The Snyder Industries 6200 Gallon Vertical Liquid Storage Tank is a white, ASTM-certified vertical tank molded from high density linear polyethylene (HDLPE) for above-ground water and liquid storage. Dimensions are 140 in H x 120 in W x 120 in L, giving a 120 x 120 inch square footprint, and it carries a 1.4 specific gravity rating, real headroom over the 1.0 SG of plain water. If you have been searching for a large HDPE vertical storage tank, this is the size class that anchors a fill station, a bulk water reserve, or a fire-water supply.
Will it work for your site?
At 6200 gallons, plan your pad and plumbing around the loaded weight, not the empty shell. Full of water this tank weighs roughly 51,708 lb, and at its maximum rated contents (1.4 SG) it reaches about 72,391 lb. That load drives your foundation design, so size the slab to the 120 x 120 inch footprint and the contents weight you actually intend to store. The 1.4 SG rating also means this tank is rated for liquids up to 1.4 times the density of water, covering most brines, fertilizer solutions, and many process liquids, not just plain water. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you pour, and use the concrete pad sizing guide to work through the ACI 360R-10 framework and the ACI 318 boundary.
Fittings and access
The technical drawing on this page details the molded fitting layout: a flange, eight flat fitting pads positioned at 45-degree typical spacing, and an 18-inch PE threaded manway for top access. That manway is large enough for inspection and interior cleanout, and because it is threaded there is no separate bolt-ring gasket to source. Fitting placement on a tank this size is molded in, not a field retrofit, so confirm your fill, outlet, and vent locations against those eight pads before you order. The 1.4 SG rating means the wall is engineered with margin, but the wall runs thinnest at the vapor-saturated headspace, where failures tend to start; the guide on HDPE tank wall thickness and ASTM D1998 sizing logic explains why and how to inspect for it.
The mistake to avoid
The common error on a tank this large is treating the empty weight as the planning number. A 6200 gallon vertical tank goes from a manageable shell to over 25 tons once filled, so an undersized or unlevel pad is the failure mode that matters here, not the tank itself. Pour a level, properly sized slab rated for the loaded weight, and verify the footprint and contents load before delivery. If this tank is headed for rural or remote fire protection duty, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
