Absorption Field

Absorption

An absorption field is an area of sand, gravel or porous dirt which serves as the last stage of the septic system process. Final percolation of the liquid occurs in the field. Many times, the field is elevated and looks like a sand mound. Mound absorbtion fields are used mainly when there is not enough available land to permit sufficient perocolation.

Both sand mounds and absorbtion fields work under the same concept. Clarified liquid waste is dispersed evenly amoung the area by way of a pipe network. The pipes have 3/16" holes around the perimeter to assist in an even distribution throughout the field. The only difference in the two fields other than physical appearance is liquid transport to the field. The sand mounds require a dosing tank so that the effluent can be pumped to the top of the mound. Liquid from a septic tank destined for the adsorbtion fields is gravity fed through a distribution box and into the pipe network leading into the field.
