The video below shows 1500 gallons of water soaking into pervious concrete in 5 minutes. That’s the equivalent of about 43 inches of rainfall seeping into the concrete with no run-off.

Just watch the water flowing for a few seconds and you get a serene feeling, somehow, all is good with the world when pervious concrete can absorb that much water. I love seeing all the spectators and the audio woman. Truly, in the land of the blind, the one-eyed man is king.

I’ve used pervious asphalt paving several times, but haven’t yet tried pervious concrete. Now I want to.
