Percolation rate = Amount of water (ml) / Percolation time (min)

Percolation rate = Amount of water (ml) / Percolation time (min)

Determine the percolation rate – Refill the test holes with water to a depth of at least 300mm and then using a stopwatch see the time, in seconds, for the water to seep away from 75% to 25% full level. Download our Percolation Test Results sheet to record your findings. Divide this time – Divide the time by 150.

Determine the percolation rate by refilling each hole with water to a depth of at least 300mm and observe the time in seconds for the water to seep away from 75% full to 25% full (i.e. a depth of 150mm). 6. Divide this time in seconds by 150. This gives the average time in seconds required for the water to drop 1mm.

Vp = The speed at which the water in the test holes percolates through the soil. Any result between 15 and 100 seconds means that the ground should be suitable.

At least three test holes distributed evenly over the proposed lateral field are required. 2. Percolation test holes shall be 4 to 12 inches in diameter and to the same depth as the proposed absorption trenches (not to exceed 36 inches in depth).

The mpi, or percolation rate of a test hole (the time in minutes for the water level in the test hole to drop one inch), is determined by dividing the number of minutes elapsed by the water level drop in inches during the final measurement period.

The result of your percolation test determines how large your soakaway should be. The better the results, the smaller the soakaway. A good range is between 15 and 100. However, the closer you are to 100, the bigger the soakaway you'll need because drainage is happening slower.

Add water to provide a depth of 6 inches above gravel. Measure water levels for a minimum of 1 hour. A minimum of 4 measurements must be taken. The test must continue until 2 successive readings yield percolation rates that do not vary by more than 15 percent, or until measurements have been taken for 4 hours.

Percolation is the movement of water through soil, and the percolation rate is the speed at which that movement occurs. Percolation rate is calculated using the following formula: Percolation rate = Amount of water (mL)percolation time (mins)
