Snyder Industries 1900 Gallon ASTM XLPE Black Vertical Storage Tank

Chowchilla loads it, and the West Coast lane is the short one

Origin decides more of what this tank costs to land than any other line on the sheet. The 1780200N46 is molded at Chowchilla, California and ships from California at class 300, which means a buyer in the Central Valley, on the coast, or anywhere in the intermountain West is paying for a short lane on a tank that measures 72 inches across and 119 inches long on the deck. That footprint matters to the carrier: a 72 inch circle rides inside a trailer rather than as an oversize load, so this is a tank that moves on ordinary equipment, gets set with a forklift or a small crane, and does not need a permit conversation before it can be booked. Buyers east of the Rockies should price the lane before they fall in love with the volume, because a light tank on a long haul pays for air. Run your ZIP through the freight cost estimator and compare; the listed price is before freight in every case. Once it is on site the ground takes over. A rotationally molded floor bears on its own floor and nothing else, so 15,846 pounds of water, or 23,769 pounds at the rating the sheet gives, all goes down through that 72 inch circle. Pour the slab 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. Then strap it. Just under ten feet of empty black shell on a six foot base is narrow enough to walk in a gust, so bands to structure or anchors in the slab go on the day it lands and get checked after the first storm and again at the end of the first summer, because black polyethylene in the sun grows a little every day and the strap that was tight in spring is loose in August. Check 1,900 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.

Four walls in the 1780200 mold, and the 1,600 and 2,000 beside them

Buy this molding when the liquid is light sensitive and no denser than the 1.5 figure on this sheet, and when you would rather not carry the heavier wall's weight on a freight bill. Everything in the top four rows comes out of the same 72 by 119 inch mold at the same volume, listed separately, each rated as its own sheet says. The two heavy duty grades in that shell are listed at 520 pounds, and on a liquid that never tests the wall that extra poundage is wall you pay to ship and never use. The N40 matches this tank at 445 pounds in the natural wall, so the black resin is the whole reason to take this page over that one. Below the shell, the SII-32118 puts 1,600 gallons on an 86 inch base at 71 inches tall, which is the answer when the ceiling stops low and the floor is wide; above it, the 5050000C26 holds 2,000 gallons on a 90 inch base at 88 inches in the heavy duty wall.

The manway sits just under ten feet up

• Access height first, because it is what the install has to solve: the 18 inch threaded, vented manway is at the top of a 119 inch shell. That is above head height and above a step ladder's safe reach, so plan a fixed ladder or a short platform with a rail, and land a permanent fill connection at the manway rather than have a driver hold a hose ten feet up in the dark.
• Outlet as listed: the sheet lists the outlet as one manway/lid 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.
• 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.
• Hardware as listed: two flange lines. No inlet is given on this sheet.
• Service limit: 140 F / 60 C. Warranty: 3 year. Rating: specific gravity 1.5 as the sheet gives it.

Everything on a tank whose only listed opening is at the top has to be designed around that fact. A submersible or a suction line dropped through the manway keeps the shell undrilled, which is the cleanest answer on a black tank with 23,769 pounds of rated contents behind the wall, and it moves every maintenance item to where a person can reach it. If a bottom draw is what the process needs, that is a conversation at order, not a field drill: a hole cut into a rotationally molded wall by someone standing on a pad is the fastest way to turn a 3 year warranty into an argument. Whichever way the liquid leaves, the first valve rides on its own support off the pad and never hangs on the tank wall, and a flexible connector sits between the tank and any hard pipe so thermal movement and pump vibration stay out of the shell. A black wall passes no light into the liquid and takes the ultraviolet that ages a pale one, which is the point outdoors; what it costs you is the sight of the level, so a level device belongs in the install budget rather than next year's.

Light sensitive liquids at tanker scale on a California pad

Sodium hypochlorite at a small water or wastewater plant is the classic load for a black wall at this rating: light degrades it, density does not test the tank, and a plant dosing daily wants most of a delivery in one vessel. Around it sit a co-op with a fertilizer solution that has to stay dark, a food or beverage plant with a cleaning chemical on an outdoor pad, and a grower with a crop input that spoils in sunlight. Where site rules call for a second wall, containment costs usable volume, and the Captor double wall freeboard guide works out what a contained tank actually gives you at this size. Water is well inside the rating, but a fire reserve is a different design problem with its own sizing discipline, set out in the fire water reservoir design guide. Where a plant is banding reclaimed streams by quality before they are reused, the industrial water reuse tank topology article shows where a tank this size belongs in the train.

Class 300 from California, 445 pounds on the forks

Freight leaves Chowchilla, California at class 300 as the sheet lists it, on a 72 by 119 inch footprint that rides as ordinary freight, and the freight cost estimator prices the lane to your ZIP with the listed price before freight. At 445 pounds empty this is a one machine unload: a forklift with long forks or a small crane, straps under the body, never a sling through the manway, and the tank set on its finished pad rather than shuffled across a yard. Before any chemical goes in, fill it with water to the manway, let it stand, and walk the pad edge and the base of the wall looking for movement or a weep; then drain it, dry it, and put the straps on. Write the part number and the commissioning date on the maintenance log the same day, because the number on the log is the only thing that tells the next person which wall rating is standing in front of them. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
