One advantage of a smooth-wall pipe is that it will drain water quickly, and if it gets clogged, you can use a drain snake to clean it out. In this system, the pipe is solid, and not perforated, so there’s no need to provide gravel for drainage along the length of the drainpipe.

Then bury a plastic catch basin at the source and connect it to the discharge with PVC drainpipe. To create the drain, you’ll have to dig a gradually sloping trench from the source to the outlet. from the inlet, it would have to be about 1 ft. The drainpipe should slope downhill at least 1/8 in. Yard drains might be an answer, if there is a low spot for the discharge. If the extension crosses over a sidewalk, it becomes a trip hazard.

Long downspout extensions that carry rain water from the house is a good way to keep it away from your foundation. Fasten the hose to the pipe, turn on the water and pressure wash out a hole under your concrete slab where you want the 4 inch pipe to pass.Getting rain water away from the house is a good thing On the other end of the pipe solder a fitting that can be threaded onto a garden hose. Another way I go under concrete is to dig a trench on one side of the slab, get a 1/2 inch copper pipe cut to the length of the hole, in your case about 5 feet, take a hack saw and cut one end of the pipe at a sharp angle and solder a brass nut (a number 10 nut should work) inside the pipe at the base of the angle. If I did this for approximately 20 feet, 5 feet should be a snap. There is a lot of sand in my soil so it was not really too difficult.

It took me approximately and hour of driving to get 20 feet of the pipe through. I would pull the pipe out every foot and clean out the dirt. I dug a trench about 15 long and 3 feet deep and started the hole by twisting the pipe as I hammered on the outer end with a small sledge hammer. Using 4 inch by 10 foot ABS plastic sewer pipe with notches/teeth cut in the end, I drove approximately 20 feet under the slab of my small barn. I am assuming that you want to go across the 5 foot side walk and not the length.
