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. WebDetermining percolation rate One of the first steps in designing a leach field is to know how quickly the soil will absorb water, this is called a percolation rate. In figuring out the physical design of a leach field you must have the following information: -Perc rate of the site ( table 1) -Daily output of the attached facility

Regions of the state are broken into the following ranges: 0 -5, 5 -10, 10-20, 20-30, 30-40, 40-50 and > 60 minutes per inch. This data can be an excellent guide in helping to refine percolation data. fischer quality constructionWebThe next step in the percolation test is to adjust the water level to 6 inches over the sand or gravel. The drop in the water level should be measured from a fixed reference point, at approximately 10-minute intervals for one hour. The drop that occurs during the final 30-minute period of time shall be used to calculate the percolation rate. fischer quarry and hauling

"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. 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. While every j… " - Order for percolation rate
