In conducting a percolation test, the following flow chart must be used to determine which test procedure to follow:
1) | Fill the percolation hole with water to a depth of at least 12 inches over the aggregate. Determine the time needed for the water to seep away completely. | |||||||||
2) | Fill the percolation hole with water again to a depth of at least 12 inches over the aggregate. Determine if the water seeps away in 10 minutes or less. | |||||||||
3a) | If water is left in the percolation hole after 10 minutes, proceed with the PRESOAKING PROCEDURE, followed by the SLOW PERCOLATION TEST PROCEDURE. | 3b) | If the water has completely seeped away after 10 minutes, proceed with the FAST PERCOLATION TEST PROCEDURE. |
