The Snyder Industries 4100 Gallon ASTM XLPE Black Vertical Storage Tank is a crosslinked polyethylene vertical storage tank built for high-density bulk water and demanding storage duty. Molded in black crosslinked linear polyethylene (XLPE) with a 1.5 specific-gravity rating, this Snyder vertical tank stands 130 inches tall on a 102 x 102 inch footprint and holds 4,100 gallons. The 1.5 SG rating means it is engineered to hold liquids up to 1.5 times the weight of water, giving it more structural margin than a standard 1.0-rated water tank and a full column of water with room to spare.
Will this tank work for your site?
Water fills this tank to roughly 34,194 pounds, and the tank is rated to carry contents up to 51,291 pounds — that is more than 17,000 pounds of contents headroom over plain water, and it is why the 1.5 SG rating matters. The pad and soil under it have to be engineered for that full load, not just the empty shell. Plan for the real 102 x 102 inch footprint when you lay out site clearance, and size a reinforced concrete pad to the full 102-inch diameter before you order. Our concrete pad sizing guide walks through the ACI 360R-10 framework, and if you are still confirming capacity for your draw-down or reservoir needs, run the numbers through our Tank Sizing Calculator and Tank Sizing Guide.
Fittings and access
Per the technical drawing on this page, this vertical tank is configured with a flange, an 18-inch PE threaded/vented fitting, a manway with 15-inch access, a 12 x 23 inch fitting, and a flat fitting location. The 15-inch manway access lets a crew reach inside for inspection and cleaning without cutting the tank. Confirm every fitting location and outlet elevation against the drawing before you set piping, and confirm the flange and 15-inch manway gaskets are rated for your stored liquid before commissioning. The vented fitting matters for a tank this size, because a sealed vertical tank can pull a vacuum on fast draw-down and collapse the wall. For freeboard and usable-volume planning on ASTM D1998 tanks like this one, our ASTM D1998 freeboard sizing guide covers the numbers you can actually use.
A common mistake to avoid
The most frequent error on a tank this large is treating a 102-inch-diameter, seventeen-ton (full) tank like a small poly drum you can shift after it is set. Once it is placed and filled it does not move — dry-fit the plumbing, verify the vent is open, and confirm your pad is level and cured first. Because this is a crosslinked (XLPE) rather than a standard HDPE tank, it is the right choice when you want extra wall integrity for bulk water, a fire-water reservoir, or an industrial water-reuse train. Our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection for cold-climate service, and our industrial water reuse topology guide shows where a tank this size fits in a quality-banded storage train.
This Snyder vertical storage tank ships LTL freight from the Philippi, West Virginia plant, quoted live to your ZIP. Because that is an East-Coast origin, buyers west of the Mississippi should expect longer LTL lanes and pull a live quote early.
