Latrine Pit Excavation and Linings
Publisher: WEDC, Loughborough University, UK
The need for a latrine pit lining depends upon the type of latrine under construction and the condition of the soil. Septic tanks and aqua privies, for example, require watertight compartments so their pits are always lined. For a pit latrine, however, it is only necessary to line the pit if there is a possibility that it will collapse during its life span. This guide examines the methods and materials for lining a pit and the soil conditions that determine which options are most appropriate.
