8400 Gallon Blue Heavy Duty Vertical Liquid Storage Tank

Where it goes

This is bulk storage for a fertilizer retailer, a utility's treatment chemical reserve, a plant's process water or a large fire reserve. The height is the first thing to check: at 188 inches the tank is taller than most pole barn eaves, so it usually stands outdoors or under a high canopy, and the crane needs room to set it upright. The pad carries up to 133106 lb of contents plus the tank on a 119 inch circle; it must be flat, continuous and level with nothing under the base but the pad. For a fire reserve, read our note on fire water reservoir design for rural and remote sites. If the tank will hold a chemical with a vapour, our piece on tank wall thickness at the vapour saturated headspace explains why the heavy duty wall matters above the liquid line, which is where tall tanks are inspected least. The 8400 gallon vertical tank buyers guide covers this size in detail; the tank sizing calculator and tank sizing guide settle whether one 8400 or two smaller tanks suit the turnover.

What goes in it

Water, liquid fertilizer and the treatment and process chemicals that polyethylene handles, with the 1.9 rating covering the dense blends and brines a standard tank is not built for. Keep the contents under 120 F. Light blue keeps most of the light out of stored water and lets you see a faint level line in daylight. If you are not sure a chemical belongs in polyethylene, tell us the name and the concentration before you order.

Openings and fittings

1. Outlet. A 3 inch polypropylene female NPT bulkhead fitting low in the side wall, with a 2 inch reducer in the box. Keep 3 inch for pump suction or a fast gravity draw; reduce to 2 inch where the plumbing is already that size. Support the valve and the first length of pipe on their own so the wall carries liquid, not hardware.
2. Manway. A 16 inch threaded vented manway on top: fill point, vent and inspection opening. Keep it threaded down so the tank breathes through the vent, not the opening.
3. Extra fittings. A second outlet, a sight gauge port or a side fill fitting can go on the same order; tell us before it ships.
4. Drawing. Norwesco's drawing for this tank is linked under Technical Drawing on this page and gives the exact outlet and manway positions.

For water and fertilizer only, the standard 1.5 rating costs less: the 8400 gallon black vertical tank 42060B or the 8400 gallon black vertical tank 44395B. One size down at the heavy duty rating is the 7800 gallon black heavy duty vertical tank; one size up is the 9000 gallon black vertical tank. The swatches above the price switch between the versions of this tank.

Shipping and receiving

At 119 by 119 by 188 inches and 1956 lb this tank ships as an oversize load from Norwesco's plant in Hanford, California. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, and on a long lane it is worth checking before you decide between this and a tank built nearer to you. Have a forklift with long forks or a crane ready. At the tailgate, check the part number against 42062 on the bill of lading, look over the fitting and the base for transit damage, and fill with water the first time so a problem shows up with something harmless in the tank.
