Faced with limited space to dig latrines in some parts of the Farchana refugee camp in Chad and the collapse of latrines in sandy areas, SECADEV (a Chadian NGO) has been testing its own form of ecological toilet - family latrines that can be emptied. The ecological sustainable part is that space is saved (there is no need to dig new pits as they can be emptied when full). Furthermore, faeces are supposed to be reused for agricultural purposes.
