Also you don't want to go too deep with the sump pump.
You'll end up trying to pump out the water table, wasting
electricity.

FWIW, I think my problem right now _is_ with the elevated water
table... otherwise where would water come from when there is no rain?

Yes, but you don't want to pump more than you have to.
You can't pump a whole underground river out thru a 2 inch pipe.
I was respondiing to one of the other posters that seemed to be
suggesting solving the problem by just making the sump hole deeper.
That might work up to a point.
