The Norwesco 1700 Gallon Vertical Liquid Storage Tank is an 87-inch-diameter, 74-inch-tall polyethylene tank built for bulk above-ground water and liquid storage. It carries a 1.5 specific gravity rating, so it is engineered to hold contents heavier than water up to that density, and its broad 87-inch footprint keeps a full load low and stable. Filled with water it holds roughly 14,178 pounds, and at its maximum 1.5 SG rating the contents reach about 21,267 pounds, numbers that drive every decision below it: pad, plumbing, and freight.

Will it work for your site?
This vertical storage tank is sized for fresh-water reserves, irrigation supply, rural fire-water reservoirs, rainwater aggregation, and general industrial liquid storage. The 87-inch diameter against the 74-inch height gives it a wide, squat profile that resists tipping and simplifies siting under most roof lines and inside many buildings. Fitting configuration on a vertical tank this size varies by unit, so review the technical drawing on this page and call 866-418-1777 to confirm outlet, fill, and vent placement before you plumb your suction and fill lines. If you are weighing this size against your actual draw and refill needs, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.
Foundation and weight planning
The full-water weight of about 14,178 pounds, and up to roughly 21,267 pounds at the 1.5 SG limit, means the pad does the real work here. A vertical tank this size needs a level, continuously supported foundation rated for that load. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab matches the loaded weight rather than the empty shell. If your application is rural fire protection at this capacity, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and cold-climate freeze protection, and if you are banding storage by quality, the industrial water reuse topology guide covers grey-water, rainwater, and HVAC condensate aggregation.
The mistake to avoid
The 1.5 specific gravity rating is a ceiling, not a target. It tells you the tank wall is built to carry liquids up to 1.5 times the weight of water, but pouring in a denser liquid than that, or undersizing the pad for the loaded weight, is where these installs go wrong. Plan the foundation around the 21,267-pound maximum, not the empty tank, and verify your contents stay at or below the 1.5 SG rating. A complete walkthrough of this specific size lives in the 1700 Gallon Vertical Liquid Storage Tank buyer's guide.
