        The hole would be 0.5m wide and >1000m deep, backfilled with bentonite clay and concrete. At the bottom, the path curves back upward, so waste is not stored at the bottom.

        Even if geology doesn’t collapse the hole, it’s hard to imagine material climbing up through 1000m of clogged pipe.
