Right on, John, 4" drain pipe is cheaper, lighter to work with, easier 
to cut, and is as good for conduit as the more expensive pipe intended 
for water pressure.  Most of us don't put a hundred or more lbs of 
pressure in our conduits so why pay for that capability.  You do need to 
be careful backfilling when using S&D (Sewer and Drain) as it is easier 
to damage with sharp rocks, large dry dirt clods of sun baked clay, and 
the like.  Also it has to be well buried if it is to be driven over so 
the down forces of tires will be distributed sufficiently. If buried 
quite shallowly and the soil gets really wet then driving over it could 
cause a problem. I bury mine at least a foot, sometimes 18 " or more and 
have never had a problem with traffic over my conduit including a semi 
full of gravel, a cement delivery truck, etc.

You may not  N E E D  a 4 inch conduit now but it could give you room 
for future growth. I've never heard anyone complain about more wires 
being too easy to pull into a conduit.
