Pervious concrete is a porous paving material which permits rain and storm water run-off to percolate through it rather than flood surrounding areas or storm drains. Though it is available from many concrete plants, it is only one key ingredient to a porous paving system. If you enjoy drinking water, washing your car or watering your lawn, you depend on Florida's aquifer. Year after year it's level is dropping, and more and more pollution, especially from parking lots and other paved areas is getting into it.
Pervious concrete is part of the solution.
First, it greatly reduces run-off, returning much storm water to the aquifer through its subbase. Second, the pervious concrete acts as a filter catching much of oils and polluting chemicals that flow dissolved in or suspended by the storm water. When the sun comes out much organic material evaporates or is broken down by heat or ultraviolet rays. Thus it becomes a renewable filter. Third, it may reduce or eliminate the need for subterranean storm sewer drains.
