This article and our accompanying septic system location videos explains how to find the leach field or drainfield portion of a septic system. We include sketches and photos that help you learn what to look for, and we describe several methods useful for finding buried drainfield components.

Septic drain fields are also called soil absorption systems or seepage beds. Also see How to Find the Septic Tank.
