Norwesco is North America’s leading manufacturer of proprietary 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 years we have significantly expanded our geographic presence through the addition of facilities throughout the United States and Canada. We currently operate 14 plants and are the third largest rotational molder in North America

We attribute our success to our commitment to the highest levels of product quality and customer service. Our objective is to continue to provide these valued attributes to our customers and thus maintain our position as the industry leader in the polyethylene tank market

Let us help – Whether you are hauling or storing, we have the right tank for you!

The Horizontal Leg Tank

This round storage tank has low, compact design that includes that addition of molded in legs for transportation. This has allowed the tank to be stored in the back of pickup trucks, trailers, tractors, and even around your facility. Round horizontal tanks are typically used for the storage of agricultural products that can include spray fluids, water, fertilizers, pesticides, herbicides, and more. They are even food grade!

This horizontal round storage tank is constructed from one seamless piece of linear polyethylene and is designed to store and transport your materials in non-DOT regulated applications. With UV stabilization, this horizontal storage tank can be stored outdoors without fear of damage due to light or other weather elements.

Our large black vertical tanks:

Norwesco water tanks are manufactured using resins that meet FDA specifications to ensure safe storage of potable water. The black 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! These should not be used for chemicals, fertilizers or any other product. The tanks carry NSF approval.

Vertical White Storage Tanks:

Vertical storage tanks are used for industrial, agricultural, and commercial chemical storage purposes. Liquids that can be stored in these tanks are Water, Calcium Chloride, DEF, Ethyl Alcohol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Biodiesel, Fertilizer, Phosphoric Acid, Polymers, Sodium Hydroxide, Sodium Hypochlorite, Sulfuric Acid, Urea, Brine, Agricultural Chemicals, Industrial Chemicals and many more.
