Set Up, Construct, and Maintain Field Waste Disposal Devices |
EQUIPMENT NEEDED:
- Set up required number of chemical toilets.
Collect material for type of improvised facilities to be constructed, if required.
Establish a detail to set up or construct the devices.
DISPOSAL METHODS THAT MAY BE USED IN THE FIELD:
NOTE
Local, state, federal, and host-nation regulations or laws may prohibit
burning or burial of waste. The garbage, rubbish, and other such material
may have to be transported to a waste disposal facility. Chemical toilets
are the required human waste disposal devices for use during field exercises
or missions. Improvised devices may be used under emergency conditions;
the burn-out latrine is the preferred method for improvised devices.
- Garbage/rubbish disposal.
- Collect and transport to approved disposal facilities.
- Expedient devices.
- Burial—Less than 1 week.
- Incineration—Longer than a week.
- Liquid kitchen or bathing waste disposal.
- Grease trap.
- Soakage pits.
- Evaporation beds.
- Human waste disposal.
- Chemical toilets. Urinals should be provided in these facilities to prevent soiling
the toilet seats, if possible.
- Individual waste collection bags on the march or for small groups in isolated
areas.
- Cat-hole latrine for marches if individual waste collection bags are not
available.
- Field expedients when individual waste collection bags are not available—
- Burn-out latrine.
- Pail latrine when chemical toilets are not available, the ground is too hard,
or the water table is too high (soil is very wet).
- Straddle trench for 1 to 3 day bivouac sites when burn-out or pail latrine
are not available.
- Deep pit latrine for temporary camps.
- Soakage pits for urinals at temporary camps.
- Trough urinal.
- Pipe urinal.
- Urinoil. (See page A-44 for further information on the urinoil.)
STEPS OF PERFORMANCE:
STEP 1: Use the following chart to determine disposal requirements.
STEP 2: Select site of construction.
- Garbage and soakage pits should be at least 30 meters from food service.
- Latrine should be as far as possible from food service (100 meters or more
is best).
- Latrine should be located on level ground. Never uphill from the campsite or
water supplies.
STEP 3: Construct disposal facility.
Garbage pit—Used to prevent accumulation of
garbage in the unit area.
NOTE
Garbage and rubbish should be transported to
an approved landfill or must be buried or
burned. If buried for short stays, cover daily.
For longer periods, garbage and rubbish may
have to be burned; however, the ashes should
be buried. (Reader should consult the note
on page A-32.)
Soakage pit/trench—Used to prevent accumulation of liquid waste (water
from showers, sinks, and field kitchens).
Grease trap—Used with both soakage pit and trench to prevent clogging of soil.
Cat-hole latrine—Used only on the march (if individual waste collection bags
are not available) and covered immediately after use.
Chemical toilets—Used as the standard field latrine.

Straddle trench latrine—Used on short bivouacs and field training exercises. Two trenches per 100 males and three trenches per 100 females.
Deep pit latrine—Used for longer periods of time and in built-up areas. Collapsible two-seat boxes are available in the supply system.
NOTE
If ground is too hard for digging, or if the water table is too high, use a pail
latrine or a burn-out latrine.
Pail latrine—Use where water table is too close to the surface of the ground
for digging a deep pit latrine.
Burn-out latrine—Use where water
table is too close to the surface of the
ground for digging a pit latrine, or
stay is for an extended period.
Urinals—For male latrines,
construct one of the following
urinals: trough urinal, pipe
urinal, or urinoil.
TROUGH URINAL
PIPE URINAL
URINOIL
STEP 4: Inspect daily to make sure that the following is done:
STEP 5: Close improvised latrines and garbage pits when filled to within 1 foot of
the ground surface. Have chemical toilet contents removed daily.
Close out by—
- Spraying with residual insecticide.
- Packing earth in successive 3-inch layers until mounded 1 foot above ground
level. Spraying again with residual insecticide.
- Posting a sign stating, “Closed latrine/garbage pit and date” (except in combat).
