The Snyder Industries 6500 Gallon Black Heavy Duty Vertical Storage Tank is built for serious bulk water duty: 6,500 gallons of polyethylene storage standing 145 inches tall on a 120-inch by 120-inch footprint. It carries a 1.9 specific gravity rating, which means the tank wall is engineered for contents far heavier than plain water - so an operator who later moves to a denser liquid has built-in headroom instead of having to re-tank. Buy the 1.9 rating now and you avoid re-buying later.
Will this tank work for my site?
Start with the load math, because at this size it governs everything. Full of water, the contents alone weigh roughly 54,210 pounds, and the 1.9 specific gravity rating corresponds to roughly 103,000 pounds of contents at maximum density. That tells you two things: your foundation has to be designed for the full water weight plus the tank itself, and you have substantial headroom if you ever store a heavier solution. The 120 x 120-inch square footprint is what your pad must support uniformly - a flat, level, fully bearing surface is not optional at this tonnage. To match this vertical storage tank to your demand and refill cycle, run the Tank Sizing Calculator and review the Tank Sizing Guide before you commit. If you are pouring the slab, our walkthrough on concrete pad sizing for above-ground polyethylene tanks covers the ACI framework that applies directly to a black vertical tank of this weight.
Common uses and the mistake to avoid
A black 6500 gallon vertical tank like this is a workhorse for bulk water storage, agricultural supply, industrial process water, and rural fire-protection reserves. The most frequent mistake at this scale is treating the 1.9 specific gravity rating as a license to skip your own engineering: the rating describes what the tank wall can handle, but your pad, anchoring, and plumbing still have to be sized for your actual contents and site conditions. If this is a fire reserve, size the usable volume deliberately - our guide to fire-water reservoir tank design walks through NFPA 22 sizing discipline and freeze protection for cold-climate installs. For greywater, rainwater, or HVAC condensate programs, the industrial water reuse tank topology guide shows where a tank this size fits in a banded storage train. If you need secondary containment for anything beyond plain water, our Snyder Captor double-wall freeboard sizing guide covers the double-wall containment option and how to size its usable volume.
Specifications, fittings, and connection integrity
This is a vertical storage tank: 6,500 gallon capacity, 145 inches tall, 120 x 120-inch base footprint, black polyethylene, rated to 1.9 specific gravity. For exact fitting locations, sizes, and outlet placement, see the technical drawing on this page - it is the authority for where your fill, outlet, and vent connections land, and outlet and fitting sizes are confirmed per-unit against that drawing before shipment. Before you order, call 866-418-1777 and have us verify the bottom outlet size against your specific pump or manifold, so you are not reworking plumbing on a full tank. One more compatibility note: at 54,000-plus pounds of static head, the usual failure point is not the polyethylene wall but the bulkhead fittings and gasket seals at the outlet - confirm bulkhead fitting and gasket material with us for any liquid other than ambient water.
This ~54,000 lb-when-full, 120 x 120-inch, 12-foot-tall tank ships LTL freight from the Snyder manufacturing plant in Chowchilla, CA, and freight is quoted live to your ZIP - not bundled into the list price. The long-haul distance from a single California plant materially drives the quote, so run your delivery point through our Freight Cost Estimator before you budget, or call 866-418-1777 and we will quote it with you. At this weight and footprint, confirm you have forklift or crane access and a prepared, level pad ready at the delivery site before scheduling.
