily for non-specialist staff in the World Bank involved in planning, developing, or managing activities which may include urban or rural sanitation and hygiene. The Guide should also be useful for others interested in learning more about sanitation and hygiene. Scope The Guide is a concise introductory review of challenges and approaches to the management of human excreta. Broader environmental sanitation issues (e.g. drainage, solid waste management, vector control and water supply)are not directly addressed in this guide. References and links have been carefully selected to give the reader ready access to the best resources currently available. Service provision in sanitation and hygiene involves four main components that must be understood and addressed when designing or implementing a new sanitation project: institutions  required to implement and sustain improved sanitation and hygiene at scale. infrastructure itself (the physical hardware of latrines and sewers); promotion of behavior change, both for hygiene, and for household investment in infrastructure; finance required to pay for the infrastructure and promotion
