Advanced Drainage Systems, Inc.
A maker of plastic pipe and drainage systems that carry stormwater and wastewater away from roads, homes, and farms, selling brands like N-12, StormTech, and Infiltrator. Founded in 1966 by two engineers who helped turn plastic pipe into an everyday alternative to concrete, it is now headquartered in Hilliard, Ohio. Its pipes wear a signature green stripe, the standard color marking buried sewer and drain lines so excavators can spot them.
