WebNov 1, 2001 · Because of the necessity to set upper and lower limits in design standards for septic tank practice, the percolation value is not an ideal parameter. Table 1. Values of Kfs (m/d) for various percolation rates by SR 6 and BS 6297 tests a Rate of percolation measured as tm —min/25mm. b Rate of percolation measured as ts and Vp —s/mm. WebNov 8, 2024 · A perc test determines the water absorption rate of the soil (or the percolation rate). This test is essential to understanding whether a septic system can be installed. In short, if land is rural and a municipal sewer system isn’t available, a septic system helps make a property “livable.”.
