Description
Key Features
Nominal Diameter: 36 in
Section Length: 20 ft (reduces joint count and installation time)
Material: HighDensity Polyethylene (HDPE) corrosionresistant, chemicalresistant, and longlasting for buried use
Dual Wall Construction:
Smooth Interior Wall: Promotes efficient water flow with low hydraulic resistance (Mannings n 0.012)
Corrugated Exterior Wall: Provides structural strength to withstand soil and load pressures
Joint Options:
Bell & Spigot: Many models include rubbergasket bell ends for soiltight or watertight connections
Plain End: Allows field connections with couplers
Hydraulics: Smooth interior enables high flow efficiency, reduces clog potential
Standards: Designed to meet common industry standards such as AASHTO M294, ASTM F2306, and ASTM F2648 (productdependent)

Benefits
HighCapacity Flow: Larger diameter and smooth interior surface move greater water volumes efficiently.
Exceptional Durability: HDPE resists corrosion, abrasion, and environmental degradation for long service life.
Structural Strength: Corrugated exterior walls support soil loads and typical construction backfill.
Quicker Installation: Long 20 lengths reduce joints and handling time compared with shorter pieces.
Versatile Use: Suitable for drainage, storm sewers, culverts, and largescale water management systems.
Typical Applications
Large Stormwater Conveyance: Handling heavy runoff from commercial sites, parking lots, and roadway drainage.
Culverts: Under driveways, roads, or access points needing high capacity flow.
Major Subsurface Drainage Systems: For construction sites, agricultural land, and infrastructure projects.
French Drains or Regional Water Control: Where high capacity subsurface water movement is required.
Erosion Control: Managing drainage across slopes and large landscapes.
