Percolation tests are required to calculate the drainage rate of the land in your site, this so that the wastewater effluent leaving your septic tank or sewage treatment plant may safely drain away into the soil below. It is vital that this test is carried out so that a percolation / sub-surface drainage field can be correctly sized and installed to deal with the wastewater effluent coming from your homes septic or sewage treatment tank.
Failure to do this will result in an inadequate system providing substandard treatment which will inevitably fail, causing blockages and serious risk to the health and well-being of the inhabitants or anyone within the vicinity of the untreated effluent in and around your home.
