Before digging … 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. citizens advice make an appointment
