box, and placing a pail under each seat. If the box is located in a building, it should be
placed against the outer wall (figure 4-8). The seats and rear doors should be self-
closing and the entire box made fly-proof. The floor of the box should be made of an
impervious material (concrete, if possible) and should slope enough toward the rear to
facilitate rapid drainage of washing water. A urinal may also be installed in the latrine
enclosure with a drainpipe leading to a pail outside. This pail also should be enclosed
in a fly-proof box.

b. Maintaining the Latrine. Pails should be cleaned at least once each day
and oftener, if necessary. The contents may be burned, buried, or disposed of by other
(NOTE: The waste will not usually be buried since the use of pail latrines indicates that
the ground is not suitable for digging.)
