The Chem-Tainer 4500 Gallon Vertical Storage Tank is a black polyethylene vertical tank built for high-volume bulk water storage, standing 156 inches tall on a 95 x 95 inch square footprint. Rated to a 1.5 specific gravity, it holds 4,500 gallons and gives you real headroom for contents denser than plain water. If you are sizing a large vertical storage tank for a farm, fire reserve, or industrial reuse system, this black tank is one of the larger single-vessel options in the Chem-Tainer vertical storage line.
Key specifications
- Capacity: 4,500 gallons
- Dimensions: 95 in diameter footprint x 156 in tall
- Material / color: Polyethylene, black
- Specific gravity rating: 1.5
- Weight full of water: ~37,530 lb | Max rated contents: 56,295 lb
Will it work for your site?
Filled with water at roughly 8.34 lb per gallon, this tank carries about 37,530 lb of contents when full. At its full 1.5 specific gravity rating those contents can weigh up to 56,295 lb, so plan your foundation for the density of what you actually store. That combined load is why the pad matters as much as the tank: a 95 x 95 inch footprint concentrates a lot of weight on a small ground area. Read our concrete pad sizing guide before you pour, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm this capacity matches your draw and refill cycle. The black wall blocks light, which discourages algae growth in stored water compared with lighter translucent walls. Fitting configuration (outlet, fill, and vent sizes) is confirmed by phone before order rather than assumed, so call 866-418-1777 to spec the penetrations you need.
Common uses
At 4,500 gallons on a compact vertical footprint, this storage tank fits non-potable bulk water storage, rainwater and greywater collection, and rural fire-water reserves where a large volume has to sit in a tight area. If you are engineering a private fire-protection reserve, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For reuse systems that band grey-water, rainwater, and HVAC condensate together, our water reuse topology guide walks through storage-train sequencing. Comparing brands at a given capacity?

The mistake to avoid
Do not undersize your foundation by planning around water weight alone. This tank is rated for a 1.5 specific gravity, and if you store anything denser than water the load climbs toward 56,295 lb. Size the pad and any anchoring for the density of your actual contents, not a generic water figure.
At 156 inches tall on a 95-inch footprint, this 4,500-gallon tank ships as a standalone oversize LTL freight item from Hummelstown, PA, quoted live to your ZIP.
