The Snyder Industries 9500 Gallon Vertical Storage Tank is a black crosslinked linear polyethylene (XLPE) vertical storage tank built for high-volume water and dense-liquid storage. It measures 120 inches in diameter and 215 inches tall, sits on a 120 x 120 inch square footprint, and holds 9,500 gallons. At full water, expect roughly 79,230 pounds of contents load on the pad. This is a Snyder XLPE storage tank engineered around a 1.5 specific gravity rating, so it carries capability that most standard vertical tanks do not.
Will this tank work for your job?
Two numbers decide whether this tank fits your site: footprint and loaded weight. The 120-inch square footprint and 215-inch height mean you need overhead clearance for the tank plus fill plumbing, and a foundation rated for the load. With water, contents alone reach about 79,230 pounds; at the full 1.5 specific gravity rating, the tank is engineered for contents up to roughly 118,845 pounds. Design the pad to that maximum 118,845-pound figure, not just the water weight — the roughly 39,600-pound spread between the two is exactly the margin a foundation must account for if you ever run a denser fill. Use these figures with the Tank Sizing Calculator and the Tank Sizing Guide to confirm your pad and clearances before you order. Because this is a black-resin tank, it limits light transmission, which helps suppress algae growth in water service.
Fittings and access
Per the technical drawing on this page, this tank comes configured with a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, and two 12 x 24 inch fittings (one flat). Those fittings determine your connection kit: confirm the mating flange gasket, bolt pattern, and fitting thread sizes against the drawing before ordering connections, since the inlet, vent, and manway placements drive your plumbing and gasketing layout. The 15-inch manway access matters for interior inspection and cleaning on a tank this size.
The 1.5 specific gravity rating is the detail to get right
The most common mistake on a large vertical tank is mismatching the specific gravity rating to the liquid. This tank is rated to 1.5 specific gravity — 50 percent denser than water — which is why it carries denser contents than a typical 1.0-rated water tank. That capability comes from the crosslinked polyethylene itself: XLPE's higher stress and impact resistance is what lets Snyder rate this unit for heavier fills instead of water-only density. Water sits at 1.0, so you have ample margin for water storage; if you ever move to a heavier liquid, verify that liquid's specific gravity stays within the 1.5 rating, and account for freeboard and thermal expansion when you set usable versus nominal volume — our Snyder freeboard sizing guide walks through the ASTM D1998 math.
Concrete pad and freeze planning
At this scale the foundation is not optional. Review our guide on concrete pad sizing for above-ground polyethylene tanks before pouring. For rural fire-protection reservoirs, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. If you are aggregating grey-water, rainwater, or condensate, the industrial water reuse topology guide maps the storage train.
