The DuraCast 90 Gallon Vertical Liquid Storage Tank (SKU 900090-1.2-BLK) is a compact, black polyethylene tank built for point-of-use water storage where floor space is tight. It stands 63 inches tall on a 23-by-23-inch footprint, so it fits through standard doorways and tucks into corners, utility closets, and equipment sheds that a wider vertical water tank cannot reach. Dimensions are verified.
Will it work for your job?
The tank holds a nominal 90 gallons in a vertical storage configuration. Filled with water it carries 751 pounds, so the pad or platform beneath it has to be flat, level, and rated to support the full load across that 23-by-23-inch footprint. That full-water weight is the number to design around when you are pouring a slab or checking a mezzanine. For a black exterior, siting the tank out of direct interior heat helps keep the stored water cooler. If you are still deciding between capacities, run the numbers through our Tank Sizing Calculator and cross-check against the Tank Sizing Guide before you commit to a footprint.
Foundation and placement
An above-ground vertical tank of this height needs continuous, uniform support under the entire base. Our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that pad right. Check the technical drawing on this page for exact port and base geometry, and if the tank will hold water through freezing weather, plan for freeze protection early rather than after the first cold snap.
The mistake to avoid
Don't treat a slim 90-gallon plastic water storage tank as a chemical vessel by default. This listing covers water and general liquid storage; if you are storing anything with a specific gravity above water or any chemistry beyond plain water, confirm the resin and specific-gravity rating for that service first rather than assuming the black poly wall handles it. Match the tank to the actual liquid, not just the volume.
