The Snyder Industries 7900 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank (SKU 7370000N42) is a crosslinked linear polyethylene vertical tank built for high-volume bulk water and fire-water storage, with the wall strength to carry heavier fluids when you need it. It holds 7,900 gallons in a Natural White shell that stands 177 inches tall on a 120 x 120 inch footprint, so confirm pad size and overhead clearance before delivery. The 1.9 specific-gravity rating is what separates this XLPE tank from a standard water-only vertical, and it gives you headroom for liquids denser than water.
Will it work for your site
Filled with water, the tank and contents reach roughly 65,886 lb; at the full 1.9 SG rating the maximum rated contents weight is about 125,183 lb. Those are the loads your foundation has to carry, so size the concrete pad and any anchoring for the rated figure at your actual liquid density, not the water figure. Fittings on this tank, per the technical drawing on this page, include a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access for entry, cleaning, and inspection. The flange bolt circle and gasket have to match the pipe or valve you supply, and the 18-inch PE-threaded fitting is the primary vented fill and draw port, so confirm thread type and elevation against the drawing before ordering flanges, gaskets, or bulkhead adapters. On a tank this size, keep that vent unobstructed during high-rate transfer to prevent a vacuum pulling on the shell. The crosslinked (XLPE) wall also delivers more impact and environmental-stress-crack resistance than a comparable HDPE tank.
The mistake to avoid
The most common error on a vertical storage tank this large is treating the 1.9 SG rating as free capacity. The wall is engineered for a liquid up to 1.9 times the density of water, but freeboard for thermal expansion means the real usable volume sits below the nameplate 7,900 gallons. Work the numbers with the Tank Sizing Calculator and Tank Sizing Guide, and read the Snyder Captor freeboard sizing guide for the ASTM D1998 method behind that number. If crosslinking versus standard polyethylene matters for your duty, the Snyder XLPE vs HDPE guide and the concrete pad sizing framework cover the engineering, and rural fire-protection projects should start with the fire-water reservoir design guide. If your liquid is dense or regulated enough to need secondary containment, look at a Snyder Captor double-wall configuration instead.
