Cleaning Exterior Drain Pipe

My one-car garage sits at the bottom of a down-slope. Many years ago, a concrete channel drain was installed which feeds the water into a 5" diameter PVC drain pipe which drains to a brook/swamp area. Over the years, sand, dirt and whatever have accumulated in the bottom of the drain pipe reducing the flow capacity of the pipe.

What would be the best method of cleaning this PVC drain pipe? When I insert a narrow hoe blade, I can clean about 4 feet and I always pull out an accumulation of dirt, leaves, etc. However, the drain is over 100 feet in length. I considered renting a drain cleaner but am not sure if it would clean out the mud sitting in the bottom of the pipe. Flowing water from a hose just doesn't seem to do the job.

Any suggestions are appreciated.

Rent the drain snake with a 4" or 5" tip. Run water in the top of the drain and the snake in from the bottom. That way as the snake loosens the sludge it will be washed out by the water without completely clogging the pipe. Be sure to follow all safety instructions with the snake especially the wearing of heavy leather gloves.
