The Snyder Industries 8750 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank is a crosslinked linear polyethylene (XLPE) vertical storage tank rated to a 1.9 specific gravity, molded in black to shield stored water from UV and algae growth. At 146 inches tall on a 142 x 142 inch footprint, it holds 8,750 gallons in a single upright column, which makes it a workhorse for bulk water storage, fire-water reserves, and high-volume vertical tank installations where floor space is scarce.
Will it work for your site?
Filled with water, this tank carries roughly 72,975 pounds of contents, and its 1.9 specific gravity rating allows a maximum rated contents weight of 138,652 pounds. Those two numbers govern your pad design long before the tank arrives: size the slab to the 138,652-pound rated maximum, not the 72,975-pound water weight, if you ever expect to run anything denser than water. A 142 x 142 inch footprint needs a level, engineered, full-contact base under the entire bottom, so size your slab from the actual weights rather than a rule of thumb. For reservoir and fire-storage duty, our Fire-Water Reservoir Tank Design guide walks through NFPA 22 sizing and freeze protection, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm this 8,750 gallon capacity against your real draw and refill cycle.
Fittings and access
The two spec'd, dimensioned access points are an 18-inch polyethylene threaded and vented fitting and a manway with a 15-inch access opening for inspection and interior work. Beyond those, the drawing callouts show a flange, an S.U.M.O.-style fitting (S.U.M.O.), and a bulkhead (BH) fitting, plus flat fitting reference locations at 2.5 degrees and 92.5 degrees on the tank body. An angle callout alone is a reference position, not a customer-actionable size, so confirm every port's location, elevation, and size against the technical drawing on this page before you plumb the site, since inlet, outlet, and vent placement determine how the tank ties into your system.
Why XLPE, and the mistake to avoid
This is a crosslinked polyethylene (XLPE) tank, not standard HDPE. Crosslinking builds a tougher, more impact- and stress-crack-resistant wall, which is why the tank carries a heavy 1.9 specific gravity rating and stands up to large-volume static loads. The common mistake is treating that 1.9 rating as spare capacity for a heavier liquid. For water storage the tank is sized correctly, but do not assume a black water tank is cleared for a specific chemical: the 18-inch threaded fitting, the bulkhead, and the manway all rely on gasket and seal materials that are not specified here, so verify both the XLPE wall AND each fitting's gasket against your fluid before any non-water service. For the reasoning behind choosing crosslinked over linear polyethylene, see Snyder XLPE vs HDPE: When Crosslinking Matters, and for above-ground pad engineering under a tank this heavy, the Concrete Pad Sizing guide covers the ACI framework.
