Springfield Plastics, Inc. Dual Wall Polyethylene Pipe combines a corrugated outer wall for exceptional strength and a smooth inner wall for outstanding hydraulic characteristics.

The primary use is to convey water for underground non-pressure applications such as storm sewers, highway underdrains, drainage outlets, roadway culverts and farm drainage main lines. Other uses include underground conduits for telephone, electrical, television cable.

DWP has a corrugated outer wall with a smooth inner wall, which gives the pipe superior strength. This allows the DWP to be buried as shallow as 1 foot and as deep as 29 feet with Class III backfill compacted to 90% Standard Proctor Density.
