Those wondering 'what is a percolation test' are likely to be in the process of investigating whether they can put in a soakaway or a septic tank. 

Soakaways in particular are growing in popularity as they help drain land and gardens naturally and can be added to a garden or underneath a driveway and easily covered over so you wouldn't know it was there.
