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.
Orangeburg pipe was made of wood pulp sealed with liquified coal tar pitch in inside diameters from 2 inches to 18 inches, with a perforated version for leach fields. . Joints were made of the same material, and, because of the residual stickiness of the coal tar, were sealed without adh

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.
Tile drainage is a form of agricultural drainage system that removes excess sub-surface water from fields to allow sufficient air space within the soil, proper cultivation, and access by heavy machinery to tend and harvest crops.
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure , crop planting, type and application rates of fertilizers , and other factors are taken into account to avoid excessive nutrient loss.
Clearfield Township is located in eastern Butler County, along the Armstrong County border. It contains the unincorporated communities of Coyleville and Fenelton. U.S. Route 422 passes through the township, leading east to Kittanning and west to Butler.
