Questions and Answers about Saturated Buffers for the Midwest
Download Full Text
The basic components of a saturated buffer are a non-perforated tile outlet pipe, a water control structure, a perforated distribution pipe, and a vegetated buffer (Figure 1). The water control structure is installed along the tile outlet pipe and within the buffer. The distribution pipes are connected to the water control structure and installed within the buffer roughly parallel to the stream at a shallow depth below the ground surface.
