A 6100 gallon white vertical tank, ten feet across and under twelve feet tall
The Norwesco 6100 gallon vertical liquid storage tank, part number 40659, is a polyethylene tank 119 inches in diameter and 140 inches tall, weighing 1286 lb empty. It is the middle shape of the six thousand class: not as tall as the narrow tanks, not as wide as the low ones, so it goes into more sites than either. It comes with a 3 inch polypropylene female NPT bulkhead fitting as the outlet, supplied with a 2 inch reducer, and a 16 inch threaded vented manway on top. The tank is rated for liquids up to 1.5 specific gravity, which covers water, most liquid fertilizers and many common chemicals; 6100 gallons of water weighs 50874 lb. The service limit is 120 F and Norwesco backs it with a 3 year limited warranty under its 2024 liquid storage catalog. White lets you read the level through the wall in daylight.

Where it goes
At 140 inches tall the manway is reachable from a step ladder and the tank clears most barn and shop ceilings, and at 119 inches across the pad is a ten foot circle. That balance is why this is the size we point people to when they have not yet picked a shape. It serves as a farm water reserve, as irrigation and liquid fertilizer storage, as process water in a shop, and as the reservoir in a private fire system; our fire water reservoir design guide covers that last use and the freeze protection it needs. Rainwater and reuse systems are covered in the industrial water reuse topology guide. Size the pad with the concrete pad sizing guide: full of water the tank carries 50874 lb of liquid on its floor, and the whole floor has to be supported, with no part of it hanging past the edge of the slab or the gravel. The complete buyers guide to this tank goes deeper, and the tank sizing calculator and tank sizing guide settle the volume first.
Openings and fittings
- Outlet. A 3 inch polypropylene female NPT bulkhead fitting, factory installed low in the side wall, with a 2 inch reducer in it. Connect 2 inch as supplied, or remove the reducer for the full 3 inch port. Buy the valve to match the choice you make. Support the valve and the first run of pipe on their own so the fitting carries liquid, not weight.
- Manway. A 16 inch threaded vented manway on top: the fill point, the vent and the way in for cleaning or a float switch.
- Drawing. Norwesco's drawing for this tank is linked under Technical Drawing on this page and gives the outlet height and manway position for your pipe layout.
- Liquid. Water and most liquid fertilizers sit inside the 1.5 specific gravity rating. For heavier liquids Norwesco makes a 1.9 rated version of this shell; tell us what is going in and we will point you to the right one.

Shipping and receiving
The tank ships as oversize freight (Norwesco's freight class is OVS) from the nearest of Norwesco's Griffin, Georgia, Lancaster, Ohio, Owego, New York and Washougal, Washington plants, 119 by 119 by 140 inches and 1287 lb on the truck. It travels on an open trailer, so plan on a forklift, a loader with forks or a crew with straps, 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 tailgate, check the part number against 40659 on the bill of lading, look over the shell for transit damage before you sign, and fill it with water the first time before it carries anything else.
