The Snyder Industries 2000 Gallon XLPE Vertical Liquid Storage Tank (SKU SII-5050300N42) is a cross-linked polyethylene vertical storage tank rated to 1.9 specific gravity, built and shipped from Snyder's Chowchilla, California plant. Measuring 96 inches in diameter and 84 inches tall, it holds 2,000 gallons on a 96.0 x 96.0 inch footprint, so plan your pad to that full square. The XLPE wall and 1.9 SG rating are the reason to choose this tank over a cheaper 1.0 water-only unit: it is qualified for denser chemistries that a standard fresh-water tank cannot legally or safely hold.
Will it work for your site?
Full of water, this vertical storage tank carries 16,680 lb at the base, but its construction is rated for contents up to 31,692 lb — nearly double the water weight — because the 1.9 SG rating exists for liquids denser than water. That rated number, not the water figure, is what you size your pad and foundation against. For a 2,000-gallon vertical, a level, engineered slab is not optional. The fittings shown on the technical drawing on this page are a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access. Match your inlet, outlet, and vent hardware and gasket material to the flange and 18-inch PE threaded fitting before you trench plumbing, and confirm fitting locations and elevations against the drawing — changing a penetration after the fact on a polyethylene tank is not a field repair you want to make. The 15-inch manway access is what lets you inspect the interior, check gaskets and seals, and clean out between products, so verify your gasket material is compatible with the liquid you intend to store.
Sizing it correctly
If you are working out whether 2,000 gallons is the right volume, run your numbers through our Tank Sizing Calculator and the Tank Sizing Guide. Because this is a higher-density tank, density and usable volume both factor into your sizing — our Snyder Captor freeboard sizing guide walks through ASTM D1998 thermal expansion, chemistry, and the real volume you can actually use at a given specific gravity. For vertical tanks in this 1,500-to-10,000-gallon class, atmospheric venting deserves real attention; an undersized or blocked vent is a common and avoidable failure point. Our worked examples in Atmospheric Vent Capacity Calculations for Polyethylene Storage Tanks walk through the API 2000 inbreathing and outbreathing math, and the 18-inch vented fitting on this tank is your starting point for that calculation. If you are weighing wall thickness and long-term durability at the headspace, the HDPE Tank Wall Thickness guide explains the ASTM D1998 sizing logic behind tanks like this one, and rural fire-water buyers should read our Fire-Water Reservoir Tank Design guide for NFPA 22 sizing.
The mistake to avoid
The biggest error on a tank this size is treating the water weight as your design load. The contents weight rating here is 31,692 lb against 16,680 lb of plain water, and the 1.9 SG rating exists precisely for denser liquids. Size your slab, anchoring, and any secondary containment to that rated number. Just as important, do not assume the 18-inch top fitting alone provides adequate venting for fast fill or draw-down — confirm vent capacity against your transfer rate before commissioning.
