Stocking up on drinking water or having a source of water to flush the toilet with (by manually refilling the tank).

Drinking water. Don't flush the toilet because you might eventually need the water in the tank too.

FYI like 90% of your comments are flagged dead, but I read through them and think they're hilarious. You might want to create a new account.

Poo in a bucket, put a lid on it. If the alternative is eventually dying of thirst or having to venture out into a contaminated neighbourhood, necessity compels.
