The Snyder Industries 3000 Gallon HDPE Vertical Liquid Storage Tank (SKU SII-8160000N39) is a 90" diameter, 127" tall vertical tank molded in white high-density linear polyethylene and rated to a 1.4 specific gravity under ASTM. That 1.4 rating is heavier than water, so the same tank covers brine, some fertilizers, and denser process liquids without stepping up to a thicker-walled model. Filled with water it holds 25,020 lb, and the wall is engineered to carry contents up to 35,028 lb at the 1.4 rating. It ships LTL from one Snyder plant in Marked Tree, Arkansas, so you can size freight to your ZIP before you order. If you have been searching for a vertical storage tank in HDPE at the 3000-gallon size, this is the Snyder build that fits.
Will it work for your site?
Run the clearance and load check before you commit. You need a 90" diameter slab or ring wall minimum and 127" of vertical clearance on the full install path - roof line, doorway, and overhead obstructions. Then build the foundation for weight: a full water column is over 25,000 lb, and at the rated 1.4 specific gravity the tank is built to carry up to 35,028 lb of contents, so the pad and any anchoring need to be sized for the heaviest liquid you intend to store. Use the Tank Sizing Calculator and the Tank Sizing Guide to match the 3000-gallon capacity to your actual draw and refill cycle.
Fittings and access
This tank is configured with a flange, an 18" PE threaded and vented fitting, and a manway with 15" access for inspection and cleaning. Confirm your inlet and outlet plumbing matches the flange and the 18" PE threaded fitting, and that any camlock or bulkhead gaskets are HDPE-compatible, before you plumb it. The technical drawing on this page shows fitting locations and elevations - review it against your plumbing and overflow plan before you finalize the order.
The mistakes to avoid
Two errors trip up tanks this size. First, under-building the foundation for the water load instead of the rated load - size the pad and anchoring for the heaviest liquid you intend to store at the 1.4 SG rating, not just for water. Second, the gallon markings: the drawing notes that some gallonage marks may be removed where fittings are placed, so if you depend on side-wall markers for level monitoring, confirm the fitting layout doesn't erase the range you need, or plan for a level gauge or sensor instead. For wall behavior over the life of the tank, the guide on HDPE tank wall thickness and ASTM D1998 sizing logic explains why the vapor-saturated headspace matters even when the liquid side looks sound. For private fire-protection storage, the fire-water reservoir design guide covers NFPA 22 sizing for a tank in this range.
