The Snyder Industries 6200-gallon vertical liquid storage tank is a White HDPE vessel built for large-scale water and liquid storage, standing 140 inches tall on a 120 x 120 inch footprint - a 10-foot square pad and roughly 11.7 feet of overhead and door clearance to plan into your site and access before the LTL truck arrives. Snyder rates it to a specific gravity of 1.9, well above a standard 1.5-SG water tank, which is the real reason to choose this vessel: it gives you headroom to store dense liquids beyond plain water now or to repurpose the same tank for a denser service later without re-buying. Filled with water it holds about 51,708 pounds of contents; at its maximum rated specific gravity the contents weight climbs to roughly 98,245 pounds, which is the number your foundation, pad, and rigging plan have to account for. If you are still confirming whether 6,200 gallons is the right working volume once freeboard is allowed, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit.
How this vertical storage tank works
This vertical storage tank has an 18-inch PE threaded manway for access and inspection. The technical drawing on this page shows the fitting layout: a flange connection plus eight flat fitting pads at 45-degree typical spacing, which gives you defined locations for outlets, fill lines, vents, and level instrumentation rather than forcing field cuts into the sidewall. Use those engineered fitting flats and the flange for your plumbing - they are where the wall is built to accept penetrations. Connections at the flange and the eight 45-degree fitting flats must be made with bulkhead fittings and gaskets, not field-cut holes, and those gaskets and hardware need to be rated for the liquid you are storing. Because this is a tall vertical tank, confirm your inlet and outlet elevations against the drawing dimensions so your pump and gravity-feed runs line up with the actual fitting positions before delivery.
Specific gravity and the mistake to avoid
The most common error on a tank this large is under-planning for weight. The 1.9 specific-gravity rating tells you the resin and wall thickness will handle heavy liquids, but the pad, anchoring, and freeboard still have to be sized to the real contents weight at your liquid's density, not water. The other quiet failure point is sealing: the HDPE wall is broadly compatible across many liquids, but the gaskets and seals at every penetration are the chemical-compatibility weak link, so if you are storing anything denser than water, confirm the gasket elastomer is compatible with that liquid. For above-ground polyethylene installations of this size, walk through our guide on concrete pad sizing under the ACI 360R-10 framework, and if you want the engineering behind wall thickness and freeboard, see the breakdown of HDPE wall thickness and ASTM D1998 sizing logic. This is a single-wall tank; if your denser-than-water service needs secondary containment, the Snyder Captor double-wall freeboard guide walks through that path, and for fire-water and reservoir duty the rural fire-water reservoir sizing guide covers NFPA 22 discipline and freeze protection.
Freight and ordering
This Snyder vertical HDPE storage tank ships by LTL freight from the Snyder plant in Marked Tree, Arkansas, with the rate quoted live to your ZIP code. A vessel this tall and heavy needs an unloading plan in place before the truck arrives, so confirm your equipment and site access ahead of time. Get an exact freight estimate through our Freight Cost Estimator, or call us at 866-418-1777 and we will quote the freight and walk you through delivery on this 6200-gallon vertical storage tank.
