Storm Water Management by Pervious Concrete - PCA

Pervious concrete creates a very porous medium that allows water to drain to the underlying soils. It is commonly produced to allow as much as five gal/ft²/min to pass through the body of the concrete. By allowing rain events to penetrate the pavement to the underlying soils, the first flush of the paved surface is contained on site.
