The Snyder Industries 850 Gallon HDPE Vertical Liquid Storage Tank is a 117-inch-tall white polyethylene vessel built on a 48 x 48 inch footprint and rated to a 1.9 specific gravity, so it carries genuinely heavy liquids inside its 850-gallon volume. It ships with ASTM certification and is the kind of vertical storage tank operators reach for when they need liquid storage capacity that fits a compact pad without sprawling out sideways.
Will this 850-gallon vertical tank work for your site?
Start with the load math before you pour a slab or set a stand. Filled with water, this tank weighs roughly 7,089 lb, and at its full 1.9 specific gravity rating it can hold contents weighing up to 13,469 lb. That difference is the whole point: the foundation has to carry whatever you actually store, not just water. A 48 x 48 inch footprint at 117.29 inches tall is a tall, narrow column, so a level, full-diameter concrete pad and protection from wind loading on an empty tank are both worth planning for. Treat the 850 gallons as nominal, not fully usable - thermal expansion and freeboard mean your real draw-down sits below nameplate, so run your numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you commit to this size.
The 1.9 specific gravity rating - and the mistake to avoid
The most common error on a vertical HDPE tank like this is matching the wrong specific gravity to the stored liquid. This tank is rated for a 1.9 specific gravity, well above water's 1.0, so for general water and liquid storage you have ample structural margin. Two things to watch. First, the headspace: HDPE wall thickness is engineered per ASTM D1998, and the vapor-saturated zone near the top is where premature failures actually originate, not the liquid-wetted side most people inspect - our guide on HDPE tank wall thickness and ASTM D1998 sizing logic walks through why that matters. Second, the connection: at 13,469 lb of contents and 117 inches of liquid column, the outlet fitting and its gasket are the weak point, not the wall, so they must be matched to the stored liquid's chemistry and head pressure. Reference the technical drawing on this page for fitting and dimension detail, and see the 850 gallon vertical liquid storage tank buyer's guide for a full spec walkthrough.
Single-wall storage, double-wall containment, and fire-water reserve
This is a white single-wall tank, which means zero secondary containment. For straight water and benign liquid storage at this 1.9 SG margin that is exactly right. If you are eyeing more aggressive 1.9-SG contents and need spill protection, the double-wall route is the upgrade to weigh - our Snyder Captor double-wall freeboard guide covers how containment and freeboard change the volume you can actually use. An 850-gallon vertical footprint is also a practical building block for rural and remote fire-water reserves where pad space is tight; if that is your application, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
