Interpreting Your Soil Evaluation for Septic System Suitability
A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. The results of a percolation test are required to properly design a septic system. … See more A percolation test consists of digging one or more holes in the soil of the proposed leach field to a specified depth, presoaking the holes by maintaining a high water level in the holes, then running the test by filling the holes to a … See more Some jurisdictions question the accuracy of a percolation test to assess the treatment quality of soil and instead utilize soil texture analysis--along with long-term acceptance rates (LTAR)--in place of, or in addition to, a percolation test.
