Four of these five shots were taken from roughly the same vantage point.
All of this action happened between October 1 and 3, 2017.
The underground trench is about 50 feet long, 4 feet wide and 3 feet deep.
It is wrapped in heavy duty non woven geotextile fabric and filled with clean gravel.
Downspouts connect to an 8 inch perforated pipe that runs through the middle of the trench and allows roof runoff to seep back into the ground without erosion.
The infiltration trench was built to specs of Pennsylvania Dept of Environmental Protection:
Pennsylvania Stormwater Best Management Practices Manual Chapter 6.4.4
