The 10500 Gallon Vertical Liquid Storage Tank (Norwesco, SKU N-47638) is a white polyethylene bulk-storage tank built for high-volume above-ground water service. It stands 202 inches tall on a 130-by-130-inch footprint, and its 1.5 specific gravity rating means it is engineered to hold liquids heavier than plain water. At full water capacity it carries 87,570 pounds, and the shell is rated to a maximum contents weight of 131,355 pounds. For sites that need serious storage volume in a single vertical footprint, this tank concentrates a large rated capacity into a compact ground area.
Will this tank work for your site?
With 10,500 gallons rising to 202 inches over a 130-by-130-inch footprint, this Norwesco vertical storage tank packs large volume into a compact pad area, which matters when you're laying out a tank yard or containment area. Treat the 130 x 130 inch figure as the overall envelope footprint rather than a precise cylinder diameter, so your pad layout accounts for the base flare. The 1.5 specific gravity rating is the number to check first: it tells you the wall is built to stand up to liquids weighing up to 1.5 times water. The spread between the full water weight of 87,570 pounds and the maximum rated contents weight of 131,355 pounds gives you real headroom for denser fluids, but always size to the actual specific gravity of what you're storing. Use the Tank Sizing Calculator to confirm the volume against your drawdown and refill needs, and the Tank Sizing Guide if you're deciding between this and a smaller vertical.
The 1.5 SG headroom, and when you need more
That 1.5 specific gravity wall rating is what lets this tank safely hold heavier-than-water fluids up to 1.5 times water density. If your liquid exceeds 1.5 SG, this is not the right unit and you need a higher-SG-rated tank instead. Rather than guess, run your fluid's specific gravity through the Tank Sizing Calculator or call our team at 866-418-1777 and we'll help you spec a tank rated for it. For fitting locations and outlet placement, see the technical drawing on this page and confirm the connections match your plumbing, and match your bulkhead fittings and gaskets to the port size and service before installation.
Foundation and common uses
A tank this size lives or dies on its foundation. At 131,355 pounds fully loaded across a 130-by-130-inch footprint, the pad has to be engineered, level, and continuous under the full base. Our guide on concrete pad sizing for above-ground polyethylene tanks covers the ACI 360R-10 framework and where the ACI 318 boundary applies, so the slab is right before the tank arrives. This capacity class shows up in rural and remote fire-water reservoirs, industrial process water, and large-scale water reuse. If fire protection is your driver, the guide to fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For grey-water, rainwater, and HVAC condensate aggregation, the industrial water reuse tank topology guide maps out quality-banded storage trains and treatment sequencing.

This Norwesco vertical storage tank ships LTL freight from the Albertville, Alabama plant, quoted live to your ZIP. Because it's an oversized unit, get a real number before you commit: run your delivery address through our Freight Cost Estimator or call 866-418-1777 and we'll quote it and coordinate the offload. A tank this large needs the right equipment on site to receive it, so let's plan the delivery together.
