The Snyder Industries 4650 Gallon ASTM Black Vertical Storage Tank (SKU 8210000N49) is a large-volume polyethylene vertical built for bulk water and general liquid storage. It holds 4,650 gallons in a 102-inch diameter footprint and stands 154 inches tall, putting serious capacity on a compact 102 x 102-inch pad. The tank is molded to ASTM D1998, the standard that governs one-piece polyethylene upright storage tanks, so the "ASTM" in its name is a verifiable manufacturing spec, not a label. Its black polyethylene shell blocks UV and suppresses algae growth in stored water, and it carries a 1.5 specific gravity rating that gives you density headroom above plain water if you later store a heavier liquid.
Will it work for your site?
Plan your slab and structural support around real numbers, not nameplate volume. Filled with water this tank weighs about 38,781 lb, and at its full 1.5 SG rating the contents alone can reach 58,172 lb. That 58,172 lb figure assumes filling to the top at 1.5 SG, so treat elevated-density service as a working-volume question: leave freeboard rather than reading the SG rating as free capacity. The freeboard math in our Snyder freeboard sizing guide (ASTM D1998) shows how density and thermal expansion cut into usable volume. Run your capacity and load through the Tank Sizing Calculator and Tank Sizing Guide before you pour, and size the concrete for the filled condition using our guide on concrete pad sizing for above-ground polyethylene tanks.
Fittings, venting, and access
The tank comes configured with a flange, a 12" x 13.75" S.U.M.O. flat fitting, additional S.U.M.O. and S.U.M.O. flat fittings, an 18" polyethylene threaded and vented fitting, and a manway with a 15" access opening. The 18" vented fitting handles atmospheric venting during fill and draw, which matters on a 154-inch-tall water column where a fast draw-down can pull vacuum and collapse an unvented tank; the 15" manway is for interior inspection and cleaning. Confirm the fitting layout against the technical drawing on this page so your plumbing, overflow, and vent lines match what is molded and cut into the tank. Threaded, flanged, and bulkhead-style connections seal on gaskets, so match the gasket elastomer (EPDM or Viton) to your stored liquid before you plumb it.
Sizing for the water you actually store
This is a vertical storage tank built for standing water columns, whether that is bulk water supply, irrigation, process makeup, or a rural fire-water reserve. If your project is fire protection, our fire-water reservoir tank design guide covers NFPA 22 sizing and freeze protection.
