Percolation Tests

Percolation Testing Services

Subscan’s percolation tests play a vital role in site investigations, catering to the needs of businesses, developers, and contractors. These tests are indispensable components of the planning process for septic tank systems or sewage treatment plant soakaways. By conducting thorough soil percolation tests, we ascertain how quickly the soil absorbs a known volume of water. This data is crucial for ensuring that the selected soil is conducive to proper drainage and that the soakaway is appropriately designed to meet regulatory standards and environmental considerations.

Moreover, beyond determining soil suitability, percolation tests help in sizing the soakaway correctly. Understanding the absorption rate of the soil allows us to calculate the optimal dimensions for the soakaway, ensuring efficient wastewater management and preventing potential issues such as flooding or groundwater contamination.

A percolation test includes:

  • Excavate a hole 1m square and 1m deep
  • Dig the test hole vertically to the proper depth. Remove all loose debris
  • Line with Visqueen
  • Fill the test hole with water
  • Accurately time noting depth at 5, 10 and 30 second increments
  • Carry out the test at least 3 times, with at least 2 trial holes
  • The average figure from the tests is taken
  • Report produced
