Closed Top Rectangular Tanks

American Tank Company’s rectangular closed top tanks are designed for the safe, reliable storage and transport of potable water, gray water, agricultural products, industrial chemicals and much more. Available in a wide variety of shapes and sizes, we offer the most extensive line of these hard to find polyethylene receptacles.

Rotomolded to be seamless, one-piece, watertight vessels, our closed top tanks will not leak, chip, rust or corrode. All of them are manufactured to meet FDA requirements for food and water collection. These tanks are not, however, designed for fuel storage.

• Carefully measure the area where you plan to install your tank. Since these tanks are rectangular, keep in mind they may be used in any position, though if placed up on edge, they will need bracing and supporting. Accordingly, don’t worry about the specifics (length, width and height) – just take three measurements to the closest 1/8^th inch. Plan for additional space when fittings and/or fill lids are required.
• If relevant, confirm the tank size you have determined will provide adequate capacity in terms of gallons. Use of our Tank Capacity Calculator will make this task quick and easy. At American Tank Company we have rectangular closed top tanks that range from 3 gallons to 260 gallons;
• Consider what you will be storing in the tank. Polyethylene tanks are designed to safely contain virtually anything but fuel. However, there are exceptions to every rule. If you will be storing an obscure industrial or agricultural chemical please confirm the tank’s compatibility with an American Tank Company expert. If polyethylene is not appropriate for your situation, these talented individuals can provide a recommendation for your particular need;
• Remember that our closed tops tanks are exactly that – closed top. This means there are no predetermined access holes. If you want to fill and empty the tank, which we assume you do, you will want to select fittings and accessories that are appropriate for your project. To see our entire selection of tank fittings, caps and lids, check out our Accessories page. 
• Once you have selected the fittings that are necessary to complete your project, fill out a Rectangular Tank Order Form. Your Sales Representative will provide you with the form you need. Please note a minimum of two coordinates for each fitting, which will allow us to determine precisely where you want the center of the fittings to lay. Also remember to indicate what size fittings you require.

In addition, please do keep in mind that all American Tank Company rectangular closed top tanks are normally supplied in natural white. Black is available if specifically requested. American Tank Company supports the manufacturer’s 1-year limited warranty, dependent on the chemical compatibility of the tank’s intended content with the tank and tank fitting materials. Order online or call American Tank Company today at 877-655-1100 to order your rectangular closed top tank.

Due to the nature of the rotational molding process, dimensions may vary from what is published and shown on the referenced drawings.

During the delivery process, tanks can pass between several docks and trucks on their way from the factory to the customer. Though not a guarantee, tank wrap “helps” to protect the tanks from getting scuffed and dirty. The best way to avoid cosmetic damage is to set up a will call at the factory and personally handle the tanks yourself.
