only a slight odor. Other modifications of waste disposal methods are possible and
should be used when they are more adaptable to the particular situation.
OTHER WASTEWATER FACILITIES
a. Noninfectious and Other Waste. Every device that is used for washing or
drinking in the field should have a soakage area of some kind under it to prevent pools
and mud from forming.
(1) Construction. The area under and a few inches around individual
handwashing devices, wash racks, and Lyster bags should be excavated a few inches
and filled with small, smooth stones to form a soakage pit for spillage. Wastewater from
wash racks should pass through a grease trap before it enters a soakage pit or soakage
trench. A soakage pit or soakage trench should also be used with each field shower
device; however, no grease trap is required under showers.
(2) Sanitation. The same sanitary principles should be followed as with a
soakage pit or trench.
b. Infectious Waste.
(1) Types of infectious waste. Infectious liquid waste or waste which is
potentially infectious includes sputum, surgical dressings, swabs, disposable diapers,
culture media, pathological tissues, bloods clots and blood, live vaccine containers,
syringes, and other materials from infectious patients.
