Snyder Industries 300 Gallon ASTM Black Heavy Duty Vertical Storage Tank

The Snyder Industries 300 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 300-gallon polyethylene vertical tank built to ASTM standards, standing 51 inches tall on a 46 x 46 inch footprint. Its black polyethylene wall blocks light to slow algae growth and suits outdoor, non-potable storage such as rainwater capture, supplemental water reserve, and general bulk water holding. If you are weighing capacity against the space you have, this footprint and height put a full 300 gallons in a compact vertical package.

Will this tank work for your site?

Filled with water, the tank carries about 2,502 pounds of contents, so the pad or slab underneath it has to be rated for that load plus the tank's own weight, sitting level and fully supported across the entire 46 x 46 inch base. The tank is rated to a 1.9 specific gravity, meaning the wall is engineered to hold liquids up to 1.9 times the weight of water. That is more wall than water storage requires, and it is a genuine capability advantage: the same tank can later handle a denser-than-water fluid, with rated contents reaching roughly 4,754 pounds at the top of that envelope, so a buyer who may store a heavier liquid down the road is already covered. If you are unsure whether 300 gallons matches your draw and refill cycle, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit.

Foundation and installation

A vertical storage tank of this weight belongs on a continuous, level foundation. For a poured pad, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab is sized to the load rather than guessed. In a rural setting this tank can serve as a supplemental or remote-site water reserve; the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection so you can judge how a 300-gallon vertical tank fits alongside larger reservoir capacity rather than assuming it meets a demand-duration requirement on its own. For grey-water, rainwater, or HVAC condensate collection, the industrial water reuse tank topology guide shows how a tank like this fits into a quality-banded storage train.

The mistake to avoid

Do not set a tank this heavy on bare soil, gravel, or a partially supported surface. Uneven bearing under a 2,500-pound-plus water load is the most common cause of stress cracking and premature failure on vertical polyethylene tanks. Give it full, flat, continuous support, and confirm your outlet and fitting locations against the technical drawing on this page before you plumb anything. We can confirm outlet size and bulkhead and gasket fitment by phone before you order, which is far easier than retrofitting connections after the tank is installed.
