A 2100 gallon heavy duty vertical tank rated to 1.9 specific gravity
The Norwesco 2100 gallon blue heavy duty vertical liquid storage tank, part number 40241, is a light blue high density linear polyethylene tank 87 inches in diameter and 89 inches tall, weighing 349 lb empty. Heavy duty means the wall is built for liquids up to 1.9 specific gravity: a full load of water weighs 17514 lb, and a full load at the 1.9 limit weighs 33277 lb, which is the figure the tank is designed around and the reason to buy it over the standard 1.5 tank of the same size. It comes with a 2 inch polypropylene female NPT bulkhead fitting as the outlet and a 16 inch threaded vented manway on top. The service limit is 120 F. Norwesco's 2024 liquid storage catalog gives it a 3 year limited full replacement warranty. Light blue marks the heavy duty version; the same tank also comes in black heavy duty, linked below.

Where it goes
This is a bulk tank for a fertilizer plant, an ag retailer, a water treatment building or an industrial yard: 87 inches across and 89 inches tall, so it stands in a normal height building with the manway a step above head height. The pad under it has to be flat, level and continuous across the whole circle, and at over sixteen tons full at the 1.9 limit the pad is engineering, not landscaping; our guide to concrete pad sizing for above ground polyethylene tanks sets out the method. The complete buyer's guide to the 2100 gallon 87 by 89 inch vertical walks through siting this footprint in detail. Outdoors, a liquid that grows algae or degrades in light belongs in the black version.
What goes in it
Liquid fertilizer, brine, and the water treatment and industrial chemicals that polyethylene handles are the loads this rating is for; water is fine too, and where the job is a water reserve our note on fire water reservoirs for rural sites is relevant. Check every chemical against our chemical compatibility guide before it goes in, and keep the contents under 120 F. The 1.9 rating is a weight limit, 15.87 lb per gallon, not a chemical approval; a liquid can be light enough and still wrong for polyethylene. Norwesco's resin status letter and certificate documents are on file; tell us what the job requires and we will send what applies to this tank. For the volume itself, use the tank sizing calculator and the tank sizing guide.
Openings and fittings
- Outlet. A 2 inch polypropylene female NPT bulkhead fitting, factory installed low in the side wall. Your valve threads straight into it. Support the valve and the first length of pipe on their own so the fitting carries liquid, not hardware, and put a flexible connector between tank and pipe: a full tank settles and grows a little, and rigid pipe fights it.
- Manway. A 16 inch threaded vented manway on top, wide enough to fill from a hose, drop a float or level sensor in, and get a hand and a brush inside.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet height and position and the manway location.

Shipping and receiving
The tank ships LTL from the nearest of Norwesco's plants, 87 by 87 by 89 inches and 349 lb, upright on a flatbed or a trailer with the width for it. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, and for a job that needs paperwork you can. Have a forklift and a clear path ready. At the tailgate, check the part number against 40241 on the bill of lading, look at the whole wall, the bottom edge and the outlet fitting for transit damage, set it on its pad the same day, and fill it with water the first time before it carries anything heavier.
