Downspout French Drain Design. The french drain is meant to protect a new retaining wall we built for a gravel pad for our new shed from getting too much water all the time. When it rains a 2000 sq ft roof gathers 1160 gallons of water in a 1 inch rainfall. This structure can be attached to your downspouts and will work seamlessly with your existing gutters.
Note the shed retaining wall gravel pad are just feet from the neighbor s yard. The french drain is meant to protect a new retaining wall we built for a gravel pad for our new shed from getting too much water all the time.
