How to build an Arborloo and a Fossa Alterna
This paper gives clear instructions on how to build an Arborloo and a Fossa Alterna. The Arborloo is a shallow pit latrine that once it is full it is abandoned; the latrine house is removed, the brick or concrete “ground collar” removed to a new pit site and a new shallow pit is dug for use. The Fossa Alterna is a system of two shallow pits being used alternately. It is a sound on-site EcoSan system for small plots in rural and urban areas. The pits are usually bigger than for the Arborloo and last longer.
