Snyder Industries 6500 Gallon Plastic Vertical Liquid Storage Tank in White

Pad, wind, reach

Full, the 32421 loads a 120 inch circle to 81,315 pounds at the rating: an engineered slab in full contact under the whole floor, level enough that 152 inches of tank stands plumb. Empty, 1,412 pounds with that side area is a sail, so it is strapped or ballasted before the first storm. The manway is 152 inches up, so instrumentation is a hydrostatic sender at the outlet or radar on the lid, never a routine climb. Look up the density of the liquid at the concentration you buy; under 1.5, this is the right wall. The tank sizing calculator and the tank sizing guide settle the volume against the delivery interval, and the day tanks that usually stand beside a bulk tank are covered in the 2,000 gallon vertical tank buyers guide.

Two walls on the 120 x 152 inch shell

The 32425 is this shell with 243 more pounds of wall and the 1.9 rating for concentrated chemicals. The 7140000N40 is the same volume an inch taller with a conventional bottom outlet, for the pad that gives clearance under the fitting. The 8220000C34 is 12 inches shorter for 300 fewer gallons, and the 5300400N40 is the heaviest wall on this base at 1,900 pounds.

Still deciding between these? Freight to your ZIP often settles it; the wider tanks ship differently. Or call 866-418-1777 and we will walk the table with you.

Bulkheads and lid

• Outlet: 3 inch polypropylene female NPT bulkhead fitting with a 2 inch reducer siphon tube to the floor; a flanged transition, an expansion joint, and a valve supported off the slab. A siphon outlet needs a pump or a prime; it does not gravity-drain below the fitting.
• Access: 20 inch threaded, vented manway; size the vent for a tanker's unload rate, and fill through a dip tube to the floor.
• Service limit: 120 F / 48 C.

Keep the vent clear so a fast draw cannot pull a vacuum on the wall, prove the siphon draws to the floor on the water test, and re-check the outlet nut after the first full fill; twelve and a half feet of head is real pressure at the fitting.

Day-to-day duty

Liquid fertilizer and brine at a co-op that takes full tanker loads, dilute treatment chemicals at a plant with a containment basin, and bulk water where a heavier wall is wanted outdoors; with water in it, a fire reserve sized under NFPA 22 as the fire-water reservoir design guide describes. In a freezing climate a solution expands against a wall not designed for ice; house the tank or keep it above freezing.

From the plant to your site

At 120 inches across and 152 inches long on the deck the 32421 is oversize freight (NMFC 156600) on a flatbed at a lane rate; the freight cost estimator prices it for your ZIP, and the listed price is before freight. A crane or a large telehandler sets 1,412 pounds on the slab. Strap it, water-test in stages with a hold, drain through the siphon to prove it, and check the fitting before the product goes in. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
