The direct measurement yielded by a percolation test tends to overestimate the infiltration rate, except perhaps in cases where a BMP is similarly dimensioned to the borehole. As such, adjustments of the measured percolation rates were converted into infiltration rates using the Porchet ...

WebThe percolation test calculations for soakaway installation are as follows: Area (A) = V x P x 0.20 for sewage treatment systems. Area (A) = V x P x 0.25 for septic tanks. V = the time in seconds for the water in the test hole to drop by 1mm. P = the maximum number of persons that the treatment system/tank is designed to serve.
