The Snyder Industries 1200 Gallon Vertical Liquid Storage Tank is a white polyethylene vertical tank standing 57 inches tall on an 86 x 86 inch footprint, rated to a 1.5 specific gravity. That SG rating is the headline number on this tank: it means the polyethylene wall is engineered to carry contents up to one-and-a-half times the weight of water, so a full load of plain water at 1200 gallons sits well inside its structural envelope. Filled with water this tank holds 10,008 pounds of liquid; at its full 1.5 SG rating the wall is built to support up to 15,012 pounds of contents. Those two weights are the first thing to plan around when you spec the pad and the access.
Does this vertical storage tank work for your job?
This is a vertical storage tank for water and water-like liquids. Verify the listed specific gravity against whatever you intend to store: at 1.5 SG it handles standard process and stored water with substantial structural margin, and it covers heavier-than-water liquids only up to that 1.5 ceiling. The technical drawing on this page shows the fitting layout, which on this unit includes an 8" x 7.5" flat fitting, a 2" polypropylene bulkhead fitting with an EPDM gasket, and a 20" vented manway up top for fill access, inspection, and venting as the tank breathes during fill and draw-down. The 8" x 7.5" flat fitting gives you a large, reinforced flat landing for an outlet bulkhead or self-aligning fitting, and stainless lid screws are specified for the manway hardware. Confirm those fitting positions and the manway diameter against your plumbing and any equipment that has to clear the top before you order.
Sizing the pad and the contents
The 86 x 86 inch footprint and 10,008 pound full-water weight drive your foundation. A vertical tank of this size needs a level, fully supporting pad — concrete or compacted base — rated for the full 15,012 pound 1.5 SG load, not just the water figure, so you keep margin if you ever move to a denser liquid. If you are still narrowing capacity or comparing this 1200 gallon white vertical to a taller or shorter unit, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide. For fire-protection reserve use, our guide to fire-water reservoir tank design walks through NFPA 22 reserve sizing and cold-climate freeze protection, and our buyer's guides step down through the 300 gallon, 500 gallon, and 2000 gallon verticals to help you step up or down in size.
The mistake to avoid
The common error on a 1.5 SG tank is treating the rating as headroom you can spend freely. The 1.5 specific gravity is a structural limit, not an invitation to store any heavy liquid — it tells you the wall thickness supports up to 1.5x water density, but it says nothing about whether the wetted materials chemically tolerate a given product. Compatibility here is governed by three materials, not one: the polyethylene wall, the polypropylene bulkhead fitting, and the EPDM gasket, and each has its own chemical tolerance. This is a water-service listing; keep it on water and water-like liquids unless you have separately confirmed compatibility against all three wetted materials for what you intend to store — we can swap fitting and gasket materials on request. The second mistake is undersizing the pad to the 10,008 pound water weight when the tank is rated for 15,012 pounds of contents — build the foundation to the rated load.
