The Snyder Industries 4100 Gallon Vertical Liquid Storage Tank is a large-format white HDPE (High Density Linear Polyethylene) vessel built for bulk water and liquid storage where a single tank has to hold a serious column of fluid. It stands 130 inches tall on a 102 by 102 inch footprint and carries a 1.9 specific gravity rating - the engineering headroom that decides whether one tank can cover your entire storage requirement.
Will this vertical tank work for my application?
Filled with water, the 4100 gallons inside this tank weigh roughly 34,194 pounds. Because it is engineered to a 1.9 specific gravity rating, its maximum rated contents weight is 64,969 pounds. That is real headroom above plain water - room for denser liquids and for the dynamic and seismic loads a tall vertical tank sees in service, all within rating. The number that matters for your install is the gap between the two: a base designed only to the 34,194-pound full-water weight is undersized by 30,775 pounds, about 90 percent, against the 64,969-pound rated load. Build the pad to the rated figure, not the water figure.
Sizing, placement, and clearances
Plan the site around a 102 inch by 102 inch level pad with 130 inches of vertical clearance, plus additional overhead room for the vent stack and top fill access. A fully loaded vertical tank concentrates tens of thousands of pounds onto that footprint, so it needs a continuously supported, engineered concrete base sized for the full loaded weight. Inlet, outlet, and vent placement is configured per order, so call 866-418-1777 to spec your fitting layout before you set the tank - that placement on a 130-inch-tall vessel determines your plumbing runs and overflow routing. If you are weighing this against smaller vessels, our Tank Sizing Calculator and Tank Sizing Guide match capacity, footprint, and refill cadence to your draw rate. For rural fire-protection storage at this scale, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and cold-climate freeze protection for polyethylene tanks.
The mistake to avoid
The most common error on a tank this size is underbuilding the foundation and inspecting only the liquid side. HDPE vertical storage tanks tend to age fastest at the vapor-saturated headspace above the liquid line - a zone that liquid-side inspection misses entirely. Our guide on HDPE tank wall thickness at the vapor-saturated headspace explains where premature failures originate and the ASTM D1998 sizing logic operators should understand. Pair that with a base built for the full 64,969-pound rated load and this vertical tank will give you decades of dependable service.
This 4100 gallon vertical tank ships LTL freight, quoted live to your ZIP. We stock it at two plants - Albertville, Alabama and Merced, California - so a buyer in the Southeast or on the West Coast gets a materially shorter LTL lane on a unit that runs 34,194 pounds of water and up to 64,969 pounds rated, where freight is a large share of freight cost. Get an exact freight number with our Freight Cost Estimator, or call 866-418-1777 to confirm fitting layout, lead time, and delivery for your site.
