Tank Options  

Norwesco is the leading North American manufacturer of rotationally molded polyethylene tanks. Norwesco was founded in 1939 in St. Paul, Minnesota with the name of Northwest Plastics, Inc. The name was changed around 1973 and was then was ranked as one of the oldest and largest plastic processors in the United States.

Norwesco maintains the highest levels of product quality and customer service. Their objective is to continue to provide these valued traits to the customer to maintain a position as the industry leader in the polyethylene tank market.

PLEASE NOTE: Tank availability may vary. Tank dimensions and capacities may vary slightly and are subject to change without notice. Anti-icing systems are available in specific size tanks—call for details /or quotes.

Elliptical Leg Tanks

This elliptical tank style is designed to provide the largest capacity with the lowest center of gravity, making it the most reliable design available for transporting larger volumes. Norwesco elliptical tanks feature molded-in legs that act as “baffles” to aid in the reduction of sloshing and to provide increased stability in transit.

All Norwesco elliptical leg tanks require full-length bottom support and support band (see tank accessories)*

Horizontal Leg Tanks

Horizontal leg tanks are used primarily for anti-icing applications within the snow industry, Norwesco’s leg tanks feature molded-in legs that act as “baffles” to help to reduce sloshing.

Tank Accessories  

Steel Supports & Accessories for Leg Tanks

Norwesco bands are custom made to support their tanks and are galvanized or powder coated for added corrosion protection. Bands are necessary to ensure that the tank retains its shape and integrity.

High-Density Polyethylene Lids   

The hinged lid is manufactured from a copolymer material for strength, durability, and excellent chemical resistance. Its unique locking tab allows you to easily slip a padlock through it and secures the lid from theft or spills. The lid is interchangeable with a standard 16 in. lid and ring assembly, if you choose to replace your existing lid.

  • Easy open/close - opens a full 180°

  • Comes complete with a baffle vent assembly which allows for adequate venting when bottom filling your tank

  • Unique locking tab

  • All parts of lid may be ordered as repair parts

 

Tank Repair Kits & Tank Accessories

The tank repair kit includes a specially formulated welding wire containing copolymers and adhesives. The wire may be used to repair linear polyethylene. Easy to use and requires 110-volt power.

Polypropylene Bulkhead Fittings/EPDM or Viton Gaskets 

Norwesco’s polypropylene fittings come standard with an EPDM gasket. Viton gaskets are available as an option when EPDM may not be suitable for your application. The 2 inch stainless steel bulkhead fitting comes standard without a gasket.

Containment Basin     

Limit your liability by using a Norwesco polyethylene containment tank. Federal, state, and local agencies are enforcing stringent rules and regulations regarding spills, leaks, and overflows from primary containment tanks. Containment basins and tanks are impact and corrosion resistant and are molded as a one-piece, seamless unit. The 125 cone bottom style is a “Tank In A Tank”; the 140, 250, 360, 500, 600 and 1300 gallon sizes are “basin style”; the 1350 is an open top tank and the 2050 and 2800 “Tank In A Tank” are molded with a dome that can be cut off to enable it to be used as a containment tank
