The Snyder Industries 3000 Gallon Black Heavy Duty Vertical Storage Tank (SKU 8160000C34) is a 3,000-gallon polyethylene vertical storage tank built for bulk water and high-density liquids. Its black resin blocks sunlight to suppress algae growth in stored water, and the standout number is the 1.9 specific gravity rating: a heavy-duty wall structure engineered to hold liquids far denser than water, which is the detail that separates it from a standard 1.5 SG vertical tank.
- Capacity: 3,000 gallons
- Dimensions: 127 in tall on a 90 x 90 in footprint
- Full water weight: ~25,020 lb loaded
- Max rated contents weight (1.9 SG): ~47,538 lb
- Material: polyethylene, black
Will it work for your site?
Filled with water, this tank carries roughly 25,020 pounds of contents at full volume. Rated to its full 1.9 specific gravity, it is engineered for a maximum contents weight of about 47,538 pounds, so the wall is sized for liquids well beyond plain water. Plan the pad to the loaded weight, not the empty shell. The 90 x 90 inch footprint and 127-inch height determine your slab size, overhead clearance, and access for fill and discharge plumbing. Fitting sizes and positions are defined by the technical drawing on this page, which is the single source of truth here, so confirm them before you order plumbing or set the tank. Use the Tank Sizing Calculator and Tank Sizing Guide to match capacity to your draw rate and refill cycle.
Foundation and water-system planning
A vertical storage tank this size needs a flat, fully supported base. At more than 25,000 pounds loaded with water alone, the slab has to carry the full footprint with no voids or overhang. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for sizing that pad. If this tank is going into a fire-protection reservoir, rainwater capture, or a reuse train, two more references help size it correctly: fire-water reservoir tank design and NFPA 22 sizing discipline and our industrial water reuse tank topology overview.
The mistake to avoid
The most common error on a tank like this is treating the 1.9 specific gravity rating as a license to store anything heavy without a compatibility check. The 1.9 SG figure tells you the structure can carry the weight of a dense liquid; it does not by itself certify the resin against a specific chemical. Before you put anything other than water in this tank, run a three-part gate at your actual concentration and temperature: first resin compatibility against the manufacturer chemical-resistance chart, then gasket material, then fitting material. Our breakdown of freeboard sizing per ASTM D1998 explains how density and thermal expansion eat into the volume you can actually use, which ties directly to this tank's 1.9 SG rating. For plain water storage, size the tank to your peak demand rather than your average, so you are not caught short during a draw-down.
