The Snyder Industries 8900 Gallon Black Heavy Duty Vertical Storage Tank is built for serious bulk water storage where a tall, large-diameter polyethylene reservoir has to hold up under load and outdoor service. It holds 8,900 gallons in a vertical storage tank profile that stands 194 inches (about 16.2 feet) tall on a 120 by 120 inch footprint, which on a round vertical tank means a 10-foot (120-inch) diameter. Knowing the diameter up front lets you plan pad area, doorway and overhead clearance, and containment basin size before it arrives. Molded in black polyethylene, it carries a 1.9 specific gravity rating, the heavy-duty end of the range, meaning the tank wall is engineered for dense contents, not just water. If you are weighing diameter, height, and capacity against your site, the Tank Sizing Calculator and Tank Sizing Guide help you confirm this is the right vertical tank for the volume you need.
Will it work for your site
Sizing this tank is a weight problem before it is a volume problem. Filled with plain water, the contents alone weigh 74,226 pounds, while the tank is rated to a maximum contents weight of 141,029 pounds at its 1.9 specific gravity rating. In other words, water only loads the tank to roughly 53 percent of its rated capacity, so for straight water storage the 1.9 rating is large headroom rather than a requirement, and you are buying margin you may never need to use. Those numbers still drive everything underneath the tank: a 10-foot-diameter vertical storage tank needs a properly engineered foundation, not bare ground. Plan the pad first. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies, so the slab supports the full 120 by 120 inch footprint and the load it carries. For exact outlet, fitting, and manway locations, see the technical drawing on this page, and confirm outlet size, thread type, and gasket material against that drawing before ordering any mating bulkhead fittings or gaskets, since those details are not published in this listing.
What this black tank handles
The black exterior blocks light, which discourages algae growth in stored water and makes this a common choice for fire-water reserves, bulk water, and industrial water service rather than a clear-walled tank where you watch the level through the wall. The 1.9 specific gravity rating gives you margin for water and for denser water-based contents that a standard 1.0 to 1.5 tank would not be rated to hold. If this is going in as a fire-water reservoir, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For reuse trains pulling grey-water, rainwater, or HVAC condensate into bulk storage, the industrial water reuse tank topology guide shows how a tank this size fits a quality-banded storage train.
The mistake to avoid
The most expensive mistake on a tank this size is treating the 1.9 specific gravity rating as license to skip the foundation work. That rating tells you the tank wall can carry dense contents, but it says nothing about what is under it. Set a 141,029-pound maximum load on an undersized or unlevel pad and you risk cracking the slab and stressing the tank, no matter how good the polyethylene is. Confirm the pad to the full footprint and rated weight before you fill. If you need secondary containment, step to a double-wall configuration rather than building a separate basin: the Snyder Captor double-wall freeboard sizing guide explains ASTM D1998 freeboard and the real usable volume after expansion.
At roughly 16 feet tall, this is an over-dimensional move, so it ships LTL freight from the Snyder plant in Lincoln, Nebraska, quoted live to your ZIP, and you will need a forklift or crane on site to offload it. Confirm site access and offload equipment first, get your freight cost with the Freight Cost Estimator, or call 866-418-1777 to talk through access, offload, and lead time for a tank this size.
