Environmental Drain Services Ltd can conduct simple pre-purchase surveys of existing septic tanks to determine the effectiveness of the system. This survey is a visual inspection of the foul system to highlight any potential problems.
If required, the survey can include a pressure test to determine the water tightness of the drains.
We can conduct percolation tests to establish the drainage rate of the subsoil. This is an essential test when sizing a soakaway for any drainage system draining to ground via a soakaway.
