c. Trough Urinals.
(1) Trough urinals. If wood and sheet metal are more readily available than
pipe and a more permanent facility is desired, a trough urinal (see Figure 3-9) may be
built. This 10 foot trough may be either U-or V-shaped and made of sheet metal or of
wood. If wood is used, the trough should be lined with heavy tarpaper or metal. The
legs at one end of the trough should be cut slightly shorter so the liquid will flow
downward, into the pipe, and then into the soakage pit.
(2) Chemical latrine urinals. When troughs are included and attached to
the inside wall of a chemical latrine, the pipe is connected to the trough to drain the
liquid into the latrine holding tank.
