Unimproved latrines

As you know from Study Session 1, unimproved latrines, such as traditional pit latrines, do not ensure hygienic separation of human excreta from human contact.

Traditional pit latrines

A traditional pit latrine (Figure 5.2) consists of a pit in the ground without any slab. The pit may be wholly or partially lined to prevent it collapsing. The quality of these latrines is far below acceptable standards and, consequently, they pose great health risks to users and pollution risks to the environment. Latrines of this type frequently generate bad smells and are prone to insect infestation.
