6,200 gallons at the 1.9 rating, 1,678 pounds of black wall out of Marked Tree
The Snyder 8220000N48 is the heavy-duty wall in the 8220000 shell: 6,200 gallons inside a 120 inch circle standing 140 inches tall, 1,678 pounds empty, molded in black crosslinked polyethylene. Its sheet rates that wall for a specific gravity of 1.9, which it reads as 98,245 pounds of maximum contents against 51,708 pounds for plain water at 8.34 pounds per gallon. The listed opening is an 18 inch threaded, vented manway, the sheet lists eight lifting lugs, ladder lugs and one flange line, the service limit is 140 F / 60 C, the warranty is 3 year, and freight is class 300 out of Marked Tree, Arkansas.

The pad carries 98,245 pounds on a ten foot circle
Start at the ground, because on this tank the ground is the whole argument. A rotationally molded floor bears on its own floor and on nothing else, so every pound goes down through a 120 inch circle: 51,708 pounds with plain water in it, and 98,245 pounds if the liquid works the 1.9 rating the sheet gives. That is a bearing pressure a slab poured by rule of thumb will not hold flat, and a pad with one low corner puts the load on that corner. Pour it to the concrete pad sizing guide, level, cured, in full contact under the whole floor, and inside a berm sized to the tank wherever the liquid is regulated. Next the roof line. The shell needs 140 inches of clear height and then room above the manway for a fill line, a vent and a person, so the purlins get measured before the order is cut. Then the wind. Nearly twelve feet of empty shell on a ten foot base is what a gust walks across a pad, so bands to structure or anchors set in the slab go on the day it lands, get looked at after the first storm, and get looked at again at the end of the first summer, because a black wall in the sun grows a little every day and a strap that was tight in April is loose in August. The black is the point outdoors: it passes no light into the liquid and takes the ultraviolet that ages a pale shell. What it costs you is the sight glass, so a level device belongs in the install budget rather than in next year's, and the level gauge selection article sets out which kind survives which service. Check 6,200 gallons against the draw between deliveries in the tank sizing calculator, and take the reserve and the warm-weather freeboard from the tank sizing guide.
Five walls out of the 8220000 mold
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| 8220000N48 (this tank, black, rated 1.9) | 6,200 | 120 x 140 in | 1,678 lb |
| 8220000C34 (black) | 6,200 | 120 x 140 in | 1,350 lb |
| 8220000C37-BLACK (black) | 6,200 | 120 x 140 in | 1,350 lb |
| 8220000N33 (black, rated 1.35) | 6,200 | 120 x 140 in | 1,174 lb |
| 7000000C34 (lower) | 6,000 | 120 x 132 in | 1,050 lb |
| 7140000N33 (taller) | 6,500 | 120 x 153 in | 1,450 lb |
Buy this molding when the liquid is heavier than water and the footprint is already fixed. Everything in the top four rows comes out of the same 120 by 140 inch mold at the same volume, listed separately, each rated as its own sheet says, and the only reason to take this one is the 1.9 figure and the 1,678 pounds of wall behind it. The 8220000N33 is the light end of the same shell at 1,174 pounds and a 1.35 rating, and on rinse water or a feed solution it is the cheaper honest answer. There is also a lighter-rated black tank in this identical shell, listed on its own page with its own rating and its own empty weight, which is the middle choice between the two. Against the neighbours, the 7000000C34 keeps 6,000 gallons at 132 inches for a tighter ceiling, and the 7140000N33 takes 6,500 gallons up to 153 inches where the bay has the height to spare. Crosslinking is the other half of the decision, and the crosslinked against high density polyethylene article explains when it earns its cost.

The outlet field reads 23.3, so the draw-off is set at order
- Outlet, first, because it is the field buyers read as a pipe size: the sheet lists the outlet as 23.3 and gives no bottom fitting diameter, material or thread anywhere on it. We print the field as it stands and guess nothing. Name the liquid and the draw-off arrangement you want at order and we confirm what this molding takes, in what material, with what gasket, before anything is drilled.
- Listed opening: an 18 inch threaded, vented manway at the top of a 140 inch shell. That is overhead work, so a fixed platform with a rail and a gate, and a permanent fill connection landed at the manway rather than a driver holding a hose eleven feet up in the dark.
- Fill and vent: a dip tube run to the floor so the incoming stream does not free-fall the height of the tank and foam the headspace, the vent piped outdoors on anything that fumes, and the vent sized to the delivery pump rather than to whichever port is nearest.
- Handling and hardware as listed: eight lifting lugs, ladder lugs, one flange line.
- Service limit: 140 F / 60 C. Warranty: 3 year. Rating: specific gravity 1.9 as the sheet gives it.
Whatever gets plumbed at the base is carried on its own support off the pad, with a flexible connector between the tank and hard pipe, and nothing rigid is ever bolted straight to the shell. Eleven feet eight inches of standing liquid at 1.9 puts real static pressure on a base fitting, and a rigid run feeds every bit of thermal movement and pump vibration back into the wall. Set a transfer pump below the outlet so gravity keeps it primed, and fit a low-level float so it stops before it draws air. The manway stays threaded shut between deliveries so vapour stays in and rain stays out, the wall carries the name of the one liquid inside in letters a driver reads from the cab, and the band of wall above the liquid line gets a light every time the cover comes off, because the vapour-wetted band ages before the submerged wall does.
Dense liquids a Delta plant buys by the tanker
This is the tank for a liquid that weighs more than water where the pad is already poured and the volume has to stay at 6,200 gallons: a brine or a concentrate at a municipal plant, a dense process solution feeding a dosing skid, a fertilizer solution at a co-op that stores in the open and needs it out of the light. Where a site rule or an insurer wants the liquid inside a second wall, the double wall freeboard sizing guide works out how much usable volume a contained vessel really returns at this size, which is never the number on the label. Plain water at 8.34 pounds per gallon sits far inside this rating, but a private fire reserve is a separate specification in a water-rated vessel, and the fire-water reservoir design guide sets out why.
Marked Tree, Arkansas, class 300, and the first water fill
The sheet gives class 300 and 1,678 pounds shipping weight out of Marked Tree, Arkansas, so a Mid-South dock lands this one on a short lane and everyone else should price it rather than assume it. Put the ZIP into the freight cost estimator before the requisition goes in; the listed price is before freight. A tank 120 inches across and 140 inches long on the deck prices on the space it occupies rather than on the scale. A crane or a loader with long forks stands it up on the lugs and with straps under the body, never a sling through the manway, and it sets down on the cured pad rather than on gravel it will have to be dragged off later. Then water before the working liquid: fill it to the manway, hold it, walk the base and the pad edge twice looking for movement or a weep, drain it and let it dry, on the discipline the hydrostatic test methodology article lays out. Photograph the tank full on its pad the day it is accepted; that photograph is the baseline every later inspection gets compared against. Check the strap tension a week after the first fill; a tank settles a little, and the strap that was tight is loose.
