Percolation tests

On paper, Percolation tests appear to be easy to test if you wish to have a soakaway or drainage field for your sewage treatment plant. However, the test must be carried out with pinpoint accuracy to determine the porosity of your ground. Fortunately, at Sussex Water and Drainage, we have all the equipment and knowledge to ascertain Vp measurements accurately.

The percolation test involved excavating a 300mm square hole to a depth of 300mm below the proposed invert level of the discharge pipe. After carefully removing all loose debris, we will fill the void with water to the top of the 300mm mark and leave this to seep away overnight. We will then return and fill to the same point and closely observe its time from 75% capacity to 25% capacity. Using a calculation of how much water has dispersed in the given time with the depth lost, we can accurately read the average time in seconds (Vp) for the water to drop by 1mm.

This test will be trialed at least 3 times and will be tested across at least 2 holes.

If you think a percolation test is for you, get in touch, and we’ll provide your answers!
