Others have given good advice. My project was the same as yours. I
didn't try to make the hole neat, just rented a rotohammer, drilled
lots of holes (it doesn't take long), then beat the piss out of it with
a sledge. That also didn't take long. Not much of a mess either. I
wasn't concerned about 'neat' as I needed to chisel a trench along two
sides of the basement to channel water to the sump (no way to put drain
lines outside due to patios, etc. Now that project was fun, hours and
hours during a winter of using a single jack and getting sore fingers
picking broken concrete out of the trench.

a couple thoughts....

if you live where it freezes put pump in a heated space so the line
from pump to discharge doesnt freeze, remember the pump will have a
check valve.

its important to consider where your discharging the water. IF YOUR
HOME IS ABOVE GROUND LEVEL THINK ABOUT FORGETTING THE PUMP you may be
better off draing the underfloor water away from the building.

do realize a sump pump is only works when the power is on.

i had a basement flood because of storm Ivan, it doid lots of damage
right when I was trying to sell the house.

I should of drained the water to the front of home well away from
foundation

I have now installed 5 sump pumps in three different houses over the
pasts 30 years. Not one of them had an internal check valve. I had to
install an in-line one for each. Of those 5, 3 were pedestal types and
2 the immersion types.

You can get pumps driven by water pressure (from the potable supply line).
You water bill may be high, but you won't have a water-damage repair bill.

Ooops. Hit 'send' too soon. Your point about protecting the line from
freezing is very good. Only the line needs protecting though as the
pump won't freeze in a normal basement. Of course there are always
exceptions and in really severe climates, the pump itself might need
protecting.
