Interpretations and Explanations

A bored-hole latrine is a hole drilled in the ground to receive and store bodily wastes. It is similar to a basic pit latrine, but the pit is a hole bored with a soil auger, either mechanically or manually. A floor slab of wood or concrete is placed on top.The borehole diameter is recommended to be at least 0.4 metre, and the pit is 4–10 metres deep. The relatively small diameter permits a simpler, smaller, lighter and cheaper floor slab and foundation, but limits the storage capacity. A bored-hole latrine is suitable for stable, permeable soils, free of stones, and where the groundwater is deep beneath the surface. The top 0.5 metre of the pit is often lined to provide support for the slab, but the pit is not lined all the way to the bottom. It is mainly used in emergency situations (WHO et al. 2003).
