Intervention: Hardware
Description: Community sessions will be provided to each of the sub-villages (n=27) teaching participants how to build a tippy tap, how to build an improved latrine, and how to make liquid soap. In addition, an existing water gravity flow scheme will be rehabilitated and extended, 350 tippy taps and 350 pans for pour flush latrines will be distributed, and sanitation blocks will be built in four schools. Within these schools, SWASH school hygiene clubs will be organized.

Intervention: PHAST
Description: PHAST sessions are based on the 'PHAST step-by-step guide: A participatory approach for the control of diarrhoeal disease' of the World Health Organization. Considering the overlap with some CLTS activities, only a selection of the full guideline will be enrolled, namely: 1) Health problems in our community, 2) Good and bad hygiene behaviors, 3) Investigating community practices, 4) How diseases spread, 5) Blocking the spread of disease, 6) Selecting the barriers, 7) Choosing sanitation improvements, and 8) Choosing improved hygiene behaviors. These 8 activities will be enrolled in approximately 40 community groups. Each activity will take between 30 minutes - 2 hours to complete.
