Figure 4-11. Trough urinal.
(5) It is a good practice to construct urinal facilities throughout the unit area.
If, however, the urinal facilities are located some distance from the sleeping area, a
large can or pail may be placed at a convenient location in the area for use as a urinal
at night. The can used for this purpose must be emptied into the soakage pit or pit
latrine every morning and washed with soap and water before being reused.
(6) When a urine soaked pit is to be abandoned or has become clogged, it
should be sprayed with residual insecticide and mounded over with a one-foot covering
of compacted earth. The site should then be marked with a sign as indicated in
paragraph 4-9, if the tactical situation permits.
Section IV. LIQUID WASTES
4-17. KITCHEN WASTES DISPOSAL FACILITIES
Liquid wastes from food service operations contain particles of food, grease, and
soap. This liquid requires some kind of treatment before it is allowed to drain into a
sewer or is disposed of by other means. (Grease and oil can cause the soil to lose
some of its ability to absorb liquids--that is, to "clog up.") In permanent or
semipermanent camps, liquid waste is passed through a grease trap before it enters the
sewage system. In temporary camps, grease traps are used to take the grease from
the liquid before the liquid then enters a soakage pit or a soakage trench.
