The Snyder Industries 4500 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a crosslinked-polyethylene vertical storage tank built for high-density bulk water and heavy-liquid duty. It is a wide-body vertical: 143 inches across the base and 91 inches tall, holding 4,500 gallons molded in Natural White. That squat, large-diameter stance matters for planning, so picture a broad tank rather than a tall slim one when you lay out the pad. The crosslinked linear polyethylene (XLPE) shell carries a 1.9 specific-gravity rating, the heavy-duty ceiling of this vertical storage line.
Will this tank work for your site?
Filled with water at a specific gravity of 1.0, the tank carries about 37,530 pounds of contents; at its full 1.9 SG rating it is engineered for a structural ceiling near 71,307 pounds. In water service you are nowhere near that limit, so the 1.9 XLPE rating is real headroom for heavier liquids down the road, not something water duty consumes. The technical drawing on this page shows the fitting layout: a flange for a bulkhead or outlet connection, an 18-inch PE threaded/vented top fitting for fill and venting, and a manway with 15-inch access for interior entry, inspection, and cleaning. Mating gaskets, bulkhead hardware, and vent fittings are sized to those specific ports, so confirm them at order. If you are still deciding on capacity, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a footprint.
Why crosslinked (XLPE) is the no-compromise pick
Crosslinking bonds the polyethylene chains so the wall resists stress cracking and impact better than single-wall HDPE, and it is what supports the 1.9 SG rating on a tank this size. Against a lighter HDPE alternative, this is the heavy-duty ceiling of the line rather than a middle option. Our guide on Snyder XLPE vs HDPE walks through when the crosslinked wall earns its keep, and for rural reservoir sizing the fire-water reservoir design guide covers NFPA 22 discipline and freeze protection for cold sites.
The mistake to avoid
The common miss on a 4,500-gallon vertical is the foundation. This is a flat-bottom tank that needs a level, fully supporting pad rated for the loaded weight and spanning the full 143-inch base. Pouring a pad that only accounts for water weight, or one that does not span the whole footprint, leaves the wall unsupported and invites long-term stress. Our concrete pad sizing guide lays out the ACI 360R-10 framework for getting the base right.
This tank ships LTL from the Snyder plant in Chowchilla, CA, with freight quoted live to your ZIP. Even empty, a 143-inch-diameter XLPE vertical is a large piece that needs a forklift or crane and clear, roughly 12-foot-wide access to offload, so confirm your delivery site and equipment when you request a number.
