I’m filing that in the “need to remember” part of my brain.
Ok, let’s get technical. How to make a cammode -
First, steal a cammode. Any one will do, doesn’t matter if it is low-flow, energy-saver, any of that. But making that complex porcelain thing is going to beyond anybody, in a zombie apocolypse.
Got the throne? Good, you are about done.
You next need three barrels ... if you plan to stay in the area. One, if not.
First, put a rain barrel above the john. Plumb it into the crapper’s water source. Dig a hole under the crapper, and you have a working john.
The one is for a rain barrell.
If you intend to stay ... you need two more barrels.
Plumb the waste from the crapper into the first, let it stew, then plumb it into the second all via a gravity-feed system - this is called a septic field. Let the second barrell leak, the waste goes away.
Ironically, years ago, ago, there was an article on FR - “Septic Fields Leak!”
Well, no stuff. That is what they are designed to do.

If your standard water supply has failed but you have an alternate source (rain, a pond, whatever), you can flush a toilet by dumping a bucket of water into the bowl. Or, you can dump the water into the toilet’s holding tank and then it flushes normally.
