Snyder Industries 6600 Gallon ASTM Black Heavy Duty Vertical Storage Tank

The Snyder Industries 6600 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a Chowchilla-built polyethylene vertical storage tank for large-volume water and dense-liquid holding, standing 158 inches tall on a 120 x 120 inch square footprint. It is rated to the maximum 1.9 specific gravity in Snyder's heavy-duty band, the number that separates this build from a standard water tank and lets it hold liquids substantially heavier than water without exceeding the shell's design limits.

Will this tank work for your site?

Start with the weight, because a 6600-gallon vertical tank is a structural decision as much as a storage one. Filled with plain water it carries roughly 55,044 pounds of contents, and at its full 1.9 SG rating it is engineered for up to 104,584 pounds of liquid. Spread that maximum load across the 120 x 120 inch (14,400 square inch) base and the pad sees about 1,046 pounds per square foot at full 1.9-SG service. That figure drives the foundation: the pad has to be sized for it and the soil under the pad has to carry it. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide, and for the foundation read our guide on concrete pad sizing for above-ground polyethylene tanks so the ACI framework matches this footprint and load.

Fittings and access

The tank is configured with a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for interior inspection and cleaning. Treat the vented feature as the overfill and vacuum-relief path, not just another port: on a sealed vertical tank this size, a fast fill or draw-down needs that vent open and unobstructed so the shell never sees pressure or vacuum it was not built to take. Do not valve it shut. And because this is 1.9-SG service with contents heavier and often more aggressive than water, confirm the manway gasket and flange bolt-gasket material are compatible with your specific liquid before commissioning. Verify the fitting layout and elevations against the technical drawing on this page before you plumb the inlet, outlet, and overflow, since those positions set your pump and gravity-feed geometry.

Freight

This black vertical storage tank ships by LTL freight from the Snyder plant in Chowchilla, California, which is the only named ship point for this SKU. At 158 inches tall it is an oversized load, so freight is quoted live to your ZIP rather than bundled into the list price. West Coast buyers benefit from the short haul; if you are farther east, know that CA is the sole origin and LTL will weigh heavily on freight cost, so price it early with the Freight Cost Estimator or call 866-418-1777.
