The 750 Gallon Black Heavy Duty Vertical Storage Tank from Snyder Industries (part number SII-1008500C34) is a polyethylene vertical storage tank built for serious bulk water duty. It stands 50 inches tall on a 72-inch diameter footprint and holds 750 gallons behind a 1.9 specific gravity rating - meaning the wall is engineered for contents far denser than water, giving you real margin when this tank stores water day in and day out.
Will it work for your site?
Filled with water, this tank carries roughly 6,255 lbs of contents, while its 1.9 SG wall is rated to hold as much as 11,884 lbs of contents at maximum density - about 1.9 times the weight of a full water load. For a water application that is a wide safety margin, which is exactly what you want in a tank feeding a fire reserve, an irrigation line, or a rural water supply that has to sit full for long stretches. Just remember that 11,884 lb figure is a weight-of-contents rating tied to specific gravity, not a burst or structural guarantee. The short-and-wide 72-inch diameter, 50-inch tall profile keeps the center of gravity low and the footprint stable - a better fit for low-clearance buildings and pump houses than a tall, narrow vertical of the same capacity. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm this 750-gallon vertical tank matches your draw-down and refill cycle before you order.
Set it on the right foundation
A full vertical storage tank at this weight needs a flat, fully supporting pad. Plan for a 72-inch-diameter circular footprint - a full 6 feet across - on the slab. Poly tanks transfer their entire load straight down through the floor, so the pad has to carry the base evenly with no voids or high spots underneath. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that foundation right the first time. If this tank is going into a private fire-protection reservoir, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
The mistake to avoid
The most common misstep on a heavy-duty vertical like this one is confusing the wall rating with a chemical clearance. The 1.9 SG rating tells you the wall can carry dense contents by weight - it does not by itself qualify the tank for a specific chemical. This unit is spec'd here for water storage. Fitting sizes and outlet locations are confirmed at order, so refer to the technical drawing on this page for outlet detail before you plumb it in, and match your gasket or o-ring material to your fluid. If you are planning anything other than water, confirm the resin and gasket materials against the OEM chemical-resistance chart first.
