The Chem-Tainer 1150 Gallon Vertical Storage Tank is a black polyethylene vertical built on a 48 x 48 inch footprint and standing 156 inches tall. Rated to a 1.5 specific gravity, it holds denser contents than a standard 1.0-rated water tank, which makes it the heavier-duty pick for bulk water storage, fire-water reservoirs, rainwater capture, and heavier fluid duty where a plain water-only tank would be under-spec'd. Its black color is a neutral spec here, not a water-quality claim.
Will it work for your site?
Confirm three things before you order. First, headroom and stability: at 156 inches on a 48 inch footprint this is a tall, narrow vertical (a roughly 3.25:1 height-to-width profile), so plan for a level pad plus anchoring or tie-downs for wind and seismic exposure, not just clearance overhead. Second, weight and the pad it dictates: filled with water the contents weigh about 9,591 lb, and the 1.5 SG rating means it can legally hold contents up to roughly 14,386 lb, about 1.5x the water fill. A flat, continuously supported concrete pad is the right foundation at that load, and our concrete pad sizing guide walks through the ACI framework for above-ground poly tanks. Third, capacity: if you are still choosing sizes, run the numbers with our Tank Sizing Calculator or read the Tank Sizing Guide. For rural fire-protection duty, the fire-water reservoir design guide covers NFPA 22 reservoir sizing and cold-climate freeze protection.
Fittings and configuration
Check the fitting layout on the technical drawing on this page for outlet and fitting sizes and placement before you plumb the tank. Match your bulkhead fitting, gasket, and valve sizes to the ports shown there rather than assuming a standard size, and for 1.5 SG heavier-than-water service spec gaskets rated for the actual fluid, not just water. If you are comparing this Chem-Tainer against other brands at a larger size, our Snyder vs Norwesco vs Chem-Tainer comparison shows how the three lines stack up. Reusing captured supply? The industrial water reuse topology guide covers grey-water, rainwater, and HVAC condensate storage trains.
The mistake to avoid
Do not under-build the foundation. Buyers size the pad for the empty or water-filled tank and forget that a 1.5 SG rating means it can hold contents far heavier than water. Set your pad and anchoring for the roughly 14,386 lb max rated contents weight, not the 9,591 lb water fill, and you will not fight settling or cracking later.
