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. WebThe infiltration rate of a soil is the velocity at which water can seep into it. It is commonly measured by the depth (in mm) of the water layer that the soil can absorb in an hour. An infiltration rate of 15 mm/hour means that a water layer of 15 mm on the surface of the soil, will take one hour to infiltrate (see fig. 33). Fig. 33.

WebHow to Order a Perc Test If you're ready to hire a pro to evaluate your property, all you need to do is call your county health department (just Google the county name and then “Health Department” to find their phone number) and ask them what the requirements are to properly conduct a perc test.
WebThe percolation rate out of the bottom of the soil layer is also defined by the constant rate while the soil layer remains saturated. Percolation stops as soon as the soil layer drops below... dutchmodelshopA 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. In its broadest terms, percolation testing is simply observing how quickly a known volume of water dissipates into the subsoil of a drilled hole of known surface area.
