Storm Sewers

Corrugated steel pipe (CSP) has been used successfully in storm sewer applications since the early 1900s. Countless miles of CSP provide reliable service throughout the highway system and in all sizes of cities and municipalities. As the need for cost-effective, durable infrastructure has grown over the years, the corrugated pipe industry has responded. Technological advancements provide more hydraulically efficient profiles and highly durable coatings, such as spiral rib pipe, polymer coatings, aluminized Type 2 steel and 4-oz galvanized. These improvements have dramatically increased the usage of CSP in storm sewer applications.
