The Norwesco 1100 Gallon Above Ground Tank ships in white polyethylene, standing 86 inches tall on a square 78 x 78 inch footprint - a compact-footprint choice for above-ground water storage where vertical height is easier to accommodate than sprawl. Note one thing up front: the catalog name carries a "sphere" label, but the geometry here is a standard vertical round tank (78 in diameter, 86 in tall), not a spherical vessel. It carries a 1.5 specific gravity rating, meaning the wall is built to hold contents heavier than water - genuine headroom even on a straight water job. If you are weighing this against other 1100-gallon Norwesco vertical tanks, footprint and height clearance at your install point are the specs that decide the buy.
Will it work for your site?
Key dimensions: 86 in H x 78 in dia, 78 x 78 in footprint. Check that against your door, gate, ceiling, and overhead clearance before delivery - an 86-inch tank is the kind of height that surprises people at the install point. Filled with water, this round tank carries roughly 9,174 pounds of contents; at its full 1.5 specific gravity rating it is engineered to hold up to 13,761 pounds. That 1.5 rating is the quiet differentiator on this Norwesco vertical tank: if your storage need ever moves to a liquid denser than water, the tank already has the structural headroom, so you are not re-buying later. Run your volume and refill math through the Tank Sizing Calculator, and if you are deciding between capacities, the Tank Sizing Guide walks through how height, footprint, and weight trade off.
Foundation, pad, and fittings before delivery
The most common mistake on a tank this size is setting it on a pad that was never sized for the load. Roughly 9,174 pounds of water on a 78-inch circle of polyethylene will find every soft spot, every crack, and every slope, so the surface underneath has to be flat, level, and continuously supported across the entire base. Get the base right before the truck arrives: our guide on concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework so the pad supports the full footprint rather than bridging across it. For rural and remote water storage - fire reserve, well buffer, or off-grid supply - the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate polyethylene service. On fittings: confirm the inlet, outlet, and lid configuration from the technical drawing on this page or by phone before you plan plumbing - we do not publish fitting sizes we cannot verify for your exact unit.
Freight and ordering
This Norwesco vertical tank ships LTL freight from Hanford, CA - the nearest plant to most West Coast jobs - with the cost quoted live to your delivery ZIP. Tank freight is rated by size and distance, not bundled into the listed price, so get a real number for your address with the Freight Cost Estimator before you order, or call 866-418-1777 and we will quote it and confirm delivery details for a round tank this tall. If you are cross-shopping similar Norwesco vertical tanks, compare this one against the taller, slimmer 1100-gallon builds: the 1100-gallon vertical tank (part 42591, 53 in dia x 87 in) and the 1100-gallon vertical tank (part 40070, 53 in dia x 87 in). Choose the narrower 53-inch footprint if floor space is tight, or this 78-inch footprint if height clearance is the constraint.
