What is a Percolation test (also refered to as a “deep hole test”)?
In specifying the size and type of absorption field (leach field, seepage pits, galleys, other) a septic engineer or health department official will require that a soil percolation test or “soil perc test” be performed. You may hear it described as a “deep hole test.” In brief, one or more holes are dug in the soil of the property where (or near where) a septic leach field is to be installed. Water is placed in the hole, and the engineer observes the amount of time it takes for the soil to absorb the water, or for the water to “percolate” through the soil. The engineer will also examine the exposed soil layers to obtain additional site design information.
