Norwesco, Inc. is North America's leading manufacturer of rotationally molded polyethylene tanks for agricultural, water, closed-top industrial, and below ground septic and cistern applications. Norwesco was founded in 1939 in St. Paul, Minnesota under the name of Northwest Plastics, Inc. The name was changed in 1973 and at that time Norwesco was ranked as one of the oldest and largest plastic processors in the United States.

Over the last ten years, Norwesco has significantly expanded their geographic presence through the addition of manufacturing facilities throughout the United States and Canada. Norwesco currently operates 17 plants and is the third largest rotational molder in North America.

Norwesco is committed to the highest levels of product quality and customer service. 

PLEASE NOTE: Tank availability may vary according to manufacturing location. Tank dimensions and capacities may vary slightly and are subject to change without notice.

VerticalWhite or Blue Vertical Storage Tanks are most frequently used for bulk storage and mobile nursing applications. Norwesco vertical tanks feature tie-down slots, built-in graduated gallon indicators, an offset fill-opening and a self-vented, slosh-proof lid.

 

Vertical WaterBlack and Dark Green Vertical Tanks. These water tanks are manufactured using resins that meet FDA specifications to ensure safe storage of potable water. The black or dark green color limits light penetration which reduces the growth of water-borne algae. These tanks are rated at 8 pounds per gallon, which means that they are for WATER STORAGE ONLY! They should not be used for chemicals, fertilizers or any other product. Where applicable, the tanks will carry the NSF approval.
