The Pipe Blog

When designing a Culvert or Storm Sewer the designer needs to take into consideration the type of end treatments that are available in the marketplace. The Federal Highway Administration (FHWA-HIF-12-026 Hydraulic Design Series Number 5) recommends that all pipe 48” in diameter and greater needs to have proper end protection. This selection is one of the major decisions as the Engineer of Record that you must make. Both prefabricated and constructed in place installations are available options for the designer.
