The Snyder Industries 290 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a polyethylene vertical storage tank built for durable bulk water and liquid holding. It stands 72 inches tall on a 36 x 36 inch footprint, so it fits a compact pad while still carrying real volume. Snyder rates this tank to a 1.9 specific gravity, the top of the range for a polyethylene vertical tank, which makes it the tank to reach for over a standard 1.35 or 1.5 SG water tank if you might later store brine, fertilizer, or other liquids heavier than plain water.
Will it work for your site?
At 290 gallons of capacity, a full load of water weighs about 2,419 pounds, and the tank is rated to carry contents up to roughly 4,595 pounds at its 1.9 specific gravity ceiling. The molded fittings shown on the technical drawing include a flange outlet, an 18-inch PE threaded and vented top opening, and a manway with 15-inch access. That 15-inch clear opening is wide enough to reach a hand and tools inside for a full interior wash-down, cleaning, and inspection. Review the technical drawing on this page to confirm outlet placement and thread sizes line up with your plumbing before you order. If you are still working out how much storage you need, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching capacity to your draw and refill cycle.
What it is good for
This is a straightforward black vertical tank for water storage, and the opaque black wall helps limit light penetration that encourages algae growth in stored water. It works well as a general bulk water reservoir, and for rural and remote sites our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. If you are setting this on a new above-ground pad, our concrete pad sizing guide lays out the ACI framework so the base carries the loaded weight without cracking.
The mistake to avoid
Do not size the pad or skip anchoring based on the empty weight. Plan the foundation around the maximum rated contents weight: roughly 4,595 pounds bearing on a 36 x 36 inch (9 square foot) footprint is the load your pad and anchoring have to carry, which is exactly why the ACI pad guide above is worth reading before you pour. A vertical tank this tall becomes top-heavy and load-sensitive once it is full, and the 1.9 specific gravity rating exists so you can store denser liquids, not so you can ignore the structural load they add. If you do plan to store anything heavier than water, our Snyder freeboard sizing guide walks through how density and thermal expansion cut into the volume you can actually use. And match the wetted flange gasket, the replaceable seal at the outlet, to that liquid, since the gasket is the real compatibility failure point long before the polyethylene wall is.
