This Advanced Drainage Systems (ADS) model 4520010 is a 4-inch by 10-foot triple-wall perforated drainage pipe designed for highly efficient water dispersion and management. Constructed from robust high-density polyethylene (HDPE), it features a unique co-extruded three-layer design with smooth inner and outer walls bonded to a corrugated structural core. This engineering gives it superior pipe stiffness and impact resistance when compared to standard PVC or single-wall corrugated alternatives. The pre-drilled holes make it perfect for septic leach fields, foundation footer drains, downspout runoffs, and landscape drainage systems. It comes with integrated bell and spigot ends for seamless, soil-tight connections without requiring glue. This specific item is in used-fair condition, making it a cost-effective choice for residential or light commercial drainage projects
