SOLUTION
The project was originally designed with box culverts and reinforced concrete pipe (RCP) for stormwater conveyance. Advanced Drainage Systems (ADS) successfully converted the design to HP Storm polypropylene pipe, which offered a lightweight alternative ease handling and speed up installation.
HP Storm pipe in diameters 18”–48” was installed to collect and route stormwater into a 60” HP Storm main. Several runs of the 60” pipe replaced what would otherwise have required a double-barrel 72” RCP system. The mains ultimately conveyed stormwater to the site’s drainage ditch.
The contractor, S. Thomas Construction, installed 4,860’ of 60-inch HP Storm pipe in under two weeks, demonstrating the efficiency gains made possible by the lighter, more manageable polypropylene system.
PRODUCT DESCRIPTIONS
HP Storm is a high-performance polypropylene pipe for gravity-flow storm drainage applications. HP Storm is the perfect choice with premium joint performance and increased pipe stiffness. HP Storm couples advanced polypropylene resin technology with a proven, dual-wall profile design for superior performance and durability. The smooth interior wall offers additional strength as well as superior flow. HP Storm has an extended bell that adds an additional factor of safety within each joint. This innovative product meets or exceeds typical standards for pipe stiffness and joint integrity and meets ASTM F2881 and AASHTO M330 for the respective diameters. HP Storm pipe is approved for use by the Army Corps of Engineers, FAA, and AREMA.
