The Snyder Industries 4500 Gallon HDPE Vertical Liquid Storage Tank (SKU SII-7420000N45) is a white polyethylene vertical storage tank built for high-volume bulk water and liquid holding. It stands 142 inches (11'10") tall on a 102 x 102-inch square footprint, so plan for roughly an 8.5-by-8.5-foot pad plus clearance to stand it upright. This Snyder vertical tank carries a 1.9 specific-gravity rating and, per its name, is built to the ASTM standard for molded polyethylene tanks (ASTM D1998), the same wall-thickness sizing logic that governs long-term HDPE performance.
Will it work for your site?
Sizing this tank is mostly a weight-and-space question. Filled with water, the contents alone weigh 37,530 lb, and the wall is rated to hold up to 71,307 lb of contents at its 1.9 SG limit. That load has to land on properly engineered support, not bare soil. Before you set it, confirm your pad can carry a full tank — our Tank Sizing Calculator and Tank Sizing Guide help you match this 4500-gallon HDPE storage tank to your daily draw and refill cycle, and the concrete pad sizing guide walks the ACI framework for above-ground polyethylene tanks. Fitting configuration — bulkhead outlets, vents, and gasket material — should be confirmed against the Snyder spec sheet when you request a quote.
Why the 1.9 SG rating matters
The 1.9 specific-gravity rating sits at the top of the common Snyder vertical range, above standard 1.0–1.5 fresh-water tanks. If you are storing only water, you are buying structural headroom: the 71,307 lb max-contents figure is the tangible benefit of that heavier wall. Just remember the SG number describes the wall's structural margin, not chemical compatibility — this is a water and general liquid storage tank, so match the stored liquid to the HDPE resin and confirm service before filling. Our guide on HDPE wall thickness at the vapor-saturated headspace explains why inspections that only check the liquid side miss the real failure zone, and for fire-reserve duty the NFPA 22 reservoir design guide covers sizing and freeze protection.
Freight
This tank ships LTL freight as an oversized upright crate, quoted live to your ZIP from the nearest Snyder plant. West-of-the-Rockies buyers generally ship from Chowchilla, CA, and Midwest and Eastern buyers from Lincoln, NE — the closest shipping point is confirmed at quote. Because the 142-inch height affects offload as well as final siting, plan delivery access ahead of time. Get a rate before you order with our Freight Cost Estimator, or call 866-418-1777 and we'll quote it and confirm the closest plant for you.
