Discharging Your French Drain to a Water Reservoir
We have just finished installing a french drain, we ended the pipe at the edge of this pond where there was slope down to the water. The pipe is at the bottom of the slope, flush with the grade. The water is running through some rip rap into the pond.
The water is flowing freely down to the pond. We have a steady stream of water coming through here, it’s a great way to end a french drain. You don’t need to worry about animals getting into the pipe and making it their home. If you do something like this, you need to put your pipe at the bottom, flush with the grade of the slope so the water can freely flow out.
