A 12000 gallon black heavy duty vertical tank for dense liquids in bulk
The Norwesco 12000 gallon black heavy duty vertical storage tank, part number 43921B, is a polyethylene bulk tank 141 inches in diameter and 193 inches tall, weighing 3303 lb empty. Heavy duty means a thicker wall rated for liquids up to 1.9 specific gravity, so it carries dense fertilizers, brines and chemicals a standard tank cannot; 12000 gallons of water weighs 100080 lb, and the heaviest full load at 1.9 is 190152 lb. It comes with a 3 inch polypropylene female NPT bulkhead fitting as the outlet and a 22 inch threaded vented manway on top. The resin is FDA compliant per Norwesco, Norwesco lists the tank as NSF 61, the service limit is 120 F, and Norwesco backs the heavy duty tank with a 5 year warranty. Black keeps light out of the contents.

Who buys a 12000 gallon heavy duty tank
This is a plant tank: an ag retailer's UAN or liquid fertilizer storage, a chemical distributor, a municipal water or wastewater plant's bulk treatment chemical, a food plant's brine, or an industrial site with a dense process liquid. For plain water or a fire reserve, the standard duty 12000 does the same job with a thinner wall and a 3 year warranty. The tank is just under twelve feet across and sixteen feet tall, so it is an outdoor tank on an engineered slab with a fixed ladder or a platform to reach the manway, and almost always inside secondary containment. Full of water it puts about 50 tons on the pad, and nearly twice that with a liquid at 1.9. Our guide to sizing a concrete pad under an above-ground polyethylene tank covers the framework and where it hands off to a structural engineer.
What goes in it
Liquid fertilizers, brines, many acids and bases, and water. The 1.9 rating is about weight, not chemistry: check the liquid in our chemical compatibility guide before it goes in, and keep the contents under 120 F; polyethylene softens as it warms and the rating assumes that ceiling. For the volume, the tank sizing calculator and tank sizing guide turn a delivery size and a draw rate into gallons.
Openings and fittings
- Outlet. A 3 inch polypropylene female NPT bulkhead fitting, factory installed low in the wall. Put a flexible connector between the tank and any rigid pipe: a tank this size grows measurably as it fills and a rigid line levers on the fitting. Support the valve on its own.
- Manway. A 22 inch threaded vented manway on top. The vent lets air move as the level changes; a transfer pump pulling against a plugged vent can collapse a wall.
- Inlet. No separate inlet is installed. Tell us before the order ships if you want a fill fitting at a set height; on a tank this tall it saves a climb every delivery.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet position relative to the manway for piping layout.
