How to Build a Pit Latrine
Just a Drop has built latrines all over the world. Here's a step-by-step guide to the process, taken from one of our projects in Zambia.
16. Mike, the builder, plasters the outside wall of the fourth and final double latrine to be constructed.
14. Without the involvement of African Revival and a donation from The Holy Trinity Church in south Wimbledon, these latrines would not have been built...
13. You can see here the 2 old crumbling latrines on the right, next to the new ones under construction - what a difference!
12. Here you can see the 4 latrines in their various stages of construction, from superstructure (far right) to simple pit (far left).
11. Just weeks after work began, the first of the latrines has begun to resemble a latrine block!
This is touted as "how to build a pit latrine". My understanding is that it is wrong-headed. You should not capture all that wastage between walls. It will fill up quickly. And then?! And - it is prohibitively expensive to build these things in countries with a real school sanitation challenge. We need to spend money on books and teachers.
6. The pit foundations are continued until they are level with the surrounding ground.
5. The builder begins by building up a rectangular brick structure within the pit, slightly away from the pit walls.
4. Each pit must be 3m x 2m x 3m and the sides must be kept very straight to minimise the risk of subsidence.
3. Members of the local community helped to dig the four large pits for the new latrines, with individuals taking it in turns to provide labour each day.
2. Up until early 2011, Kinnertone School had only two latrines serving 130 pupils and several staff. One of the latrines was not even in use as the roof had collapsed making it unsafe and affording no privacy.
