Shame and disgust are strong behavioral drivers. With this in mind, this posters and leaflets challenge the existing social norm that defecating outside is acceptable. The images are shocking but have proven to spark discussion and self-realization that all people should use a toilet, drink clean water, and wash their hands.


This is a flip chart that tells the story of Achey and Achroch. Achey’s family is a role model and shows how one family can construct a toilet. Through the use of open questions at the end of the story, participants see the benefits and costs of building a toilet.


In a proposed one-hour training, this F-Diagram is used after the Achey and Achroch flip chart. Participants are asked to brainstorm the different ways feces can reach your mouth. When participants identify a correct answer, they are given a visual aid of the transmission channel and asked to affix it on the poster.


The Stepping Stones activity physically encourages people to take the steps to build a toilet. They line up in two teams and they race to take the steps while shouting the steps out loud. This lively activity encourages movement and physical activity for a dynamic environment.


This short video tells the story of Village Chief, Choern Sok who believed his village would be significantly healthier if everyone had a latrine, so much so that he worked with other village leaders, families, schools, and health centers to make buying toilets a community priority. Three months after he began his movement, 100% of the families in his village had their own latrine.
