Anyone who grew up with a septic system knows the risk of it backing up, especially when ones in the shower.
But for it to happen on an industrial level, that’s a whole new level of disgusting.

Leopard, you are in a unique position.
The world is crumbling around you, but its Africa so that’s normal.
You boogie too early and you risk nothing happening except your place being picked clean like aasvogels on a week old kill.
But you risk the same just going to the grocery store.

Too late and you risk everything.

There is no good or easy answer.

Except perhaps prepare for the worst, that seems the norm there.
