In South Sudan, where open defecation is standard practice, improved sanitation rates hover between a paltry 6 and 15 percent. Almost two thirds of households do not have access to sanitation facilities, and as a result, practice open defecation. Only 10% of people have access to both improved water and sanitation facilities, thus perpetuating cycles of children suffering from diarrhea, other water-borne diseases and pneumonia. Recognizing this deadly situation, PSI/South Sudan launched Expanding Access to Sanitation, a community-led total sanitation project with the goal of reducing diarrheal disease related morbidity and mortality. This brief is an overview of the program.
