The Norwesco 950 gallon heavy duty vertical storage tank is built for operators who need bulk water capacity in a compact footprint. At 134 inches tall on a 48 by 48 inch base, this light blue polyethylene tank holds 950 gallons while occupying just four feet square of pad space, which makes it a practical choice when vertical room is available but ground area is tight. The tank carries a 1.9 specific gravity rating, so it is engineered to handle heavier-than-water contents, not just plain water storage.
Will this tank work for your site?
Filled with water at 8.34 pounds per gallon, a full 950 gallon tank weighs roughly 7,923 pounds. Because the wall is rated to a 1.9 specific gravity, the maximum rated contents weight runs to about 15,054 pounds. Put another way, this same tank handles liquids up to roughly 15.8 pounds per gallon, covering many concentrated solutions a 1.0-SG water-only tank cannot, so you can repurpose it for denser service later without buying a heavier-walled tank. That weight matters for your foundation: a fully loaded tank concentrates over seven and a half tons onto a 48 by 48 inch footprint, so it needs a level, continuously supported concrete or engineered pad. Confirm fitting size, location, and the correct gasket material from the technical drawing on this page before plumbing, since gasket selection must match both the contents and the 1.9 specific gravity rating. For help confirming the right capacity and pad load for your application, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit.
Common applications and sizing
This is a standard Norwesco vertical storage tank, the workhorse format for rural and commercial water programs. The compact base makes it a strong fit for fire-water reserves on remote sites, agricultural and irrigation supply, rainwater capture, and industrial water reuse trains. If you are planning a private fire-protection reservoir, our guide on fire-water reservoir tank design and NFPA 22 sizing discipline walks through reserve sizing and freeze protection for cold-climate service. For rainwater capture, our guide on first-flush diverter sizing per the Texas Manual on Rainwater Harvesting covers the inflow side, and for multi-source water capture and quality-banded storage, see our piece on industrial water reuse tank topology.
Pad and foundation
Do not skip the foundation step on a tank this size. The single most common and costly mistake with tall vertical tanks is setting them on uneven or undersized support: at 134 inches of height and over 7,900 pounds when full of water, any settlement or point loading under the base can stress the tank wall. Pour a flat, fully bearing pad sized to the load. Plan for the full 134 inch height plus fill and vent clearance overhead, and a 48 by 48 inch pad footprint, when siting under eaves, in containment, or inside a building. Our walkthrough on concrete pad sizing for above-ground polyethylene tanks covers the ACI 360R-10 framework and where the ACI 318 boundary applies.
Freight and ordering
This tank ships LTL freight from Fairfield, TX, with the cost quoted live to your ZIP code. Because a 134 inch vertical tank is an oversize freight item, use our Freight Cost Estimator for a freight quote to your destination, or call us at 866-418-1777 and we will confirm freight, lead time, and the best fit for your storage program before you order.
