The Snyder Industries 3650 Gallon Black Heavy Duty Vertical Storage Tank is a high-capacity polyethylene vertical storage tank built for bulk water and dense-liquid service. It carries 3,650 gallons in a 102 in. by 102 in. footprint, stands 126 in. tall, and is rated to a 1.9 specific gravity, so it handles liquids heavier than water up to that density. This is the Black variant: an opaque wall that blocks light to the stored liquid, distinguishing it from translucent gallon-marked tanks.
Will it work for your site?
Before you order, run three checks against your site. First, the base: this vertical tank sits on a level 102 x 102 in. footprint that must be fully and evenly supported. Second, vertical clearance: at 126 in. tall you need overhead room for the tank plus lid and fill access. Third, and most important, the loaded weight your pad has to carry. Water alone, at specific gravity 1.0, loads this tank to 30,441 lb when full; at its maximum 1.9 specific-gravity rating, contents reach 57,838 lb. Size the slab to that loaded figure for the liquid you are actually storing, not the empty shell. Use the Tank Sizing Calculator to match the 3,650-gallon capacity to your real draw and refill cycle, and the Tank Sizing Guide to read footprint against the space you have.
Specifications at a glance
Capacity is 3,650 gallons in a black polyethylene vertical storage tank measuring 126 in. high by 102 in. wide by 102 in. long, rated to a 1.9 specific gravity. Empty (shell) weight, bulkhead fitting sizes, gasket materials, and outlet locations are not standardized on this listing, so confirm them against the technical drawing on this page or by phone before you finalize the pad and order plumbing. For larger-system context, see our fire-water reservoir design guide and our industrial water reuse topology guide.
The mistake to avoid
Do not under-build the foundation. A 3,650-gallon tank holding water already exceeds 30,000 lb, and at the full 1.9 specific-gravity rating it pushes past 57,000 lb of contents. Pouring a slab sized for the empty tank, or setting it on uncompacted ground, is the failure mode that ends these installations early. Walk through our concrete pad sizing guide, size the pad to the loaded weight, keep the base evenly supported, and confirm the heaviest contents you will ever store stay within the 1.9 rating. If you are running this tank near that density ceiling, our Snyder Captor freeboard and density guide covers how specific gravity and thermal expansion cut into the usable volume you can actually fill.
