  • Are you planning on installing a soakaway? Are you in need of a percolation test to give you an understanding of the size that your soakaway will need to be?
  • Or are you having land drains installed? Are you in need of a percolation test to determine the sizing for the land drains?

What is a percolation test?

A percolation test determines the water absorption rate of the soil, in preparation for a septic drain field (soakaway) or land drain. A percolation test is required in order to properly design the soakaway you require. The results of the test supplies you with information to provide a made to measure sizing for the filtration system, in which you find best established for your property.

How we do it 

  • 1. Firstly our team will come in and dig a hole with the machine, 1m square, to a depth depending on the system required for the outlet pipe height below ground level, in which we will then dig a 300mm below that.
  • 2. The hole will be filled with water and left to soak through and seep away overnight. 
  • 3. The next day, our engineers will then re-fill the hole to and observe the time, in seconds, for the water to seep away from being 75% full to 25%, (the depth of 150mm). 
  • 4. The engineers will then calculate the average time in seconds, in which it takes the water level to drop 1mm. 

The test will be done 3 times, each in their own individual holes to give the best averaged result. And the test must not be taken during abnormal weather conditions such as heavy rain, severe frost or drought as it will give an unfair and incorrect result.
