The Chem-Tainer 750 Gallon Vertical Storage Tank (SKU TC750XIC-BLACK) is a black polyethylene vertical storage tank built in the classic tall-and-narrow format: 119 inches of height over a compact 46 x 46 inch footprint, rated to a 1.5 specific gravity. That SG number is the first thing to check. It means the wall is engineered to hold contents up to 50 percent heavier than water, so while a full 750 gallons of water weighs about 6,255 pounds (roughly 3.1 tons), the tank is structurally rated to carry up to 9,382 pounds of contents at its full 1.5 SG ceiling (about 4.7 tons). For plain water storage, that gap is your headroom — you are running the shell well below its rated load, which is exactly what you want in a long-service vertical tank.
Will it work for your site?
The tall, small-footprint geometry makes this tank a strong fit where floor space is tight but overhead clearance is not. Confirm your install area can accommodate the full 119-inch height plus any top fittings before ordering, and verify overhead clearance in barns, pump houses, or covered enclosures. Because the loaded tank carries roughly 3.1 tons of water, it needs a flat, fully supporting foundation across the entire 46 x 46 inch base — a properly sized concrete pad is the right call. Our concrete pad sizing guide walks through the ACI framework for above-ground polyethylene tanks. If you are still settling on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to demand.
Fittings and configuration — confirm before you order
The inlet, outlet, vent, and lid configuration for this SKU is not specified in our catalog data. Do not assume a particular bulkhead, outlet size, or lid opening — confirm the exact fitting layout and lid size with us at 866-418-1777 before ordering so the tank arrives ready for your plumbing. You can review the port arrangement on the technical drawing on this page as well.
Common uses and sizing
A black 750 gallon vertical storage tank is a workhorse for rural and remote water storage, agricultural supply, rainwater collection, and fire-water reservoir duty. The black color limits light transmission, which helps discourage algae growth in stored water. For private fire protection planning, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service, and if you are aggregating grey water, rainwater, or HVAC condensate, the industrial water reuse topology guide is worth a read.
The mistake to avoid
The biggest error on a tank this size is treating it as freestanding or setting it on soil, gravel, or a partial support. A tall vertical tank holding roughly 6,255 pounds of water develops real hydrostatic load at the base; it must sit level and fully supported on a pad that carries the entire footprint, or the shell can distort over time. The second error is reading the 1.5 SG rating as a chemical clearance — it is a structural weight limit, nothing more. If you plan to store anything other than water, chemical service depends on both that 1.5 SG ceiling and the fitting and gasket materials (EPDM versus Viton/FKM), and those gasket details are not in this record — confirm them with us before switching service.
