Emergency toilet use without flush ability. remove water. Line pot with trash bag. Have a pail of wood ash, quicklime, kitty litter or sawdust available so that after each duty is done, the offender can sprinkle a liberal amount over it. This will keep the smell down. You can take it outside and bury it in a deep hole out of the way. If the water goes off and stays off this will work. Especially in a survival situation.
