New internal structures are comparable to that of CMP, but manufactured with more durable material. Fish and other aquatic organisms now can migrate more easily through their physical environment but with a pipe constructed of HDPE, offering a much longer service life. The interior profiles act as “roughness elements” that decrease the flow velocity and allow for some silt and streambed material to collect inside. Additionally, Snap-Tite can install available baffles to solve depth and velocity problems within a culvert during flow extremes.

​

In low flow situations, most baffles act as weirs to create small pools of standing water. As the flow increases, the water rises up over the baffles. The baffles help decrease flow velocity while creating resting areas for fish to use during high-velocity water flow occurrences. PRS can help you determine the most cost-effective solution for your culvert project.
