ABSTRACT:
The present invention may be assembled for use in conveying fluids flowing on terrain. A conduit may have two elongated side walls and a bottom connector formed in an approximate V cross section shape. The two elongated side walls may have an upper flange with an edge element that may have an expanded diameter relative to the upper flange thickness. A side panel may have a length that is approximately the same as the two elongated side walls. The side panel may have a groove in each longitudinal edge for attachment to the edge element. The side panel may be attached to a terrain ground structure.
