Permeable Pavement Infiltration Testing

Not sure if your permeable pavement is functioning the way it should? There is a simple test you can perform to determine if it is time for vacuuming.

You will need:

  • An 8-foot piece of unwarped 2-foot by 4-foot lumber
  • Screws and drill
  • 80 ounces of plumber's putty
  • 5-gallon bucket of water
  • Stopwatch or timepiece

Directions:

  • Cut the 2x4 into four even sections and screw together into a rectangular frame
  • Apply a 1-inch bead of plumber's putty to the frame or inside of frame
  • Place the frame in the area to be tested and apply pressure to seal
  • Apply weight to the frame to maintain the seal
  • Quickly pour contents of one 5-gallon bucket and begin timing
  • Record time for all standing water to infiltrate into the permeable pavement

Results:

If water infiltrates in less than 30 seconds, the permeable pavement is functioning as designed.
If water sits for more than 90 seconds, the permeable pavement is clogged, and a vacuum sweeper will be needed.
