What is another term for a leach field?

A leach field, also known as a drain field, is a crucial component of a septic system designed to disperse effluent (the liquid waste) that has been treated in the septic tank into the surrounding soil. The primary function of the leach field is to allow this effluent to percolate through the soil, where microorganisms naturally break down and filter out harmful pathogens and nutrients.

The term "drain field" accurately reflects its purpose: it serves as the area where water drains from the septic system into the earth. This process is essential for the proper functioning of the septic system and maintaining sanitary conditions.

In the context of the other terms: a seepage area may imply a broader concept of water infiltration but does not specifically denote a septic system component. An effluent pond is a different system entirely, where treated wastewater is collected in a pond rather than being dispersed into the soil. Lastly, a wastewater tank refers to the septic tank itself, which holds raw sewage and is not synonymous with the dispersal system. Thus, "drain field" is the most fitting and accepted term for the function and context of a leach field.
