I have a comment/suggestion.. It is that I'm jealous.
I agree, wire up for anything thing you even dream you may want to power, now. I ran lots of wire and a bank of 4x4 outlets. Then I ran a bank of light switches and each switch controls power to a 4x4 outlet. Then I put some cross boards up high under the tank in the cabinet. Then when I plugged everything in I ran the cords up over those cross boards and to the specific outlet. It is tidy and I can kill anything by flipping a labeled light switch. Do the same basic thing at your sump but in a different location. 4x4 boxes, outlets, and light switches are way too cheap not to do while you are at it.
