Chem-Tainer 500 Gallon Vertical Storage Tank

The Chem-Tainer 500 Gallon Vertical Storage Tank (SKU TC4676IC-BLACK) is a black polyethylene vertical tank built for straightforward bulk water storage. It stands 76 inches tall on a 46 x 46 inch footprint, so it fits a compact pad while holding a full 500 gallons. This is one of the workhorse sizes people search for when they want a 500 gallon vertical storage tank that stores reliably and installs without a crane.

Will it work for your site?

Filled with water, this tank carries about 4,170 pounds of contents, and its 1.5 specific gravity rating means it is engineered to hold liquids up to 6,255 pounds at full volume. That SG headroom is why the same shell serves both plain water and denser liquids without stressing the wall. The quick spec check most buyers make against a pad drawing:

• Height: 76 in
• Diameter / footprint: 46 x 46 in
• Full water weight: ~4,170 lb
• Max rated contents (1.5 SG): 6,255 lb

Before you set it, plan the pad for the loaded weight, not the empty tank. To confirm this size matches your demand and refill cycle, run the numbers with our Tank Sizing Calculator and read the Tank Sizing Guide.

Siting and pad

A vertical storage tank this tall wants a level, fully supporting foundation across the entire base. Poly tanks flex under load and need continuous bearing, not point supports. Size the pad to the loaded footprint and design it for the full contents weight; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework. If this feeds a rural fire-water reservoir or remote water supply, the fire-water reservoir design guide covers freeze protection and NFPA 22 sizing discipline, and 500 gallon tanks are a common building block when several are combined for a larger reserve.

The mistake to avoid

The common miss on a 1.5 SG vertical tank is undersizing the foundation or setting it on uneven ground. The wall rating protects the tank; the pad protects your installation. Build the base for the loaded weight and keep it dead level, and confirm the black exterior suits your placement, since the opaque color limits interior level visibility compared with a translucent shell.
