Liquid Storage Tanks

Our polyethylene storage tanks range in size from 12 gallons to 15,000 gallons and are manufactured in a variety of shapes and styles. 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 tanks are manufactured using resins that meet FDA specifications to ensure safe storage of potable water, and where applicable, our tanks are also NSF approved. Quality, price, product line and leading edge technology make Norwesco North America's largest manufacturer of rotationally molded tanks.

Vertical Storage Tanks Horizontal Leg Tanks Elliptical Leg Tanks
Vertical Storage Tanks
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.
Horizontal Leg Tanks
With the broadest leg tank line available, Norwesco manufactures a size that will fit your needs. Used primarily for transport and nursing applications, Norwesco’s leg tanks feature molded-in legs that act as “baffles” to reduce sloshing. Please refer to page 5 for support bands.
Elliptical Leg Tanks
This elliptical tank style is designed to provide the greatest capacity with the lowest center of gravity, making it the best design available for transporting larger volumes. Norwesco elliptical tanks feature molded-in legs that act as “baffles” to reduce sloshing and provide increased stability during transport. Norwesco elliptical leg tanks require full length bottom support as well as support bands. Please refer to page 5 for support bands. The 1600 flat bottom requires full length bottom support but does not require bands.
Drainable Leg Tanks Pickup Truck Tanks PCO Tanks
Drainable Leg Tanks
When complete drainage is necessary, these are the tanks of choice. They are designed primarily for use on fertilizer and chemical nurse trailers. All Norwesco drainable tanks require full length bottom support as well as support bands. Please refer below for support bands.
Pickup Truck Tank
Designed to fit full-size, American made pickups, the 325 and 425 sizes have low profiles for better rear vision. They feature fill openings offset to the side of the tank for safety and easy access. A tough circular design adds strength. The 210 gallon tank fits both “mini” pickups and full-size models. Depending on which way the tank is turned, the bottom width can be either 39" or 48".
PCO Tanks
A multi-purpose tank, the PCO is well suited for nursery, agricultural and lawn care applications. These tanks feature self-supporting legs and do not require any saddles or steel supports. Flat spots are molded into both ends to provide mounting areas for agitation equipment.
Flat Bottom Utility Mini Bulk Tanks Elliptical Tanks
Flat Bottom Utility Tanks
The Flat Bottom Utility tank can be used for many applications. It is the perfect choice when looking for a tank to put in the bed of a pickup truck. The tank may be used with or without bands.
Mini Bulk Tanks
Norwesco mini bulk tanks are most frequently used for chemical dispensing. The tanks can be mounted on forklift accessible pads for ease of movement. A 2" polypropylene fitting is installed directly across from the fill-opening.
Elliptical Tanks
Designed for larger volume applicator needs, the Norwesco elliptical tanks feature a low profile design and a low center of gravity for excellent visibility in the field and increased stability when towed. A deep sump permits complete drainage and the tanks feature an 8"or 16" fill-opening. Please refer to information below for steel supports.
Applicator Tanks Inductor Tanks Spot Sprayer Tank
Applicator Tanks
Whether you’re looking for a new or replacement tank, you’ll find it in the Norwesco line. All Norwesco applicator tanks feature a lid which threads directly into the fill-opening of the tank to prevent the sloshing or leaking of tank contents during transport or application.
Inductor Tanks
The inductor tanks are suitable for mixing chemicals when filling a tank.
Spot Sprayer Tanks
The spot sprayers feature threaded inserts on the bottom of the tank for mounting purposes, on one side for wand/gun placement and on the top for a 12 volt pump. Please refer to page 9 for steel supports.
Black or Dark Green Water Tanks Horizontal Box Tank Low Profile Tank
Black or Dark Green
Water Tanks

Our water tanks are manufactured using resins that meet FDA specifications to ensure safe storage of potable water. The black or green color limits light penetration, which reduces the growth of waterborne 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. Please contact your distributor for more specific information regarding NSF approval.
Horizontal Box Tank
The low profile design of this tank makes it ideal for use on trailers or in the back of a truck. The slosh reduction ribs provide excellent structural support. It can also be used as a stationary water storage tank.
Low Profile Tank
The low profile tanks may be used for storage or transport. They are an excellent choice when height limitations are a factor and are the perfect height for putting under your cottage or cabin.
Free Standing Water Tank Containment Basin/Tanks Cone Bottom Tanks
Free Standing Water Tank
These tanks have been specifically designed with residential and commercial applications in mind. The dimensions of the 250, 300 or 400 gallon allow it to fit through a conventional doorway. The design of the freestanding/self-supporting tanks eliminate the need for a steel support frame.
Containment Basins/Tanks
Be kind to the environment and 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. These spills can be hazardous and costly and with that in mind, we have designed our containment basins and tanks to meet your containment needs. Our containment basins and tanks are impact and corrosion resistant and are molded as a one-piece, seamless unit. 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” is molded with a dome that can be cut off to enable it to be used as a containment tank. Required containment capacity may vary depending on application and location.
Cone Bottom Tanks
Norwesco offers a full range of cone bottom tanks designed for a variety of applications. The conical bottoms enable quick and complete drainage. As with all Norwesco tanks, the cone bottom tanks are molded of rugged, high density polyethylene and are both impact and chemical resistant. Please refer below for polyethylene or steel stands.
