Privies Pit Privy A pit privy is a hole in the ground, fit- ted witli a seat for comfort and a shed for privacy. It is popular because of its simplicity and has been w idely used in the past. Despite this simplicity a privy must be planned To begin with, the pit should be large enough to last at least five years before it fills up. For sizing a privy based on year-round family use in well-drained soil, estimate 600 L per person per year. Bear in mind that this figure may not apply to camping con- ventions or busy resorts, where the pit may fill too quickly for normal drainage and decomposition. Build the shed stoutly include a window, and assemble screens to keep out flies, rodents, and other carriers of filth. Metal sheathing on the outside walls may discourage porcupines. Don't forget to vent the pit. Fresh air and foul should balance themselves througli an adequate vent system, pref- erably two \ent pipes, rather than through the seat. A screen on the top of the vent pipe will discourage flies, and a sloped roof will keep out the rain. Environment Ontario supplies a working drawing on request. Well-vented and considerately used, a privy is reasonably inoffensive and should not cause odor problems. Consider also the soil in which the pit will be dug. There must be enough of it to surround the pit with m of earth in all directions around it a,s w ell as below it. The soil must have the right com- position. If it's too sandy the walls of the pit will have to be shored to pre- vent cave-ins. If it's solid cla\, the liq- uids will just sit. Idealh, the soil should be porous enough to permit liquid to seep through it, tight enough to keep liq- uids from running through too fast, and deep enough so that there will be at least m of it below the bottom of the pit before you reach rock, an impervious soil layer, or water table, ("Groundwate
