What is an Absorption Field commonly made of?

An absorption field is primarily made up of a series of trenches designed to distribute effluent from a septic system into the surrounding soil. This setup allows for the natural treatment of wastewater through the soil, where microorganisms break down harmful pathogens and organic material. The trenches are filled with gravel or rock, which helps drain the effluent away from the septic tank while providing the necessary surface area for effective absorption and treatment.

The system's design is crucial for ensuring adequate aeration and permeability, allowing the liquid to percolate into the soil effectively. By using a series of trenches instead of a single large field, the absorption capacity is increased, promoting better effluent dispersal and minimizing the risk of saturation or pooling.

A series of tanks and filtration systems might be components of the broader septic system, but they do not make up the absorption field itself. A single large field would not provide the efficiency and effectiveness seen with a series of trenches, leading to potential issues with treatment and absorption.
