A percolation test is a special soil test 1 that evaluates the soil’s ability to accommodate a septic system to dispose of sewage under the ground. A perc test evaluates both the soil and the site to determine whether a septic system can be installed on the property. The percolation rate refers to the soil absorption rate, or how quickly soil absorbs water. This is important because a septic system installed in a location with poor percolation could lead to significant sewer backup, soil degradation, and structural issues for homes and buildings, in addition to health and safety concerns.

Some towns require additional “hydraulic” soil tests for sites that test above 30 minutes per inch.
