The Snyder Industries 8000 Gallon XLPE Vertical Liquid Storage Tank is a cross-linked polyethylene vertical tank built for high-density bulk storage, rated to 1.9 specific gravity and built to the ASTM polyethylene tank standard. At 120 inches in diameter and 186 inches tall, it holds a full 8,000 gallons on a 120.0 x 120.0-inch footprint, making it a workhorse for water reservoirs, fire-protection supply, and heavy-liquid storage where a smaller-rated tank would be overloaded. If you have been searching for a vertical storage tank in XLPE at this capacity, this is the Snyder build.
Will this tank work for your application?
This is a white XLPE vertical tank with a 120-inch diameter and 186-inch overall height. The 1.9 specific gravity rating is the number that matters most: it tells you the maximum liquid density the tank wall is engineered to hold. Plain water has a specific gravity of 1.0, so at a full 8,000 gallons of water the contents weigh roughly 66,720 lb. Because the wall is rated to 1.9 S.G., the maximum rated contents weight climbs to about 126,768 lb, which is the headroom that lets this tank handle denser liquids than water. Match your liquid's actual specific gravity against that 1.9 rating before you order. One honest caution in both directions: this 1.9 S.G. XLPE build is the heavy-duty tier above a standard 1.0 or 1.5 S.G. HDPE tank of the same gallonage, so if you only store water, confirm whether you truly need the XLPE premium or whether a standard-rated tank will serve. If you are unsure how this size fits your draw-down and refill cycle, the Tank Sizing Calculator and the Tank Sizing Guide walk through the math.
Specifications and fittings
Key dimensions: 120-inch diameter, 186-inch height, 8,000-gallon capacity, white XLPE, 1.9 S.G. rating, built to the ASTM D1998 polyethylene tank standard. One thing this listing does NOT define is the fitting and bulkhead layout: confirm outlet size and position, manhole, and vent against the Snyder technical drawing on this page before ordering, because on a tank this size those details decide whether it drops onto your pad and plumbs to your existing run. XLPE is the cross-linked resin Snyder uses for its higher-density and tougher-duty vertical tanks. If you want to understand how wall thickness is sized across the height of a tank this tall, the guide to HDPE wall thickness and ASTM D1998 sizing logic covers exactly that.
The mistake to avoid
The single most common error on a tank this large is treating the 1.9 S.G. rating as optional. It is the ceiling on liquid density, not a suggestion. A tank rated to 1.9 will safely hold water, but the reverse is never true: do not put a 1.9 S.G. liquid into a tank rated to 1.0 or 1.5. The wall rating is also only one path to failure. Density and chemical compatibility also depend on the fitting hardware and gasket material at every penetration, which are specified separately from the tank shell, so verify the gasket elastomer and bulkhead fitting rating against your liquid, not just the 1.9 S.G. tank rating. For fire-water reservoir duty in particular, size for the full standing volume and freeze protection up front rather than retrofitting; the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate engineering for exactly this kind of vertical storage tank.
Note that the 66,720 lb and 126,768 lb figures are filled operating weights for pad and foundation sizing, not shipping weight: the empty tank ships LTL, but your foundation must be engineered for the full 66,720 lb water load and up to roughly 126,768 lb at 1.9 S.G. This tank ships LTL freight from the nearest Snyder plant to you among Lincoln, NE; Marked Tree, AR; Merced, CA; and Philippi, WV, with freight quoted live to your ZIP. Plant assignment depends on stock and your ZIP, so run the Freight Cost Estimator or call 866-418-1777 to confirm origin and landed LTL cost before you commit, and we will route the order from the closest plant to keep your freight down.
