The Chem-Tainer 2500 Gallon Vertical Liquid Storage Tank is a polyethylene vertical tank built for bulk liquid storage, standing 89 inches tall on a 95 x 95 inch square footprint. If you are sizing a vertical storage tank for water or general non-aggressive liquids and need real capacity in a fixed pad area, this is the workhorse size: 2,500 usable gallons in a single freestanding vessel rated to a 1.5 specific gravity, which gives you headroom well above the weight of water.
Will this tank work for your liquid?
Full of water, this tank carries roughly 20,850 pounds of contents, and the polyethylene shell is rated to hold liquids up to a 1.5 specific gravity, which works out to a maximum rated contents weight near 31,275 pounds. That 1.5 rating is real headroom: a wall engineered for liquids 50 percent heavier than water means plain water storage runs with margin to spare, and you get capacity for heavier fluids - brine, some fertilizer solutions - with no derating for water service. Confirm your liquid's specific gravity falls at or below 1.5 before you commit, and review the technical drawing on this page for the as-built dimensions. If you are unsure how 2,500 gallons fits your draw-down or refill cycle, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide first.
Pad and placement
The 95 x 95 inch (7.9 x 7.9 ft) square base needs a level, fully supporting pad across the entire bottom - plan a slab of at least 9 x 9 feet to leave working clearance for inspection and connection. Run the load math before you pour: 20,850 pounds of water over the 95 x 95 inch base works out to roughly 333 pounds per square foot of floor bearing pressure, climbing to about 500 pounds per square foot at the 1.5 specific gravity ceiling. That is the figure to hand your concrete contractor, and the pad must carry it with no voids or high spots under the tank floor. Confirm the as-built fitting and outlet locations on the technical drawing, and call 866-418-1777 to verify exactly what ships on this SKU before you commit your plumbing run.
Common mistake to avoid
The number people get wrong on a vertical storage tank this size is specific gravity. The 1.5 rating is a ceiling, not a guarantee for every fluid - a denser liquid will overload the wall even when the tank is only partly full. Match your contents to the 1.5 rating, and for anything beyond plain water service, verify the actual specific gravity and chemistry before filling. If you are weighing brands, our Snyder vs Norwesco vs Chem-Tainer vertical storage tank comparison walks through the trade-offs at the adjacent size, and the 2500 gallon buyer's guide covers this exact capacity in depth.
Freight
This 2500 gallon vertical tank ships by LTL freight from the nearest Chem-Tainer plant - Chowchilla, CA for West and Mountain destinations, Griffin, GA for the East and Southeast - and freight is quoted live to your ZIP code. A buyer in Denver will typically draw from Chowchilla while one in Atlanta draws from Griffin, which is why the LTL number tracks with your distance from the closer plant. Get a real figure with our Freight Cost Estimator, or call 866-418-1777 and we will quote the tank and freight together. If this tank is part of a rural fire-water or storage reservoir plan, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection for polyethylene tanks.
