The Snyder Industries 7900 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a full-size vertical storage tank built for high-volume water and dense-liquid holding, sized for sites where a smaller tank forces too many refill cycles. Molded from polyethylene in black and carrying a 1.9 specific gravity rating, this Snyder black tank stands 177" tall on a 120" x 120" footprint and holds 7,900 gallons. The 1.9 SG rating is the number to understand first: the wall is engineered to carry contents up to 1.9 times the density of water, so plain water storage (SG 1.0) sits well inside its structural envelope with real headroom to spare.
Will it work for your site?
Filled with water, this tank carries roughly 65,886 lb of contents; at its maximum rated 1.9 SG loading it is engineered for up to 125,183 lb. Those are the in-service loaded numbers your pad and soil have to support — a 120" x 120" footprint concentrates a lot of weight on a 10-foot square, so confirm your foundation before delivery. The fitting set is built for a tank this tall: an 18" PE threaded and vented fitting handles fill and vent airflow as the tank drains and fills, a flange gives you a plumbed connection point, and a manway with 15" access is your interior entry for cleanout and inspection. Check the technical drawing on this page for the exact fitting positions and elevations, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm 7,900 gallons matches your draw-down and refill schedule.
The mistakes worth avoiding
The most common error on a tank this size is under-building the pad. A vertical storage tank of this height and loaded weight needs a level, engineered slab — our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies. The second is treating 7,900 gallons as fully usable: it's the nominal capacity, and real draw-down is less once you account for freeboard. The Snyder freeboard sizing guide (ASTM D1998) shows how to figure the volume you can actually work with. And because the 1.9 SG wall is heavily de-rated for water, the same tank carries brine and denser chemistry up to 1.9 density without stepping up to another model — headroom you already own.
Freight and next steps
This tank ships LTL freight from Snyder's plant in Lincoln, NE — a Midwest ship point that keeps LTL miles down for central-U.S. sites — quoted live to your ZIP, with no flat national rate on a 7,900-gallon vertical tank this size. It ships empty, so the 65,886 lb and 125,183 lb figures above are loaded in-service weights, not shipping weight. If you're sizing this for rural fire-water reserve or a water-reuse train, our fire-water reservoir design guide covers NFPA 22 sizing and the industrial water reuse topology guide shows where a bulk vertical tank fits. Get a freight number in seconds with our Freight Cost Estimator, or call 866-418-1777 with your delivery ZIP and site access details and we'll quote the freight and confirm the fitting layout before your order ships.
