The Snyder Industries 4400 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a full-scale bulk vertical storage tank molded from polyethylene, standing 182 inches tall on a 90 x 90 inch square footprint. Rated to a 1.9 specific gravity, it is engineered to hold dense contents most water and light-liquid tanks cannot, which is what puts it in the heavy-duty class among vertical storage tanks. If you are sizing a black vertical tank for bulk water, fire-water reserve, or industrial reuse duty, the numbers below tell you exactly what this Snyder tank can carry and how it ships.
Will it work for your site
Filled with water, this tank carries roughly 36,696 pounds of contents, and at its full 1.9 specific gravity rating it is engineered for a maximum rated contents weight near 69,722 pounds. That difference matters: the tank is built for liquids substantially heavier than water, so water service leaves you comfortable headroom, while dense-liquid service uses the full structural envelope. The product name references the ASTM standard for large rotationally molded polyethylene tanks (ASTM D1998); our D1998 freeboard sizing guide explains how density affects the usable volume you can actually plan around. Confirm your loaded weight with the Tank Sizing Calculator and the Tank Sizing Guide before you pour a pad. Because a filled tank of this size concentrates tens of thousands of pounds onto a 90 x 90 inch footprint, foundation work is not optional reading — see our guide on concrete pad sizing for above-ground polyethylene tanks for the ACI framework that keeps a tank this heavy level and supported.
Fittings and access
Per the technical drawing on this page, the tank comes 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 x 14 inch fitting, and a flat fitting location. Verify the S.U.M.O. count and bore against the on-page drawing callout before you plumb it, since the drawing is the authority on quantity and size. The 15-inch manway access supports inspection, cleanout, and service entry, and the vented fitting is important — a tank this size must breathe as it fills and drains, so do not cap or plumb over the vent. At the outlet, match your bulkhead fitting and gasket to the molded fitting size shown on the drawing and hand-tighten to seat the gasket without over-torquing the poly boss; that connection is the single most common leak point on a tank this size.
Bulk water, fire reserve, and reuse duty
At 4,400 gallons this black vertical storage tank suits rural and remote fire-water reservoirs, agricultural and industrial bulk water, and quality-banded reuse storage. The black resin limits light transmission into the stored water. For fire-protection sizing discipline, our write-up on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing and cold-climate freeze protection, and if you are aggregating grey-water, rainwater, or condensate, our industrial water reuse tank topology guide maps how a bulk storage tank like this fits a treatment train.
This tank ships LTL freight from the Snyder plant in Lincoln, Nebraska, quoted live to your ZIP code. At 182 inches tall on a 90-inch-square base, an empty-tank LTL delivery of this size needs forklift or crane offload arranged on your end — plan that before the truck arrives. Get a freight rate in seconds with our Freight Cost Estimator, or call 866-418-1777 and we will quote it with you and confirm offload requirements for a tank of this weight.
