Snyder Industries 290 Gallon ASTM Black Heavy Duty Vertical Storage Tank

Five feet tall on a three and a half foot circle

Start with the ceiling, because on this tank the ceiling is the whole argument. At 60 inches the top of the shell sits at chest-and-shoulder height, so it fits under a mezzanine, under a low shed roof, under a pipe rack, and on a truck bed without a permit for height. The lid is reached from the ground by anyone who can see over it, which means nobody schedules a platform to open it. Against that, the base is wide: 42 inches across does not pass a 36 inch doorway, so the route from the dock to the pad gets measured before the tank is ordered, not after it is sitting on the trailer. The pad does the rest of the work. Plain water puts 2,419 pounds inside the shell and the 1.9 rating allows 4,595 pounds, and all of it bears on a 42 inch circle, because a rotationally molded floor carries on the whole floor and on nothing else. Pour the slab to the concrete pad sizing guide, level and in full contact, inside a berm sized to the tank where the liquid is regulated. A short, wide tank is the least wind-sensitive shape in the range, which is exactly why people skip the straps on it; do not. Empty at 80 pounds it will walk across a slab in a gust, so it gets banded to structure or to anchors in the slab the day it lands, and the bands get looked at after the first storm and again at the end of the first summer, because a black wall in the sun grows a little every day. Black passes no light into the liquid and takes the ultraviolet that ages a white shell; it also hides the level, so the gauge is a sender rather than an eye. Whether 290 gallons carries the draw between deliveries is a question for the tank sizing calculator, and the reserve and the warm-weather freeboard come out of the tank sizing guide.

The wide 290 against the tall 290

Everything in the table holds roughly the same liquid; what differs is the shape of the room it wants. The three 1013000 tanks put the same 290 gallons on a 36 inch base and go to 72 inches tall, which is the buy when floor is scarce and headroom is not, and each of them is rated as its own sheet says. The 1011200C26 is narrower still and taller again at 82 inches. This tank is the one to pick when the roof, the rack or the trailer is the limit and the floor is free, and it is also the one to pick when you want the lid at standing height instead of overhead. The 5740100N42 is the other squat option, wider on the floor at 47 inches and heavier empty at 96 pounds.

A lid, not a bulkhead: what the sheet actually gives

• Outlet, first, because it is the field people assume: the sheet gives the outlet as "1 Manway / Lid" and gives no bottom fitting size at all. We print that as it stands rather than guess a bulkhead diameter. Tell us the liquid and the draw-off you need when you order and we confirm what this molding accepts before anything is cut.
• Listed opening: a 10 inch threaded, vented lid at 60 inches. It is the smallest top in this family and it is the one real constraint on the tank, because 10 inches admits a fill hose, a vent line and a level probe comfortably and admits a person not at all. Internal cleaning is done with a wand through the lid, not by entry.
• Fill and vent: land the fill line at the lid on a permanent connection so no driver is holding a hose over the rim, run a dip tube to the floor so the incoming stream does not free-fall and foam, pipe the vent outdoors on anything that fumes, and size the vent to the delivery pump rather than to whatever port is nearest.
• Service limit: 120 F / 48 C. Warranty: 3 year. Rating: specific gravity 1.9 as the sheet gives it.

A 10 inch lid at standing height changes the routine more than the rating does. The tank gets opened easily, which is good for inspection and bad for everything else, so the discipline is to keep it shut and threaded between deliveries and to make each opening deliberate: a light on the band of wall above the liquid line, a look at the threads and the gasket seat, and the date on the log. Put the name of the one liquid on the wall in letters a driver reads from the cab. Where the site freezes, the trace heat and the insulation belong on whatever piping is plumbed at the base and on the first valve, not on the tank body, which takes ice from the top down without harm.

Where a short, wide 290 earns its pad

This is the tank for a low room: a chemical feed cabinet under a mezzanine, a wash-bay makeup tank beside a pressure washer, a nursery feed tank under a greenhouse gutter, a service truck or skid build where anything taller would not ride, and a pump house where the ceiling is a joist and not a roof. It is also the tank people buy in pairs and gang together, because two low tanks on one pad give the same volume as one tall one with none of the strapping argument. Where a site rule or an insurer wants the liquid inside a second wall, the Captor double wall freeboard guide works out how much usable volume a contained vessel really returns at this size. Water at 8.34 pounds per gallon sits far inside the rating, but a private fire reserve is a different specification in a water-rated vessel, which the fire-water reservoir design guide sets out. Where a reuse train needs a small dark holding stage between treatment steps, the industrial water reuse tank topology article shows where a tank this size belongs.

Merced to your dock at class 300

The sheet gives class 300 and 80 pounds shipping weight from Merced, California, which is the only California origin among the tanks around it, so a West Coast dock lands this one on a short lane and an East Coast dock should price it before assuming. At 42 inches across and 60 inches tall it is a cube-rated parcel rather than a heavy one, and the freight cost estimator prices the lane to your ZIP; the listed price is before freight. Eighty pounds comes off the trailer by hand with two people or on a pallet jack, straps under the body and never a sling through the lid, and it goes straight onto the cured pad rather than onto gravel it will have to be dragged off later. Then water: fill it to the lid, hold it, walk the base and the pad edge twice looking for movement or a weep, drain it and let it dry before the working liquid arrives. Keep the pallet it arrived on, because a tank this wide and this light is easier to move again on the pallet than off it. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
