The Snyder Industries 1900 Gallon HDPE Vertical Liquid Storage Tank is a 147-inch-tall vertical storage tank built from high density linear polyethylene with a 1.9 specific gravity rating, putting it among the most capable density ratings in our vertical tank line for heavy liquids. It stands on a 64 x 64-inch footprint and is built to ASTM D1998, making it a serious choice for fire-water reservoirs, bulk water storage, and dense-liquid service where a thin-walled water-grade tank would not hold up.
Will it work for your application?
Filled with water this tank carries 15,846 pounds of contents, and its 1.9 SG rating lets it hold liquids up to a maximum rated contents weight of 30,107 pounds. That relationship is the point: 30,107 lb over the 15,846 lb full-water figure works out to roughly 1.9 times the density of water at full volume, so you can back-calculate the safe fill level for a fluid heavier than water rather than guessing at margin. The wall thickness is engineered to ASTM D1998 for denser fluids, which is the reason to choose this Snyder vertical over a standard 1.0 or 1.1 SG water tank. The white HDLPE shell measures 147 inches tall by 64 inches in diameter. Use the Tank Sizing Calculator and our Tank Sizing Guide to confirm this 1900-gallon size fits your draw-down and refill cycle before you commit.
Fittings and access
This unit comes configured with a flange fitting, an 18-inch PE threaded and vented port, a flat fitting, and a manway with 15-inch access for inspection and cleanout. Treat the 18-inch threaded/vented port and the manway as access and venting points, not process plumbing — the inlet, outlet, and drain connections, along with thread type and gasket material, are shown on the technical drawing on this page, so confirm those against your discharge plumbing and mating fittings before you order. Reference the technical drawing for exact port locations and elevations so you can lay out your connections correctly. For above-ground installs, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for a base that supports a fully loaded tank. With roughly 30,107 pounds spread over the 64-inch-diameter base (about 2,827 square inches), the ground-bearing load lands near 10.6 lb/in², or about 1,530 psf — a number your engineer can check against your pad or soil before clicking through.
The mistake to avoid
The most common error on a tank like this is treating wall thickness as constant top to bottom and inspecting only at the liquid line. On HDPE storage tanks, the vapor-saturated headspace is often where premature failures originate, and standard liquid-side inspection misses them. Our write-up on HDPE tank wall thickness at the vapor-saturated headspace and the related fire-water reservoir tank design guide cover the ASTM D1998 sizing logic and NFPA 22 discipline that operators should understand before putting this vertical into service.
