The Snyder Industries 1000 Gallon HDPE Vertical Liquid Storage Tank holds 1,000 gallons in a polyethylene tank built and shipped from Snyder's Chowchilla, California plant. It stands 89 inches tall on a 60 by 60 inch footprint, so before you order, confirm the pad and any doorway or roofline along the delivery path can clear that height. The tank carries a 1.9 specific gravity rating, which means the wall is engineered for liquids up to 1.9 times the weight of water - more headroom than a plain water-only vertical tank, and useful if your stored liquid is ever denser than water.
Does it work for your site?
Filled with water (specific gravity 1.0), this 1000 gallon vertical storage tank carries roughly 8,340 pounds of contents. At its full 1.9 SG rating the wall is designed to support up to 15,846 pounds of liquid - the same 1,000 gallons, but nearly double the contents weight. That gap is the reason to pick this 1.9-rated unit over a plain water tank if you ever store brine, fertilizer, or any liquid heavier than water. Either way, the structure is not your limiting factor - the pad is. That 15,846-pound full-rated load sits on a 60 x 60 inch (25 square foot) base, about 630 pounds per square foot, so spec a smooth, level, fully supporting concrete pad to that load with no gravel point-loads under the base. Use the Tank Sizing Calculator and Tank Sizing Guide if you are still confirming that 1,000 gallons matches your draw and refill cycle.
Fittings and access
Per the technical drawing on this page, this tank is configured with three distinct components: a flange, an 18-inch polyethylene threaded and vented lid, and a manway with 15-inch access. The flange is your bulkhead plumbing connection for inlet and outlet - it is separate from the manway, so do not plan to plumb through the manway opening. The 15-inch manway access is for reaching inside to clean and inspect. The vented lid matters too: a sealed lid on a tank you fill and draw frequently can pull a vacuum or build pressure, so keep that vent clear. Confirm the flange location against the drawing before you plumb. The flange and lid seat on HDPE and elastomer seals, so for any liquid denser or more aggressive than water, confirm gasket material compatibility with your specific liquid before commissioning.
The mistake to avoid
The common error on a tank this tall is treating the 1.9 SG rating as a free upgrade and skipping the pad. At nearly 90 inches of standing liquid, uneven support concentrates stress in the lower wall - the HDPE wall-thickness guide on this page walks through why that headspace and lower-wall region is where premature failures originate. If you are pairing this with rural fire-water service, or want to understand how ASTM D1998 sizing actually works, the NFPA 22 fire-water reservoir sizing guide and the natural-white 1000 gallon vertical tank buyer's guide on this page are worth reading before you buy.
