Glatt, the water comes in your back door? Down some steps if I recall? Yes. I just found the video. No wonder I had such a specific mental image.

Anyway.... Maybe get a big cat litter box, to collect the water, run some plastic sheeting from the edge of the lowest step that would be above the rim of the box.... Get a fast sump pump, some 1.25" pvc or whatever fits, a one way valve and some of that purple glue and elbows and rig a pipe to blow the water off and away.
