The Snyder Industries 4400 Gallon ASTM Black Vertical Storage Tank is a full-size polyethylene bulk water tank built for high-volume storage where a large standing footprint and serious rated capacity matter. It stands 182 inches tall on a square 90 x 90 inch base, holds a rated 4,400 gallons, and carries a 1.5 specific gravity rating. Because water itself is SG 1.0, that 1.5 rating means the tank wall is engineered to carry contents up to 50 percent denser than water - so for plain water service you are well inside the tank's rated envelope. This is a black polyethylene vertical storage tank, and the black wall limits light penetration to slow algae growth in outdoor standing water.
Will it work for your site?
Plan your pad and structural support around real loaded weight, not the empty shell. Filled with water this tank carries roughly 36,696 pounds, and at its full 1.5 SG rating the contents can reach about 55,044 pounds. That load rides on a 90 x 90 inch footprint, so a level, fully supporting concrete pad is not optional. Because both the width and length are 90 inches, your offload and staging area has to clear a full square base, not just the pad. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm the capacity and dimensions fit before you commit, and the concrete pad sizing guide walks the ACI framework for a base carrying this kind of load. If you are working the difference between rated volume and usable volume on an ASTM D1998 Snyder tank, the Snyder freeboard sizing guide covers freeboard discipline.
Fittings and access
Per the technical drawing on this page, this vertical storage tank is configured with a flange, an 18 inch PE threaded and vented fitting, a manway with 15 inch access, a 2-3 inch S.U.M.O. fitting, a 12 inch by 14 inch fitting, and a flat fitting provision. The 15 inch manway access gives you a practical entry point for inspection and cleaning on a tank this tall. Confirm each outlet size and position against the drawing before you plumb, since the flange, threaded, S.U.M.O., and manway penetrations each drive your inlet, outlet, and vent routing. Verify gasket material and the flange or bulkhead seal against your fluid and mating pipe thread before final assembly.
A common mistake to avoid
The biggest planning error on a tank this size is underbuilding the foundation and fill logistics. At more than 36,000 pounds of standing water concentrated on a small square base, a marginal or uneven pad will crack or let the tank settle out of plumb. If you are sizing this for fire-water reserve or reuse storage, review the fire-water reservoir design guide and the industrial water reuse topology guide to band your storage correctly.
