The Norwesco 11000 Gallon Plastic Water Storage Tank (SKU N-44013) is a large-format vertical polyethylene tank built for bulk water storage where capacity matters more than footprint. It stands 167 inches tall (about 13.9 feet) on a 144-inch (12-foot) diameter base, holding 11,000 gallons in a single upright cylinder. If you are sizing a vertical storage tank for rural fire-water reserve, agricultural supply, industrial process water, or rainwater and reuse aggregation, this is a high-capacity option in the Norwesco water storage line.
Will it work for your site?
The tank is molded from polyethylene and carries a 1.0 specific gravity rating, which is correct for water. That rating is also a boundary: this tank is rated for fluids up to 1.0 SG only, so it is sized for plain water, not heavier chemical service. Filled to capacity it holds 91,740 pounds of water, and its maximum rated contents weight is the same 91,740 pounds. That number drives every siting decision. The footprint is a 144.0-inch diameter circle, and at roughly 14 feet of vertical height you also need overhead clearance for fill and access hardware. To match tank volume to your demand profile, use the Tank Sizing Calculator or read the Tank Sizing Guide.
Confirm fittings on the technical drawing
Fitting and lid configuration is not recorded in our spec data for this SKU, so do not assume an outlet size, bulkhead location, or manway position from the listing. The technical drawing on this page is the authority: verify inlet and outlet sizing, fitting placement, and overall dimensions there before you order or pour a pad. If you need confirmation on a specific fitting for your plumbing layout, call 866-418-1777 and we will check it against the manufacturer drawing.
The mistake to avoid: under-building the pad
The single biggest error on a tank this size is skipping the foundation engineering. At 91,740 pounds full, a settled or uneven pad will stress the tank wall and fittings. A vertical poly tank of this scale needs a properly sized, level, fully supporting concrete pad carrying the entire 12-foot load circle. Our guide on Concrete Pad Sizing for Above-Ground Polyethylene Tanks covers the ACI 360R-10 framework and where the ACI 318 boundary applies. Before commissioning, follow a disciplined fill and acceptance procedure; the Hydrostatic Test Methodology for New-Install Tank Acceptance covers water-fill discipline, pad settlement monitoring, and fitting leak detection.
Common uses for an 11,000-gallon vertical tank
At this volume the tank earns its place as a rural fire-water reservoir; see Fire-Water Reservoir Tank Design for Rural and Remote Sites for NFPA 22 sizing discipline and cold-climate freeze protection. It also works as the storage heart of an industrial water reuse train, aggregating grey-water, rainwater, and HVAC condensate into quality-banded storage.
