So how much abrasive lunar regolith would we need to drive through to

water ice is pure relative to what?

Do you really need to move the mud?

Say, something like a dome open to the ground with a radiative
heatsource and a cold trap behind it.

Depends on how much water you want to lose to lunar vacuum becaues I
doubt you can seal the dome very well against the lunar soil/ice.
