The Chem-Tainer 500 Gallon Vertical Storage Tank (SKU TC6446IC-BLACK) is a black polyethylene vertical storage tank built to hold bulk water on a compact footprint. It stands 46 inches tall on a 64 x 64 inch base, so a full 500-gallon fill sits low and stable rather than tall and tippy. If you have been searching for a 500 gallon tank or a black vertical storage tank for water service, this is the size and shape that tucks under most enclosures and against a wall without the height a taller vertical demands.
Will it work on your site?
Plan the pad around the full-water figure, not the empty shell. At 500 gallons of water this tank carries roughly 4,170 lb of contents spread across the 64 x 64 in footprint, so size your slab and any tie-downs to that loaded number. Run your fill volume through our Tank Sizing Calculator and review the Tank Sizing Guide before you set the base. One detail worth confirming up front: outlet and bulkhead-fitting configuration is shown on the manufacturer drawing on this page, so verify the outlet size and location before you order gaskets or bulkhead fittings rather than assuming a thread size.
Rated to 1.5 specific gravity
This tank is rated to a 1.5 specific gravity, which puts its maximum rated contents weight at about 6,255 lb versus the 4,170 lb of a full water fill. For a water buyer that rating is the real advantage: the wall is over-built for plain water, which means a long service margin, and it is the same shell that would handle heavier 1.5-SG liquids if your service ever changes. Note that the 6,255 lb figure only applies at that higher gravity, so keep your slab and tie-down math anchored to the 4,170 lb full-water load for a water install.
Set it on the right base
A vertical poly tank of this weight needs a flat, fully supporting foundation. Pour or level a base that carries the entire 64 x 64 in footprint with no unsupported overhang, because the most common mistake on a tank this size is undersizing the support and letting an edge hang past the slab, which stresses the wall over time. If you are placing this tank on a poured slab, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting the pad right the first time. For rural fire-water reserves and water-reuse setups where headroom is limited, our field guides on fire-water reservoir tank design and industrial water reuse tank topology help you fit this size into a larger storage train.
