Isn't there an underground subsurface station somewhere that has a big

You are wrong. It's Sloan Square Station. The sewer pipe was damaged by a bomb in WW II, resulting in raw sewage flowing into the station.

And I have a suspicion that it's not the Ty Burn, but is actually the King's Scholars' Pond sewer ? BIMBW ;-)

It's the River Westbourne. I haven't heard about the wartime incident,
but I would imagine the "sewage" the pipe contained was run-off from the
streets rather than flushnuggets.
