Where There Is No Doctor 2011 139
To make the closed latrine, the slab should be placed over a round hole in the
ground. Dig the hole a little less than 1 meter across and between 1 and 2 meters
deep. To be safe, the latrine should be at least 20 meters from all houses, wells,
springs, rivers or streams. If it is anywhere near where people go for water, be sure
to put the latrine downstream.

Keep your latrine clean. Wash the slab often. Be sure
the hole in the slab has a cover and that the cover is
kept in place. A simple cover can be made of wood.

THE FLY-TRAPPING VIP LATRINE
To make the ventilated improved pit (VIP)
latrine, make a larger slab (2 meters square)
with 2 holes in it. Over one hole put a ventilation
pipe, covered with fly screen (wire screen lasts
longer). Over the other hole build an out house,
which must be kept dark inside. Leave this hole
uncovered.
This latrine helps get rid of odors and flies:
smells escape through the pipe, and flies get
trapped there and die!
