Install drain under sidewalk

So I've noticed a damp smell in the house. I went under the house and found standing water. Located where it is coming from. I have a large bed in front of the house that is separated from the lawn by a sidewalk. The water is coming from 2 down spouts draining into the bed and trapping in water due to sidewalk blocking water from draining into yard. I want to put in a drain system in to divert water away from house. My question is how do I get the drain pipe under the sidewalk without taring up the sidewalk or if this is even possible. Can anyone help me with this issue?

Saw cut a 2' wide section in the sidewalk. That's all you need to run a pipe.

Go to your local home supply store, get a 4' piece of copper pipe and the fittings to attach it to a garden hose. Use a hammer to flatten the open end so the water is really squirting. Turn the water wide open and use it to blast a hole under the sidewalk. Messy but at least you don't have to cut the concrete.

There is a tool for that if you don't want to play with copper.

Most sidewalks are about 4" thick. You should be able to dig down on either side of walk and then force a pipe under the cement. We did this to supply an electrical line to a front yard light.

Better yet, go to hardware store and get kit that has the jet nozzle and hose adaptor. Install a 4' piece of PVC and you can drill a hole under a sidewalk in just a few minutes.
