The Snyder Industries 4500 Gallon ASTM XLPE Vertical Storage Tank (SKU 7000400N40) is a crosslinked-polyethylene bulk-water tank molded in Natural White, the vertical storage tank people reach for when they need serious on-site capacity in a single vessel. It stands 91 inches tall on a roughly 143-inch (about 11.9-foot) diameter circular footprint, and the natural-white wall is translucent enough to read the water line without opening the top. Size your pad and overhead clearance to those dimensions before you order.
The headline spec: 1.5 SG headroom
A full load of water in this tank weighs 37,530 lb. What sets this XLPE tank apart from a standard 1.0-SG water-only tank is its 1.5 specific-gravity rating, which supports contents up to 56,295 lb. That extra margin is the whole point of crosslinked (XLPE) construction here: it is rated for denser contents and higher-stress duty, which matters for fire-reserve, agricultural, and industrial process water where you want a safety margin rather than a tank running at its limit. Use the Tank Sizing Calculator and Tank Sizing Guide to match this capacity to your draw-down and refill cycle.
Fittings and access
Per the technical drawing on this page, this tank is configured with a flange, an 18-inch PE threaded/vented fitting, and a separate manway with 15-inch access for interior inspection and cleaning — two distinct openings, so plan your plumbing around both. The flange and threaded connections need matching gaskets and bulkhead fittings sized to your lines; confirm the gasket material against your service and verify fitting locations on the drawing before you commit to a tie-in. Call 866-418-1777 if you need help confirming placement before the tank ships.
Foundation and planning
A tank this size lives and dies by its foundation, and a crosslinked vessel is unforgiving of a bad pad. Size the concrete for the full 56,295 lb rated weight distributed across the circular base — our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework. If this is a rural fire-protection reservoir, our fire-water reservoir tank design guide covers NFPA 22 sizing and freeze protection; for reuse and aggregation setups, see our industrial water reuse tank topology guide. The mistake to avoid: undersizing the pad or forgetting overhead clearance for the 91-inch height plus fill plumbing.
