The Norwesco 10500 Gallon Black Heavy Duty Vertical Storage Tank is one of the largest polyethylene vertical tanks in the Norwesco lineup, holding 10,500 gallons inside a 130-inch diameter footprint that stands 202 inches tall. Molded from heavy-duty black polyethylene and carrying a 1.9 specific gravity rating, this is a Norwesco vertical storage tank built for serious bulk water and heavy-liquid storage where a smaller vertical tank would force you into multiple vessels and extra plumbing.
Will it hold what you need it to?
At full capacity of fresh water (specific gravity 1.0), the contents alone weigh about 87,570 pounds. The 1.9 specific gravity rating is the spec that separates this from a plain water tank: the wall is built to safely carry liquids substantially heavier than water - brine, dense process liquids, and heavy slurries by gravity - up to a maximum rated contents weight of roughly 166,383 pounds. That is the headroom that makes this a workhorse rather than a water-only vessel. Match your real liquid to your capacity with our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a size.
Dimensions, foundation, and siting
The footprint is 130.0 x 130.0 inches - roughly a 10.8-foot square pad - with an overall height of 202 inches, about 16.8 feet. That height exceeds standard door and canopy clearances, so this is an outdoor tank that needs crane or boom access for delivery and for routing fill lines and vents up top. The most important number on a tank this size is the loaded weight your pad and anchoring must carry, and it is a wide range: from roughly 87,570 pounds with water up to about 166,383 pounds at the full 1.9 SG rating - a swing near 79,000 pounds. Design the foundation to the actual liquid you will run, not the empty tank and not water if you are storing something denser. Our guide on Concrete Pad Sizing for Above-Ground Polyethylene Tanks walks through the ACI 360R-10 framework and the ACI 318 boundary so the pad matches the loaded mass. See the technical drawing on this page for outlet and fitting locations referenced to the tank base.
Fittings, fit, and the mistake to avoid
Outlet and bulkhead configuration on a tank this large is confirmed at quote time - call 866-418-1777 to verify the available outlet and bulkhead sizing for your application before you order, so the plumbing you plan matches what ships. The most common mistake on a 10,500-gallon vertical is under-building the pad or skipping anchoring: the 1.9 SG rating protects the tank wall, but the foundation has to carry the full loaded weight you actually run. For high-volume rural and remote water reservoirs, our write-up on Fire-Water Reservoir Tank Design for Rural and Remote Sites covers NFPA 22 reserve sizing and cold-climate freeze protection, and for grey-water, rainwater, and HVAC condensate aggregation at this scale, see Industrial Water Reuse Tank Topology.
This Norwesco vertical storage tank ships LTL freight from the Albertville, AL plant, quoted live to your ZIP - East and Southeast destinations will see materially lower freight than far-West ZIPs on a tank this size, so price your own location with the Freight Cost Estimator before you commit.
