Teaching the importance of sanitation and hygiene may be extended to teaching how to build simple toilets. This article describes how primary school children were taught the importance of ecological sanitation for health and for nutrient-enrichment of soils. Under the supervision of teachers, five designs of toilets were constructed, as well as handwashing devices. Urine was collected and used to water maize and other plants on demonstration plots. Local acceptance increased following open days to which local dignitaries and parents were invited.
This article describes simple, easy-to-contruct devices that can deliver water for handwashing even when water is in short supply. Together with soap, or ash if soap is unavailable, these devices have been used at home or in schools in Zimbabwe.
