The Snyder Industries 6600 Gallon Vertical Storage Tank is a full-size bulk water tank molded in black crosslinked linear polyethylene (XLPE) and rated to a 1.5 specific gravity. That 1.5 rating is the top density rating on this tank, so it holds fluids up to 50% heavier than water without derating, and the XLPE wall brings extra strength over standard polyethylene. It's a workhorse for high-volume water storage, rural fire-water reservoirs, agricultural supply, and industrial process water.
Will it work for your site?
This is a 6,600-gallon vertical storage tank standing 158 inches tall on a 120 x 120 inch footprint (10 feet square). Confirm your slab and overhead clearance before you order - at this height, doorway and low-ceiling installs are out. Filled with water, the contents alone weigh roughly 55,044 lb (about 27.5 tons), while the 1.5 SG rating means the tank body is engineered to carry up to about 82,566 lb (roughly 41 tons) of contents. Size your concrete pad to that rated 1.5-SG load, not just the water weight - the margin is what lets you later store a denser fluid. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks, and if you're still settling on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match volume to demand.
Fittings and access
Per the technical drawing on this page, this tank carries a flange fitting, an 18-inch PE fitting that is both threaded (for plumbing) and vented, and a manway with 15-inch access. The venting matters on a tank this size: rapid fill and draw can pull a vacuum, and the vent path protects the tank from collapse. The 15-inch manway gives you a person-and-equipment entry point for interior inspection and cleaning. Both the flange and the threaded connection need gaskets or bulkhead seals compatible with your stored fluid's chemistry and SG, so confirm gasket material when you spec the fittings. Reference the technical drawing on this page for exact fitting locations and orientations before you plumb the tank, since inlet and outlet placement drives your manifold layout.
A common bulk-water mistake
The height is the thing people underestimate. At 158 inches, a 6,600-gallon vertical tank needs both the vertical clearance to stand it up and a level, engineered base to carry more than 27 tons when full. Order the pad and the crane or forklift capacity to match before delivery day, not after. If this tank is going into a rural or remote fire-protection role, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and cold-climate freeze protection.
