Norwesco 10,000 Gallon Vertical Liquid Storage Tank in White

Three 10000 gallon records, and one of them weighs very differently

The family is where this record gets interesting, and not in a way any sales sheet would volunteer. Norwesco names two other 10000 gallon verticals against 45400: N-43933, 141 by 141 by 160 inches at 2147 lb, whose name says without fittings, and N-44095, 141 by 141 by 160 inches at 2147 lb. This record is 140 by 140 by 160 inches at 1300 lb. Same volume, the same published height, a diameter one inch smaller, and an empty weight that sits a long way below both of them.

We are not going to explain that gap, because the sheet does not, and inventing a reason for a weight figure is exactly the kind of guess that ends up quoted back at us. What we will say is what it means for you practically: if you are comparing these three rows on anything that depends on shell weight, whether that is the lift, the transport or the specification, do not read one row's figure and assume it covers the others. Ask us to confirm the empty weight against part number 45400 in writing and we will get it from Norwesco. That request costs nothing and settles a number that varies by more than eight hundred pounds across records that look identical on a quote.

The other two rows in the family change the shape outright. N-47933 is 6502 gallons in a 102 by 102 by 196 inch body at 1337 lb: a much narrower circle carried much taller, which is the row for a site short of floor. N-43939 is 12000 gallons at 141 by 141 by 193 inches and 2513 lb, the next step up in the same wide footprint. Settle the volume before the outline with the tank sizing calculator and the tank sizing guide.

The 140 inch record against the 141 inch ones

The row that repays attention is the 6502 gallon one. It weighs close to this record while holding considerably less, in a body barely more than seven feet in diameter and over sixteen feet tall. That is the trade this whole shelf is built around: you can have the volume in a wide low body that eats floor, or in a narrow tall body that eats headroom, and the weight of the shell does not track the gallons in any way that would let you guess. If neither a 140 inch circle nor a 196 inch height works on your site, tell us the two dimensions you actually have and we will bring you the rows that fit them.

Torn between two rows? Call 866-418-1777 with the liquid and the ceiling height, or ask for a quote on both and compare the freight.

One 22 inch opening, and two fields that are blank

The top of this tank is the whole of its documented interface, and the field reads 22" on both the manway line and the lid size line. That is a larger opening than most of this range carries and it is a genuine advantage on a body over thirteen feet tall, because everything that will ever go inside this tank has to pass through that circle: a level float, a suction line, a foot valve, a cleaning head, a camera. Nothing in that opening's description mentions a vent, and on a tank this size the air path is worth settling deliberately rather than assuming; ask us what arrangement is available for 45400 before you specify a cover, and we will answer from Norwesco rather than from a neighbouring record.

Below the opening the record goes quiet. The outlet field is empty and the inlet field is empty, which means nothing about the plumbing is described anywhere on this sheet: not a size, not a thread, not a position, not a count. That is what the record says, and we are not going to improve on it with a bulkhead figure borrowed from a sibling. It is a short conversation to have with us against the part number before you order, and it is the conversation that decides how the tank gets connected.

The rest of the interface data in one place: a 1.9 specific gravity figure given as a maximum of 15.87 pounds per gallon, 158460 lb of maximum contents against 83400 lb of water at 8.34 pounds per gallon, a 120 F / 48 C ceiling, and no warranty term published. The install specific for a 140 inch circle holding up to 158460 lb: the surface under it is the single most consequential thing about the installation, it has to be flat and in full contact across the entire footprint, and it has to be designed against the maximum contents figure rather than the water figure. Our comparison of saddle, cradle and concrete pad support for large verticals is the piece to read before anyone pours anything.

10,000 gallons at the higher grade figure

Everything published on this record: 10000 gallons, white high density linear polyethylene, 140 inches in diameter, 160 inches tall, 1300 lb empty and 1300 lb shipping, shipping dimensions of 160 by 140 by 140 inches, a 22" manway and a 22" lid size, blank outlet and inlet fields, a 1.9 specific gravity figure given as a maximum of 15.87 pounds per gallon, 83400 lb of water at 8.34 pounds per gallon, 158460 lb of maximum contents, a 120 F / 48 C ceiling, no warranty term, one plant, and an oversize move with no code published. No application field, no contents field.

The grade figure is the field that should decide whether this record is the right one, because 1.9 is the higher of the two grades Norwesco publishes across its vertical range, and at ten thousand gallons the difference between a shell specified for water and one specified for something denser is not a rounding. For background on how vessels on this shelf get sized and arranged, our guides to the smaller rows are worth the time even when your number is much larger: the 2000 gallon natural white buyer's guide, the 500 gallon guide on the same pattern, and the reservoir design and cold climate article for remote sites.

1300 lb from Hanford on a 160 inch crate line

One plant releases this tank, Hanford, California, and the ships-from field is blank, so there is no second origin to weigh and the lane starts on the west coast wherever you are. The move is oversize on both the ship mode and the freight class field, where the class originally read 500 before the served spec replaced it, and the crate line reads 160 long by 140 wide by 140 high at 1300 lb. That is a shape more than thirteen feet in its longest axis and nearly twelve feet in the other two, which makes it an equipment job at both ends of the lane.

The receiving check that belongs to this record is about the opening, because the opening is all the record documents. Before the driver leaves, confirm that the 22 inch cover is actually with the tank, either fitted or travelling separately with the paperwork, and that the threads or the sealing face on it are clean. A large cover that went missing somewhere in transit is trivially easy to overlook on a delivery this size and impossible to improvise afterwards, and on a tank with no other documented opening it is not an accessory, it is the way in.

Get a real figure for your ZIP from the freight cost estimator; the listed price is before freight. Mark the pad height and the compass orientation of the opening on the site drawing the day it is set, while a tape and a person who cares are both still on site. The first fill is the only cheap time to find a problem, so do it in daylight with someone watching the base.
