    This installation method is by far the most labor-intensive. In addition, material cost is a function of the width of the grate used in the trench. There are three main reasons why this is labor-intensive: the outlet pipe position in the floor, the levelling of the trench grate in the floor, and integration of the waterproofing.

    The primary disadvantage associated with the two stage drainage ditch is the upfront cost of the earthwork necessary to increase the existing channel for the benches to be constructed.

    This system proved to be highly cost-effective. Instead of a system of curbs, sidewalks, and gutters, which would have cost nearly $400,000, the planted drainage swales cost $100,000 to install. [6] This was also much more cost effective than building BMP ponds that could handle 2-, 10-, and 100-year storm events. [6]

    en.wikipedia.org/wiki/Culvert

    Culvert failures can occur for a wide variety of reasons including maintenance, environmental, and installation-related failures, functional or process failures related to capacity and volume causing the erosion of the soil around or under them, and structural or material failures that cause culverts to fail due to collapse or corrosion of the ...
