Used to do this all the time when I was a linesman.
The easiest and safest way to do this is to use a vacuum on one end. Tie a
parachute or streamer to a string and put that in the pipe while someone's
sucking on the other end. Make sure you hold the twine with a screwdriver
and not your fingers cause it'll usually go pretty fast.
Now, if that won't work, this will. Same thing on the string part but use a
jackhammer type air compressor. You'll put your parachute/streamer in the
conduit, then wrap a rag around an air hose. Put that assembly into the
pipe but make sure that it's not binding where the string goes in. Then
have someone else hold the string and yet another run the air compressor.
Be VERY careful with this method. Things (sometimes very nasty things) come
flying out the other end at a VERY high rate of speed. I learned the hard
way that you don't want to be the guy standing in the manhole when things
start moving.
Have fun, be super careful.

Subject: [WISPA] bare conduits
Im looking at a project that requires connectivity between multiple
buildings on the same campus. There are 4" conduits connecting each
facility. The conduits are bare, Id like to run fiber in them, and
there are no pull cords in them. Some are several hundred yards long.
Ive heard that you can blow a cable through a conduit. Can anyone
enlighten me on equipment/technique for this application?
Thanks
Chris
