20.1  Types of latrine

In Study Session 19, sanitation facilities were classified as improved or unimproved, and alternatively as wet or dry systems.

  • Three types of dry sanitation technology were included in the list of improved facilities in Study Session 19. What were they?

  • Pit latrine with slab, ventilated improved pit (VIP) latrine and ecological sanitation.

Pit latrines are basic structures that can be adapted easily into different types of latrines such as VIP latrines and ecological sanitation systems. These other latrines share many common features of simple pit latrines; therefore, focusing first on pit latrines will help you to understand the other sanitation technologies as well.
