The Chem-Tainer 750 Gallon Vertical Storage Tank is a 750-gallon polyethylene tank built for above-ground bulk water and liquid storage where you need serious volume in a compact 46-inch footprint. Full of water it carries about 6,255 lb of contents - the number your pad has to hold - and it does it in a footprint just 46 x 46 inches. It stands 119 inches tall on that base, molded in Natural White so you can read the fluid level through the wall. The resin carries a 1.5 specific gravity rating, meaning it is engineered to hold contents up to 1.5 times the weight of water, or up to 9,382 lb loaded, giving you real headroom above plain water service.
Will it work for your site?
That contents weight, not the empty tank, is what drives your pad and foundation. On a 46 x 46-inch base (about 14.7 sq ft), a fully loaded 9,382 lb works out to roughly 638 lb per square foot of bearing pressure, so the pad has to be sized for the real load. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. If you are still narrowing down capacity and dimensions, the Tank Sizing Calculator and Tank Sizing Guide help you match volume to your available space and daily draw. The tall vertical profile makes this a strong pick for water storage, rainwater collection, and gravity-fed feed where floor space is tight but headroom is available.
Common uses and sizing notes
As a vertical storage tank, this 750 gallon model fits non-potable water reserves, irrigation supply, and rural fire-water reservoirs where a compact standing tank beats a sprawling low-profile unit. If fire protection is your application, the rural fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For water-reuse setups blending grey-water, rainwater, or HVAC condensate, the industrial water reuse topology guide shows how a standing tank like this fits a quality-banded storage train.
The mistake to avoid
The most common error on a tall vertical tank this size is under-building the foundation. At 119 inches tall and up to 9,382 lb loaded, the tank needs a level, fully supporting pad rated for the actual contents weight, not the water weight - if you plan to store anything heavier than water, size to the 1.5 SG figure and the ~638 lb per square foot it implies. Do not skip anchoring for wind in exposed or elevated sites; a tall, lightly filled tank presents real sail area.
