Does flushing it down the toilet qualify? It seems to me that it qualifies. When flushed, excrement is moved to a location (a sewage line or septic tank) that is outside the “camp” (your home), already dug, and already covered, thereby preventing the “camp” from becoming “indecent” (unsanitary). That's the whole reason why sewage systems were invented: it's more convenient and can handle far more excrement than simply burying it in a hole in the backyard.
