Description
Key Features
Nominal Diameter: 30 in
Length: 20 ft per stick (reduces number of joints, speeds up installation)
Material: HighDensity Polyethylene (HDPE) corrosionresistant, chemicalresistant, and durable for buried service
Dual Wall Construction:
Smooth Interior Wall for efficient water flow (low hydraulic resistance)
Corrugated Exterior Wall for structural strength under soil loads
Joint Options:
Bell & Spigot (soiltight or watertight gasket available)
Plain End versions for use with couplers
Hydraulics: Smooth interior yields low Mannings n ( 0.012), providing good flow performance
Standards: Typical compliance with AASHTO M294, ASTM F2306, and ASTM F2648 (varies by manufacturer and joint type)
Installation Ease: Lightweight compared to concrete pipe easier to transport and install on site (fewer joints with 20 lengths)

Benefits
Efficient Flow: Smooth interior helps water move rapidly and reduces clogging risk.
Durability: HDPE resists corrosion, freeze/thaw cycles, abrasion, and chemical exposure.
Structural Strength: Corrugated exterior wall supports soil loads without requiring extensive bedding.
Fewer Joints: 20 ft sections reduce the number of couplings needed versus shorter pipe lengths, reducing labor and potential failure points.
Versatile Applications: Works well in storm sewers, culverts, French drain systems, low spot drainage, and largescale site stormwater conveyance.
Typical Uses
Stormwater Conveyance Systems capturing and redirecting runoff from properties, parking lots, and roads.
Culverts under driveways, roadways, or low access points needing large capacity flow.
Site Drainage managing high water volumes on commercial, industrial, or residential development sites.
French Drain or Subsurface Drainage for large capacity groundwater control.
Erosion Control under slopes or drainage basins where high volumes of water must be managed.
