The Snyder Industries 3650 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a full-size bulk storage vessel molded from polyethylene. It stands 126 inches tall and is 102 inches in diameter, setting on a 102 x 102 inch square footprint. It holds 3,650 gallons and carries a 1.9 specific gravity rating, meaning the shell is rated for contents up to 1.9 times the density of water rather than water alone. As a heavy-duty black vertical tank built to ASTM, it is sized for serious bulk water storage where the load and standing weight matter as much as the gallons.
Will it work for your site?
Plan your foundation around real loaded weight, not just capacity. Filled with water this tank carries roughly 30,441 pounds of contents, and at its full 1.9 SG rating it is engineered for up to about 57,838 pounds of contents. That load rides on a 102 x 102 inch footprint, so the pad underneath needs to be sized, level, and rated for the full standing weight. If you are working through pad thickness and bearing, our concrete pad sizing guide for above-ground polyethylene tanks walks the ACI framework, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 3,650 gallons is the right volume before you commit.
Fittings and access
This vertical storage tank is configured with a flange, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access for entry and inspection. It also carries a 12 x 13.75-inch fitting and self-locating S.U.M.O. flat bulkhead fittings. Confirm each fitting position, size, and count against the technical drawing shown on this page before you set the tank and rough in piping, since the outlet layout drives where your pad penetrations and supports need to land. Gaskets, seals, and bolt kits are not detailed here, so call 866-418-1777 to confirm gasket and bulkhead-seal specs against the drawing before you plumb your connections.
Fire-water and reuse storage
At 3,650 gallons this size lands squarely in the range used for rural fire-water reservoirs and industrial water-reuse trains. If you are storing for private fire protection, our fire-water reservoir tank design guide covers NFPA 22 sizing and cold-climate freeze protection. For grey-water, rainwater, and condensate aggregation, the industrial water reuse tank topology guide shows how a vertical tank this size fits into a quality-banded storage train.
