Description
Product Overview 15 × 30 DualWall HDPE Drainage Pipe
A 15 × 30 dualwall drainage pipe is a heavyduty, highdensity polyethylene (HDPE) pipe designed to carry stormwater and groundwater efficiently in residential, commercial, and infrastructure drainage applications. Dualwall pipe combines a smooth interior for efficient water flow with a corrugated exterior for structural strength under soil loads. HDPE material resists corrosion, abrasion, and chemical attack over time, and the lightweight nature of the pipe makes it easier to transport and install compared with concrete or metal alternatives. Dualwall pipe is available in solid (for conveyance) or perforated (for infiltration/French drain) versions and typically uses bellandspigot connections with gaskets for soiltight or watertight performance depending on the job requirements.
Common examples of 15 × 30 products include:
15 x 30 HDPE dualwall drainage pipe (plain end or bell end)
15 x 30 ADS N12 (storm drainage)
15 x 30 plastic corrugated culvert pipe
Key Features
Nominal Diameter: 15 in
Length: 30 ft per stick (fewer joints, faster install)
Material: HighDensity Polyethylene (HDPE) corrosionresistant, durable
Wall Construction: Dual wall smooth interior for improved flow, corrugated exterior for strength
Joint/Connection Options:
Bell & Spigot (soiltight or watertight) with gasket
Plain End for couplers
Hydraulic Efficiency: Smooth interior surface yields low resistance to flow (Mannings n 0.012)
Standards: Typical compliance with AASHTO M294, ASTM F2306, and ASTM F2648 (varies by manufacturer)

Benefits
Efficient water conveyance: Smooth interior maximizes hydraulic performance.
Durable construction: HDPE resists corrosion, abrasion, and environmental degradation.
Structural strength: Corrugated exterior wall provides strength under soil loads without heavy bedding.
Reduced labor: 30 stick length means fewer joints and faster installation.
Versatile: Available in solid or perforated versions depending on whether water needs to be carried off or infiltrated locally.
Typical Applications
Stormwater drainage runs on residential or commercial sites
French drain systems under landscaping or adjacent to foundations
Yard/field drainage and slope water control
Roadside or driveway culverts
Subsurface water management under grading
