The Chem-Tainer 75 Gallon Black Vertical Water Storage Tank is a compact polyethylene vertical tank built for water storage where floor space is tight. It holds 75 gallons in a 23-inch by 23-inch footprint and stands 49 inches tall, so it fits in a corner, a utility room, a trailer, or a pump shed without taking over the space. The black color blocks light, which helps suppress algae growth in standing water. This tank carries a 1.0 specific gravity rating, meaning it is engineered for the weight of water and water-weight liquids - not heavier chemical solutions.
Will this tank work for my job?
Filled to capacity, 75 gallons of water weighs 626 pounds, which is also the maximum rated contents weight for this tank. Plan your stand, platform, or pad for the full 626-pound load, not just the empty shell. Note that 626 pounds rides on a 23-by-23-inch base while the tank stands 49 inches tall, so the center of gravity sits relatively high for the footprint - set it on a level, fully supported surface, and in trailer or mobile service restrain it against shifting. The 23-by-23-inch footprint is the number that matters when you are laying out a pump skid or sizing a concrete pad. If you are weighing this 75-gallon size against other capacities, run your numbers through our Tank Sizing Calculator and review the Tank Sizing Guide to match volume, footprint, and fill weight to your space.
Ports, plumbing, and what to confirm
Outlet and fill-port size and placement are not published in our spec data for this SKU, so confirm them against the technical drawing on this page or call us at 866-418-1777 before you plumb the tank. This is a vertical water storage tank, suited to general water storage, rainwater capture, water reuse, and standby reserve. The most common mistake at this 1.0 specific gravity rating is using the tank for liquids heavier than water. The 1.0 rating and the 626-pound maximum contents weight are tied together: a denser liquid would exceed the wall design at the same fill level. For liquids heavier than water, call 866-418-1777 or use the Tank Sizing Guide to select a higher specific-gravity industrial tank. For larger vertical builds, our Snyder vs Norwesco vs Chem-Tainer 2000 Gallon vertical comparison shows how brand and wall thickness scale up, and if this tank feeds private fire protection, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
Mounting and pad considerations
Because the entire 626 pounds of filled weight rides on that 23-by-23-inch base, the supporting surface does real work. For permanent above-ground installs, our concrete pad sizing guide lays out the ACI 360R-10 framework so the pad carries the load without cracking or settling. If you are aggregating grey-water, rainwater, or HVAC condensate across multiple tanks, the industrial water reuse topology guide shows how to band quality and sequence storage trains.
