The Enduraplas 450 Gallon Black Vertical Water Storage Tank (SKU TLV00450B) is a polyethylene vertical tank built for above-ground bulk water storage where a compact footprint and a tall column of water are the goal. It stands 94 inches tall on a 40 x 40 inch base, holds 450 gallons of water, and the black exterior blocks light to discourage algae growth in stored water. It ships from a single Texas plant in Converse, TX as LTL freight quoted live to your ZIP, so out-of-region buyers should set the freight expectation early.
Will it work for your site?
This vertical water storage tank carries a 1.1 specific gravity rating, which covers water and water-weight contents up to that density. Filled with water, the tank plus contents reaches about 3,753 pounds, and it is rated to carry contents up to roughly 4,128 pounds total. Plan your pad and supports around those numbers, not just the empty tank weight. The 40 x 40 inch footprint keeps the tank's ground area small while the 94-inch height suits transfer and feed setups that want elevation. One caveat: this listing does not specify the outlet or fitting configuration, so confirm port location and size before assuming a bottom-outlet gravity feed. If you are weighing this 450 against other sizes for your draw rate and refill cycle, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide first, and see the technical drawing on this page for dimensional detail.
Plan the foundation and fill before install
A full 450-gallon vertical tank puts thousands of pounds onto a small 40 x 40 inch area, so the slab under it has to carry that load evenly. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting the pad right under a tall, narrow tank like this one. Before you put the tank into service, fill it with water and watch it: our hydrostatic test methodology covers the water-fill discipline, pad settlement monitoring, and fitting leak checks that catch problems on day one rather than month three. For fire-water reservoir duty at rural and remote sites, review the fire-water reservoir design guide for NFPA 22 sizing and cold-climate freeze protection; for grey-water, rainwater, and HVAC condensate aggregation, the industrial water reuse tank topology guide maps where a tank this size fits in a quality-banded storage train.
The mistake to avoid
The common miss on a tank this tall is under-building the foundation. At 94 inches loaded with water, the center of gravity sits high and the entire load concentrates on a 40 x 40 inch base, so a pad that is undersized, unlevel, or settling will stress the tank and its fittings. Get the slab right and confirm the tank holds water cleanly with a hydrostatic test before you trust it. Because the outlet and fitting sizes are not listed here, confirm your fitting and plumbing connection sizes by calling 866-418-1777 rather than assuming a size or a gravity-feed arrangement.
