Snyder Industries 3900 Gallon ASTM XLPE Black Vertical Storage Tank

The plant that buys 3,900 gallons in a narrow footprint

Start with who writes the check. A tank of 3,900 gallons is bought by a water or wastewater plant that wants a full delivery to land in one vessel instead of two, by a co-op that stores liquid feed through a season, and by an industrial plant that doses one chemical steadily and hates splitting a load. The delivery is the reason the shape matters. A tanker pulls onto the pad, the driver runs a hose up to a manway 163 inches off the ground, and he pumps a load that will weigh 32,526 pounds as plain water into a shell only 90 inches across. That is a narrow base carrying a tall column, so the pad is engineered rather than guessed: a rotationally molded floor bears on its own floor and on nothing else, so every pound goes onto that 90 inch circle at a higher bearing pressure than a squat tank of the same volume puts on the same slab. Pour it level and in full contact per the concrete pad sizing guide, inside a berm sized to the tank where the liquid is regulated. Then strap it, because 900 pounds of empty shell standing 163 inches tall is what a gust moves; the sheet lists 4 tie-down lugs for exactly that, and the bands get checked after the first storm and again at the end of the first summer, since 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 pale shell outdoors, and the price of that is that you cannot read the level through it, so a sender belongs in the install rather than in next year's budget. Test 3,900 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 5190000 shell

Buy this wall when the duty is a 1.5 liquid and the money is better spent on the install than on wall you will never load. The 5190000N48 is the heavy-duty wall in the identical 90 x 163 inch shell at 1,200 pounds empty, rated as its own sheet says, and it is the one to take when the liquid is denser than this page allows. The N40 and the N49 are the other two walls in the same shell, each listed at 900 pounds and each rated on its own sheet. Off the shell, the 8190000C26 puts 3,650 gallons on a wider 102 inch base at 126 inches for a site with a low roof, and the 7421100N40 holds 4,000 gallons at 104 inches on a 120 inch circle, which is the squat answer to the same volume when there is floor but no height.

Priming a pump under thirteen feet of head

• Pump: with 163 inches of liquid standing above the floor, this is the best static suction head in the family. Set the transfer pump below the tank floor so gravity keeps it flooded, keep the suction run short and straight, and fit a low-level float so it stops before it draws air. A pump that runs dry on a dense liquid is the failure that takes the seal with it.
• Draw-off: the sheet lists the outlet as 12 and names no bulkhead size, material or thread, so the draw-off is specified at order against the liquid. Whatever it turns out to be, it gets a flexible connector to hard pipe and the first valve carried on its own support off the pad, never hung on the tank wall.
• Access: 18 inch threaded, vented manway, 163 inches up. A platform with a rail for anyone who opens it, a dip tube to the floor for the fill, and a vent run outdoors and sized to the delivery pump on anything that fumes.
• Handling points: the sheet lists 8 lifting lugs, 4 tie-down lugs, ladder lugs and 3 flange lines.
• Service limit: 140 F / 60 C.

The pump is where a tall tank pays you back and where it punishes a lazy install. Thirteen feet of column keeps a flooded suction all the way down to the last few inches, so a plant gets a full 3,900 gallons of working volume rather than a tank it has to stop drawing at half. That same column is head the outlet fitting and the first valve feel every hour of the day, which is why the valve sits on a support and the connector between fitting and pipe flexes. Keep the manway shut between deliveries so vapor stays in and rain stays out, put the name of the one liquid inside on the wall, and give the band of wall above the liquid line a light every time the lid comes off. Where winters freeze, wrap or trace the valve and the first pipe run; the shell itself takes ice from the top down without complaint.

Dark storage for hypochlorite and liquid feed

The loads that land in a black 1.5 wall at this volume are the ones light spoils and density does not test: sodium hypochlorite at a treatment plant, a liquid fertilizer solution at a co-op that stores through a season, and a process chemical that stands outdoors all summer. A fire reserve is a different buy, and the fire-water reservoir design guide explains what that duty asks for that a chemical wall is not sold to do, even though plain water sits well inside this rating. Where a reuse train holds a treatment chemical between its storage stages, the industrial water reuse tank topology article shows where a tank this size belongs in the sequence.

Lincoln, Nebraska to the pad at class 300

The 5190000N46 ships from Lincoln, Nebraska at freight class 300 as the sheet lists it, and at 163 inches long on the deck it rides as a permitted load; the freight cost estimator prices the lane to your ZIP, and the listed price is before freight. A crane or a loader stands 900 pounds up with straps under the body or on the lifting lugs, never through the manway, and the tie-downs go on before the crane leaves the yard. Then fill it with water to the manway once and hold it, watching the pad edge and the draw-off fitting for movement or a weep, and drain and dry it before the real liquid arrives. Write the date of that water test on the manway with a paint marker, because it is the first thing anyone asks about a tank and the last thing anyone remembers. 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.
