Crumpler Plastic Pipe is a manufacturer of corrugated polyethylene plastic drainage pipe. CPP operates the largest corrugated plastic pipe manufacturing plant under one roof on the eastern seaboard.

CPP was founded to produce the small diameter HDPE corrugated pipes that were replacing the clay tile pipes used in septic lines, house foundations, landscaping and farm field drains. Due to the lighter weights of plastic pipes they quicky gained popularity. Later, chemically inert large diameter culvert pipes for use in storm and wastewater runoff control were added to the product line.
