The downspout is connected to a buried pipe that carries rain water away from the house.

The rain water is carried into a large hole filled with gravel. The vertical pipe is perforated to allow the rain water to percolate into the gravel. A geotextile filter cloth is installed around the excavation to prevent soil from contaminating the clear gravel.
