A prefabricated four-seat latrine box is shown in
figure 2-15. This box can be collapsed for shipment, as
shown in figure 2-16.
A plan view of an eight-seat field-type latrine is
shown in figure 2-17. As shown, the eight-seat field-
type latrine can be expanded to a 1 B-seat latrine. With
this type of latrine, two 4-seat boxes are placed to
straddle a 3- by 7-foot pit. After the pit is dug and before
the boxes are placed, a 4-foot-wide margin around the
pit is excavated to a depth of 6 inches, as shown in figure
2-18. A layer of oil-soaked burlap is laid in this
excavation; then the excavated earth is soaked with oil,
replaced, and tamped down to keep out surface water.
Two 4-foot 6-inch trough-type urinals are furnished
with the eight-seat latrine. Each urinal is mounted in a
frame constructed as shown in figure 2-19. A 2-inch
urinal drainpipe leads from the downpipe on each
urinal to a 6- by 6-foot urinal SEEPAGE PIT, located as
shown in figure 2-l 9. The seepage pit is constructed as
shown in figure 2-20.
A four-hole burnout field-type latrine is used at
most advanced or temporary bases. The burnout latrine
is kept in an orderly condition (daily) by camp
maintenance personnel or by the sanitation crew
assigned. Two people can effectively and efficiently
dispose of the excremental waste of 500 people. There
are two easy ways of maintaining the burnout latrine.
They are as follows: by spreading lime over the waste
material or by using diesel fuel to burn the waste
material. The burning pit for the waste material should
be located so resulting smoke, fumes, odors, and
blowing ashes do not interfere with operations or the
health and general well-being of personnel.
