Product Description

The ADVANCED DRAINAGE SYSTEMS 24850020dw is a 24-inch diameter, 20-foot section of N-12 Dual Wall pipe designed for soil-tight, solid-wall drainage applications. It features a smooth interior wall for optimized hydraulic flow and a corrugated exterior for structural strength. The pipe is manufactured from application-specific high-density polyethylene (HDPE), which delivers superior resistance to corrosion and abrasion. This combination of hydraulic efficiency and durability makes it a proven alternative to reinforced concrete pipe (RCP) and corrugated metal pipe (CMP) in a wide range of drainage installations.

This pipe is suited for residential, commercial, and municipal stormwater and subsurface drainage projects. Its soil-tight, solid-wall construction prevents infiltration and exfiltration, making it appropriate for storm sewer mains, culverts, and detention system piping. Licensed plumbers, civil contractors, and drainage specialists typically install this product in trench applications where soil stability and long service life are priorities.

Key Features

• Smooth interior wall promotes high hydraulic flow efficiency
• Corrugated exterior provides structural rigidity and load resistance
• High-density polyethylene (HDPE) construction resists corrosion and abrasion
• Soil-tight solid wall prevents groundwater infiltration and effluent exfiltration
• Serves as a direct alternative to RCP and CMP in drainage applications
• 20-foot pipe sections reduce joint frequency in long runs

Compatibility

Designed as an OEM-style N-12 dual wall HDPE drainage pipe compatible with standard N-12 fittings, couplers, and soil-tight joining systems in 24-inch diameter configurations.

Installation Notes

Installation should be performed by a qualified contractor or licensed drainage professional in accordance with local codes and ADS installation guidelines. Trench bedding and backfill material must meet the pipe manufacturer specifications for HDPE flexible pipe to ensure proper load distribution. Confirm all fittings and couplings used are rated for soil-tight service before assembly. Always follow applicable ASTM and local municipality requirements for storm sewer and culvert installations.
