The Chem-Tainer 45 Gallon Vertical Storage Tank (SKU TC1851IC-BLACK) is a compact, black polyethylene vertical tank standing 51 inches tall on an 18 x 18 inch footprint. It holds 45 gallons and carries its water high and narrow, which makes it a practical fit for tight equipment rooms, trailers, pump skids, and rural water-storage spots where floor space is limited but you still want vertical capacity. The black color helps limit light penetration and algae growth on outdoor and semi-shaded installs.
Will this tank work for your setup?
This is a polyethylene vertical storage tank rated to a 1.5 specific gravity, so it can carry contents heavier than plain water up to that ceiling. The "IC" in TC1851IC denotes this 1.5-SG (industrial-content) build, so this tank already is the elevated-SG variant rather than a step-down. Filled with plain water (SG 1.0), the tank and contents weigh about 375 lbs; at the full 1.5 SG rating, the maximum contents weight is 563 lbs. In other words, the 1.5 rating is headroom for denser liquids, not a requirement for water service. Key specs:
- Capacity: 45 gallons
- Height: 51 in
- Footprint: 18 x 18 in (18-inch square base)
- Full-water weight: ~375 lb
- Max rated contents weight (1.5 SG): 563 lb
- Material: polyethylene
Because it stacks a tall column of water over a small square base, a level, continuous, fully supporting pad matters for stability, and you should size supports for the loaded weight, not the empty shell. Outlet and fitting configuration is not published for this SKU, so confirm the port layout you need before ordering. To match capacity and dimensions to your actual water demand, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide.
Where it ships from and how freight works
This tank ships by LTL freight, quoted live to your ZIP code. It is stocked at two plants, Bensenville, IL and Hanford, CA, so freight is figured from whichever of those two is nearest you to keep transit time and cost down. Get an exact number with our Freight Cost Estimator, or call 866-418-1777 and we will quote it for you.
The mistake to avoid
The most common misstep on a narrow vertical tank like this is setting it on an undersized or uneven base. An 18-inch square footprint under a 51-inch column of water needs a flat, continuous, fully supporting pad. If you are pouring concrete, our guide on concrete pad sizing for above-ground polyethylene tanks walks through doing it correctly. The second mistake is treating a 45-gallon vertical storage tank like a bulk reservoir: match your pump and piping to a modest working supply. If your project is closer to a fire-water or larger reserve role, our fire-water reservoir design guide shows how to step up correctly.
