Any discussion of on-site sanitation must start with pit latrines. This is because they are one of the oldest forms of formal sanitation in the world and for many they are still the best. This guide introduces the types of pit latrines that are commonly used in low-income communities and the factors that will help determine which type is most suitable for any given circumstance. Detailed information about particular designs is presented in further guides in this series.
