    A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin.

This allows much greater flexibility in the placement of the leach field, as well as cutting the required size of the leach field by as much as half. [1]

  9. Water table - Wikipedia

    en.wikipedia.org/wiki/Water_table

    A water table close to the surface affects excavation, drainage, foundations, wells and leach fields (in areas without municipal water and sanitation), and more. When excavation occurs near enough to the water table to reach its capillary action, groundwater must be removed during construction.
