6-32. DRAINAGE DEVICES FOR WASHING UNITS
As an aid in draining the washing units, one of the following devices may be
a. Common Outlet. Connect all three cans to one central outlet pipe. When
the washing has been completed, the valve may be opened and the water drained out.
The water so removed should be passed through a grease trap and then into a soakage
b. Bunghole and Pipe. Cut a hole in the bottom of the drum and weld a pipe
coupling into its place. Screw a short piece of pipe, about four inches longer than the
depth of the water, into the fitting (figure 6-24). The pipe should be screwed in by hand
so that it can be removed easily. When the drum is to be drained, the pipe is removed.
With this arrangement, it is necessary to build a soakage pit under the device or to
construct a trough under the containers and run the water into a grease trap and then a
6-33. IMPROVISED HANDWASHING DEVICES
Handwashing devices must be provided outside latrine enclosures and near or
adjacent to kitchens. They may also be set up at other points in a bivouac area. To
encourage their use, they should operate easily and should be kept filled with water at
all times. Two cans should be provided and both containers checked frequently to see
if refilling is needed. All of these devices should have a shallow area dug out under the
outlet. The area should be filled with small stones. This soakage bed will prevent the
water from gathering into pools. The simplest handwashing devices may be made from
salvaged 5-gallon water cans or from number ten size food cans.
a. Five-Gallon Water Cans. When using five-gallon water cans, punch a hole
in the cap and suspend the can from a support. By having the cans arranged as shown
in figure 6-25, they may be tipped to permit a flow of water.
b. No. 10 Size Food Can. Figure 6-26 shows an improvised handwashing
device that utilizes a perforated number ten food can as a sprinkler. This device is
suitable for installation and use near latrines and messes. An improvised dipper may be
made from a small food can plus wood, wire, or sheet metal for the handle.
