The Norwesco 8400 Gallon Black Heavy Duty Vertical Storage Tank gives you 8,400 gallons of bulk capacity on a 120-inch (10-foot) diameter footprint, standing 15 feet 7 inches (187 in) tall. Molded from polyethylene in black to shade contents from UV and slow algae growth, it carries a 1.9 specific gravity rating, meaning the wall is engineered to hold liquids up to 1.9 times the weight of water. For water storage, agricultural supply, fire-water reservoir duty, and industrial storage, that 1.9 rating leaves substantial reserve margin over water's 1.0.
Will it work for your site?
Plan around the numbers before you pour a pad. Filled with water this vertical storage tank carries roughly 70,056 lb, and its 1.9 rating allows a maximum rated contents weight near 133,106 lb. Read those two figures correctly: the 133,106 lb only applies if you are storing a liquid up to 1.9 SG, so for plain water service your pad design load is the ~70,056 lb water weight plus the tank and appurtenance weight, not the higher number. That load rides on a 120.0 x 120.0-inch footprint, so the pad and its subgrade must be designed for the point loading, not just the tank diameter. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm this Norwesco tank fits your volume and headroom, and see the technical drawing on this page for full dimensional detail. Freight-wise, it ships from Albertville, AL for East and Southeast lanes or Fairfield, TX for Central and Southwest lanes, so you can estimate your route before quoting.
Pad and foundation
At six figures of pounds when fully loaded to its rating, this vertical storage tank belongs on an engineered, level, fully supporting concrete pad. 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. If this tank is going into rural fire protection, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection for cold-climate service. Storing reclaimed or harvested water? The industrial water reuse topology and rainwater harvesting guides help you band and stage your storage train.
Common mistake to avoid
The biggest error on a tank this size is under-building the foundation. A 10-foot-diameter poly tank does not bridge soft spots or slope; any voids or settlement under the base transfer directly into the tank wall. Get the pad flat and continuously supported before delivery day, and verify your access route and any overhead clearance can accept a tank that stands 15 feet 7 inches (187 in) tall.
This Norwesco vertical storage tank ships by LTL freight from the nearest plant to you, either Albertville, Alabama or Fairfield, Texas, with freight quoted live to your ZIP.
