The Snyder Industries 3000 Gallon ASTM Black Heavy Duty Vertical Storage Tank (SKU 8160000N51) is a polyethylene vertical storage tank built for high-density liquids. It carries a 1.9 specific gravity rating, which is the number that matters most here: the shell is engineered to hold contents up to 1.9 times the density of water. That rating is why this tank shows a full-water weight near 25,020 lb but a maximum rated contents weight of roughly 47,538 lb. Water fills only a fraction of what the wall can structurally carry, so you have real headroom for heavier solutions. Treat 1.9 as the structural ceiling, not a fill target, and leave freeboard; because that rating already covers essentially every common heavier-than-water solution, there is no step-up model to chase for high-density service.
Will it work for your site?
The tank holds 3,000 gallons in a black polyethylene body, standing 127 inches tall on a 90 x 90 inch footprint. That vertical shape puts a large volume on a compact 90-inch square pad, which suits sites where floor space is tighter than headroom. Run your load through the Tank Sizing Calculator and review the Tank Sizing Guide so the pad is matched to the full 47,538 lb rated figure, not just water. The tank arrives empty and light for offload, but the concrete pad and any anchoring must be founded on that loaded weight; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for exactly this load.
Fittings and access
Per the technical drawing on this page, this vertical tank is configured with a flange, an 18-inch vented polyethylene threaded lid, and a manway with 15-inch access for interior reach. The vented lid is the fill and breathing point, which matters on a 3,000-gallon water tank to prevent vacuum on rapid drawdown. Some gallonage marks may be removed where fittings are placed, so confirm your fitting layout against the drawing before ordering. The drawing does not list gasket or outlet thread material, so confirm gasket compatibility (EPDM, Viton, and the like) and thread size with your plumbing by calling 866-418-1777. The black wall resists UV and light penetration, a practical choice for outdoor storage and for keeping algae growth down.
Freight and ordering
This vertical storage tank ships LTL freight from Snyder's plant in Marked Tree, Arkansas, and freight is quoted live to your ZIP rather than included in the list price. Get an exact number with the Freight Cost Estimator or call 866-418-1777 to lock in delivery. If you are building toward a fire-water reservoir or a water-reuse train, our references on rural fire-water reservoir design and industrial water reuse tank topology help you place this tank in the larger system.
