What you need:

  • Drain cloth
  • 18 inch diameter culvert pipe

Begin by excavating a trench along the area needing drainage. At intervals along the trench, dig holes 2 feet wide by 3 feet deep to accommodate a solid plastic culvert pipe that is 18 inches in diameter by 3 feet long.

Place a section of drain cloth over the pipe and tuck the edges into the surrounding gravel. This prevents soil from clogging the sump drain.

Run drain cloth at least one and a half feet wide along the length of the trench, covering the sump drains.

Fold the cloth over the drain rock and use cobblestones to hold the fabric in place.

Pile cobblestones or round rocks 1-6 inches in diameter along the trench. If you are unable to locate cobblestones in your area, square stones work just as well.
