The Snyder Industries 4500 Gallon Black Heavy Duty Vertical Storage Tank is a 142-inch-tall polyethylene vertical storage tank on a 102 x 102-inch footprint, built for high-volume bulk water storage where a smaller tank would force a second delivery or a second pour. Rated to a 1.9 specific gravity, it is built to carry contents denser than plain water within that rating, which is why it shows up under searches for a heavy-duty black vertical storage tank rather than a light-duty water-only body.
Will it hold what you need it to hold
Capacity is 4,500 gallons of usable storage in a single black vertical body measuring 102 inches in diameter and 142 inches tall - just under 11 feet 10 inches. At that height, overhead clearance is a real check before you order: confirm door heights, eaves, roll-up openings, and any overhead obstruction at the set-down point, because at nearly twelve feet this is a clearance-and-rigging problem, not only a slab problem. Filled with water, the contents alone weigh 37,530 pounds; at the tank's full 1.9 specific-gravity rating, the maximum rated contents weight is 71,307 pounds. Those two numbers matter before you order: water is your floor, and 1.9 SG is your ceiling. If you are storing anything denser than water, plan your slab and your anchoring against the rated weight, not the water weight. Confirm your liquid's specific gravity first, then size against the 71,307-pound rated contents figure.
Foundation and siting
Run the math on your pad before the truck arrives. At full 1.9 SG, 71,307 pounds spread across the 102 x 102-inch footprint works out to roughly 6.85 psi of average bearing pressure - a concrete starting load to hand your slab engineer. A flat, fully supporting, properly engineered concrete pad under the entire base is not optional on a tank this size. For slab guidance, see our concrete pad sizing guide, and to confirm 4,500 gallons is genuinely the right volume for your draw and refill cycle, run the Tank Sizing Calculator or read the Tank Sizing Guide before committing. If this tank anchors a fire-water reserve, our fire-water reservoir design guide walks through NFPA 22 sizing and freeze protection for cold-climate sites. For reclaimed and blended supply, the industrial water reuse topology guide covers folding grey-water, rainwater, and condensate into a storage train built around a tank like this one.
The mistake to avoid
The most common error on a high-SG vertical tank is treating the 1.9 rating as headroom rather than a limit. The 71,307-pound rated contents weight is the hard ceiling for the densest liquid this tank is rated to hold; plan your contents, foundation, and fittings around that number, not around the lighter 37,530-pound water weight. Fitting placement, outlet size, and bulkhead locations are fixed at the manufacturing plant and are not field changes on a tank this size, so confirm the exact fitting and outlet configuration you need with us before your order goes to production - we will not publish a fitting spec we cannot verify for your unit.
This tank ships LTL freight, quoted live to your ZIP, from the nearest of two Snyder plants - Chowchilla, CA or Lincoln, NE - so West-of-Rockies buyers pull from California and Central and Eastern buyers pull from Nebraska, which keeps your LTL miles shorter than a single-plant supplier. Get an exact freight number with our Freight Cost Estimator, or call 866-418-1777 and we will quote it for you and confirm pad, fitting, and delivery details before your order goes to production.
