The Snyder Industries 3600 Gallon Open Top Batch Storage Tank (SKU SII-5950000N43) is a white, cylindrical open-top tank built for bulk water batching, mixing, and high-volume storage where you need top access for filling, dosing, agitation, or manual inspection. It holds 3,600 gallons, stands 108 inches tall on a 102 x 102 inch footprint, and is molded by Snyder Industries from polyethylene with a 1.5 specific gravity rating, so it carries contents heavier than water without exceeding its design margin.
Will it work for your batch?
This is a true open top storage tank, not a closed vertical, so plan for an unconfined top: that is what makes it useful for mixing and access, but it also means there is no sealed vapor space. The 102 x 102 inch footprint is square to the tank's outer diameter, so size your pad to the full 102-inch width plus working clearance. Filled with water, this tank weighs about 30,024 pounds; at its maximum rated 1.5 specific gravity contents it reaches roughly 45,036 pounds. Those are the numbers that drive your foundation, not the empty shell weight. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 3,600 gallon working volume fits your batch cycle, and because freeboard during mixing and agitation matters on an open top, our Snyder freeboard sizing guide walks through how much usable volume you actually get before sloshing or overflow.
Fittings, SG rating, and the mistake to avoid
This tank has no factory-plumbed fittings listed, so confirm outlet, drain, and overflow provisioning before you plumb; an open top batch tank of this size is often set up with field-added connections. That matters because the 1.5 specific gravity rating applies to the polyethylene shell only: it means the molded body is rated to carry fluids up to 1.5 specific gravity, roughly 12.5 pounds per gallon, but it is a ceiling, not a default. Any field-added outlet, bulkhead fitting, or gasket is a separate compatibility decision based on material, specific gravity, and the fluid itself, not something the shell rating covers. The most common mistake on a tank this size, though, is underbuilding the base: 45,036 pounds concentrated on a 102 x 102 inch footprint demands a properly engineered, level concrete pad. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab actually carries the static load. Refer to the technical drawing on this page for overall dimensions before you set anchors.
Fit for water reuse and reservoir duty
Because the top is open, this tank suits grey-water, rainwater, and condensate aggregation where you stage and treat water in batches. Plan for a cover or screening against debris, evaporation, and airborne contamination, since the open top leaves stored water exposed. If you are designing a quality-banded storage train, our guide on industrial water reuse tank topology covers treatment-stage sequencing. For rural fire-water reservoir use, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection.
