The Snyder Industries 3900 Gallon ASTM Black Vertical Storage Tank is built for high-volume water storage where footprint discipline matters: it holds 3,900 gallons on a 90-inch by 90-inch square footprint and stands 163 inches tall, so it stacks capacity vertically instead of sprawling across your pad. Molded from black polyethylene with a 1.5 specific gravity rating, this is a serious bulk vertical tank for rainwater harvesting, fire-water reservoir duty, industrial process water, and reuse trains where you need thousands of gallons in a compact plan area.
Will it work for your site?
Filled with water, this tank carries roughly 32,526 pounds of contents, and its 1.5 specific gravity rating means it is engineered to hold up to about 48,789 pounds of contents at maximum rated density. Because it is rated to 1.5 specific gravity, you have real structural headroom over a standard 1.0-rated water tank, so the shell is not running at its limit on plain water. That contents weight is the number that drives your foundation. A tank this size belongs on an engineered, level pad sized to carry the full load without differential settlement — walk through the framework in our concrete pad sizing guide for above-ground polyethylene tanks before you pour. To confirm 3,900 gallons is the right volume for your draw and refill cycle, run the numbers in our Tank Sizing Calculator and read the Tank Sizing Guide.
Fittings and access
This vertical storage tank comes configured with a flange, an 18-inch polyethylene threaded and vented fitting, a manway with 15-inch access, and two S.U.M.O. self-contained fittings — a 10-inch by 12-inch unit and a flat-mount unit. The 15-inch manway access gives you a clear path for inspection, cleaning, and gauge or sensor installation, while the vented fitting handles the air exchange a tank this tall needs during fast fill and draw cycles. Confirm the exact outlet positions, fitting bolt pattern, and gasket spec against the technical drawing on this page before ordering flanged connections, so your plumbing and overflow routing line up before delivery.
Fire-water and reuse duty
The tall, small-footprint geometry makes this a strong fit for private fire-protection storage and for water-reuse aggregation where several streams feed one buffer tank. At 163 inches tall on a 90-by-90-inch base, confirm overhead clearance and a crane or boom offload path before delivery. If you are sizing a reservoir for rural or remote fire protection, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For grey-water, rainwater, and condensate aggregation, the industrial water reuse tank topology guide shows how a tank like this fits a quality-banded storage train.
