A septic drain field, a septic tank, and associated piping compose a septic system. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals (and surface runoff) from reaching the wastewater distributed within those trenches.

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. [1] The results of a percolation test are required to design a septic system properly.

The leaching process in a salty soil to be reclaimed is illustrated in the leaching curves of figure 1, derived from data of the Chacupe pilot area, Peru. [2] It shows the soil salinity in terms of electrical conductivity (EC) of the soil solution with respect its initial value (ECi) as a function of amount of water percolating through the soil.
