Snyder Industries 6900 Gallon Plastic Vertical Liquid Storage Tank With Fitting

Twenty-nine tons of water on a ten foot circle

Full of water, the 7140000C137 puts 57,546 pounds on a 120 inch circle, and a rotationally molded floor bears on the whole pad, so the pad is what matters: an engineered slab in full contact under the entire floor, per the concrete pad sizing guide, screeded flat, with no pipe trench or drain crossing under it. The empty tank is strapped against wind, and the straps go slack once it is full. The first fill is the acceptance test; the hydrostatic test methodology guide covers the fill discipline, the settlement check and the hold time. The tank sizing calculator tells you whether 6,900 gallons covers the draw, and the tank sizing guide covers days of supply.

Snyder's 6,000 to 7,900 gallon verticals

The C37-BLK and C26-BLK are the black 6,900s in this shell, 150 pounds heavier, for water in full sun. The 7000000C26 and 7000000C137 hold 6,000 gallons on this same base at 132 inches, the first with the 1.9 wall, and the 7370000N52 stands 7,900 gallons on this base at 177 inches in the 1.9 grade.

Connections

• Outlet: 3 inch, at the base, installed; a flexible connector between the bulkhead and hard pipe, an expansion joint, and the valve supported off the slab.
• Access: 18 inch manway, 153 inches up, reached from a platform.
• Service limit: 120 F / 48 C.

A 3 inch outlet feeds a fire pump's suction or drains the tank by gravity in minutes, so the valve is opened with the receiving line already connected. A tank this size moves a great deal of air as it fills and empties, so the vent is sized for the pump-out and fill rates and screened. Fit a sender read at ground level so nobody climbs for a number. If winters freeze, wrap or drain the outlet valve and the first pipe run; at this volume the body freezes slowly and from the top down.

What it holds in practice

Well storage for a farm or a small community, irrigation water, brine and fertilizer solution at the 1.5 rating, a fire reserve of the kind the fire-water reservoir design guide describes, where the 3 inch outlet counts, 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.

Getting it to the pad

At 120 inches across and 153 inches long on the deck the 7140000C137 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 forklift with long forks sets 1,300 pounds on the slab. Strap it, fill it to the manway once, hold it, and check the outlet fitting before it goes to work. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
