The Snyder Industries 175 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 175-gallon polyethylene vertical storage tank rated to 1.9 specific gravity, a heavy-duty rating. It stands 66 inches tall on a compact 29 x 29 inch footprint, so it tucks into a corner while still holding real volume. If you are working through a black vertical tank or general storage tank decision, this is a straightforward, well-supported choice.
Will it work for your site?
The tank measures 66 inches tall by 29 inches wide and 29 inches deep, giving it a 29.0 x 29.0 inch footprint. Filled with plain water, the contents weigh about 1,460 pounds. But the number to design around is the heavy-duty rating: at its full 1.9 specific gravity, the tank is built to carry up to 2,773 pounds of contents. That 1.9 rating means the wall thickness supports denser liquids than water, so you have real headroom if your stored fluid weighs more than water. Note that 1.9 is the ceiling for this SKU: fluids denser than 1.9 specific gravity are out of spec here, and there is no higher-rated version of this tank offered.
Sizing and pad planning
The black exterior blocks light, which helps limit algae growth in stored water. Because a 66-inch-tall tank on a small 29 x 29 inch base carries a relatively high center of gravity when full, size your foundation for the full 2,773-pound rated contents load, not the lighter water figure. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm this 175-gallon size fits your daily draw and refill cycle, and our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for building a base that supports that full rated load without point-loading the tank floor.
The mistake to avoid
The common error on a tank this size is undersizing the foundation. A tall, narrow tank on a small 29-inch square footprint must sit on a rigid, level, fully supporting surface and be anchored if it is exposed to wind while empty. Do not set it on bare soil, gravel, or a partial support. Confirm your intended contents against the 1.9 specific gravity rating before filling, and confirm outlet and fitting sizes for your plumbing at the time of order, since fitting configuration is set per order rather than published here.
