A 6500 gallon black heavy duty vertical tank for fertilizer and chemical storage
The Norwesco 6500 gallon black heavy duty vertical storage tank, part number 42973, is a rotomolded polyethylene tank 120 inches in diameter and 147 inches tall, weighing 1506 lb empty. The heavy duty wall is rated for liquids up to 1.9 specific gravity, 1.9 times the weight of water, which is what liquid fertilizers and most concentrated chemicals that polyethylene handles call for. For scale, 6500 gallons of water weighs 54210 lb and a 1.9 liquid about 103000 lb. The outlet is a 3 inch polypropylene female NPT bulkhead fitting with a 2 inch reducer, and the top opening is a 16 inch threaded vented manway. The resin is FDA compliant per Norwesco, Norwesco lists its water tanks under NSF/ANSI 61 (the listing names no models), the service limit is 120 F, and the heavy duty tank carries Norwesco's 3 year warranty. Black blocks light, which protects light sensitive products and keeps algae out of water.

A mid-size bulk tank for heavy liquids
Sixty-five hundred gallons is the size an ag retailer keeps one product in, a blender keeps a base solution in, or a treatment plant keeps a month of a treatment chemical in. The 1.9 rating is what separates this tank from the standard duty 6500 gallon tanks linked below: the bottom of the wall carries the full weight of the column, and a 1.5 tank filled with a heavier liquid is overstressed exactly there. At 120 inches across and 147 inches tall it is a compact tank for the volume, which helps inside a containment berm or a building. The pad carries the whole load on a 120 inch circle; our pad sizing framework for poly tanks covers the slab. If the tank is a fire reserve, read the reservoir design write-up for remote sites; if it sits in a reuse system, the reuse storage topology article shows where it goes. Confirm the volume with the tank sizing calculator and the tank sizing guide.
Openings and fittings
- Outlet. A 3 inch polypropylene female NPT bulkhead fitting low in the side wall, shipped with a 2 inch reducer in it. Pull the reducer for 3 inch pipe and fast transfer; leave it in for a 2 inch valve. Support the valve and the first pipe run independently of the tank wall.
- Manway. A 16 inch threaded vented manway on top for the fill line, a level sensor and inspection access. Keep the vent clear so the tank breathes as the level moves.
- Chemical fit. Polyethylene suits most fertilizers and many chemicals, not all of them. Tell us what goes in and we check it against the material before the order ships.
- Drawing. Norwesco's drawing for 42973, linked under Technical Drawing on this page, gives the outlet height and the manway position.

Shipping and receiving
The tank ships LTL at freight class 300 from Norwesco's Fairfield, Texas plant, 120 by 120 by 147 inches and 1506 lb, on a flatbed. Plan for a forklift with long forks, a telehandler or a crane at the site and a clear path to the pad. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. At the site, check the part number against 42973 on the bill of lading, inspect the wall and the outlet fitting before the driver leaves, and make the first fill water so any problem shows with something harmless in the tank.
