CRS Manager's Guide to PHAST Methodology

Helping CRS Country Offices to Use the Participatory Hygiene and Sanitation Transformation (PHAST) Methodology

The first edition of this manual was published by the World Health Organization in 1998. Since then, a great deal has been learned about how to successfully implement PHAST.

This manual provides updated advice based on over ten years of field-based learning. It was created in direct response to requests from CRS country programs to understand how PHAST should be incorporated into their water and sanitation projects, how to implement it at the field level, and how to train facilitators to implement PHAST at the community level.
