The design of a simple latrine slab is a basic structural problem for an engineer. However, as the slab forms a critical part of a sanitary facility for most people living in low-income countries, the design criteria also need to include issues relating to user preference, culture, gender, health, economics, maintenance and sustainability, as well as those related to construction where size, shape and surface finish are features that need to be considered alongside those of strength and durability.
