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.

Common uses for our Liquid Storage Tanks include the storage of fertilizer solutions, agricultural chemicals, water, liquid feeds and plant foods. All of our tanks are rugged, corrosion resistant and lightweight with no seams, welds or joints to leak or rust.

Norwesco‘s polyethylene septic tanks are designed for durability and quick, easy installation. The septic tanks are manufactured by means of the rotational molding process, which produces a one-piece, seamless, watertight tank. Polyethylene is unaffected by soil chemicals and by the chemicals and gases present in sewage, so Norwesco septic tanks will not rust or corrode and require no additional coatings as other tanks do.

Norwesco septic tanks come equipped with manhole covers and detailed installation procedures. The 750, 1000, 1250 and 1500 gallon sizes are available in both one and two compartment configurations.
