Snyder Industries 15000 Gallon Plastic Vertical Liquid Storage Tank

Sixty-two tons of water on a twelve foot circle

Full of water, the 5370000C37 puts 125,100 pounds on a 142 inch circle, and a rotationally molded floor bears on the whole pad, so the pad is what matters: an engineered slab bearing under every inch of the floor, per the concrete pad sizing guide, screeded flat, with no pipe trench or drain crossing under it. An empty tank gets strapped, because 234 inches of empty polyethylene is a sail, and the straps go slack once it is full. The 15,000 gallon vertical tank buyers guide walks through the competing shapes at this volume; the tank sizing calculator tells you whether 15,000 gallons covers the draw, and the tank sizing guide covers days of supply.

Grades on the 142 x 234 inch tank, and the sizes beside it

The C34 is the general-grade tank in this shell, the N43 is this same 1.5 wall with ASTM certification for a job that needs the paper, and the C26 is the 1.9 chemical wall, all at the same weight. The 3030100C26 holds the same 15,000 gallons on a 165 inch base 50 inches shorter, the 5350000C34 is the 12,500 gallon step down 36 inches shorter, and the 5380000C126 is the 16,500 gallon step up at 257 inches.

Where the pipe goes

• Outlet: specify the bulkhead fitting for the liquid when ordering; a flexible connector at the bulkhead, an expansion joint in the run, and a valve on its own support off the slab. Order a large outlet if the tank is a fire reserve.
• Access: 18 inch threaded, vented manway, 234 inches up, reached from a fixed platform with a rail.
• Service limit: 120 F / 48 C.

A tank this big breathes hard as it fills, empties and warms, so size the vent to the pump-out and fill rates, screen it, and do not rely on the manway default. Fit a sender read at ground level so nobody climbs for a number. In a cold climate the outlet valve and the first run of pipe are insulated or drained; at this volume the body freezes slowly and from the top down.

The work it does

Community water storage, a fire reserve of the kind the fire-water reservoir design guide describes, irrigation storage on a large property, brine, fertilizer solution or coagulant as delivered at the 1.5 rating, and the storage stage of a reuse system for roof water and condensate, per the industrial water reuse tank topology article. One liquid per tank, labeled.

Freight, in plain terms

At 142 inches across and 234 inches long on the deck the 5370000C37 is oversize freight (NMFC 156600) on a flatbed at a lane rate, with an escort on most routes; the freight cost estimator prices the lane to your ZIP; the figure listed here is before freight. A crane sets 4,400 pounds upright on the slab. Fill it to the manway once, hold it, check the outlet fitting, and keep a screen on the vent. Save the pallet; a tank that ever has to move again is easier to move on it.
