The Norwesco 1000 Gallon Doorway Water Tank (SKU N-44045) is built with a narrow doorway profile so you can roll it through a standard door into a basement, equipment room, or other tight opening that a standard vertical tank will never fit. It stores 1,000 gallons in molded polyethylene and carries a 1.5 specific gravity rating, so the wall thickness is engineered for fluids heavier than plain water.
Will it work for your site?
Filled with water, this tank carries roughly 8,340 lb of contents, and its 1.5 SG rating means the shell is rated for a maximum contents weight of about 12,510 lb. That headroom is real capability, not just reassurance: the same tank is rated to store fluids up to 1.5 specific gravity, which keeps brine, some fertilizer solutions, and other denser liquids in scope without overstressing the wall. Size your pad to the case you will actually run. For plain water, confirm the floor or slab can carry the full 8,340 lb load; if you intend to use the full 1.5-SG rating, the pad must carry up to roughly 12,510 lb at full rated contents. Set it on a flat, fully supported surface either way. To compare this 1000-gallon doorway size against the wider 100-to-1000-gallon range, see our Norwesco Doorway Tank Sizing Guide and run the numbers in the Tank Sizing Calculator. The full 1000 Gallon Doorway Water Tank Buyer's Guide walks through application fit in detail.
Dimensions and fittings
For the exact height, width, and fitting layout, see the technical drawing on this page. The narrow doorway profile is the entire point of this Norwesco design: a footprint that passes through doors and tight openings a standard 1000-gallon tank cannot. Before service, confirm that any bulkhead fitting, gasket, and outlet shown on the drawing is rated for your stored fluid and temperature, and call 866-418-1777 to verify the as-shipped fitting package. Use the Tank Sizing Guide to match doorway clearance and floor space at your install point before ordering, so you are not measuring after the truck arrives.
Application fit for a 1000-gallon doorway tank
At 1,000 gallons in a door-passing shape, this tank fits jobs a standard vertical cannot reach. It makes a credible rural or basement fire-water reserve where access is tight; our Fire-Water Reservoir Tank Design guide covers sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC-condensate aggregation in a building footprint, the Industrial Water Reuse Tank Topology guide shows how a tank like this slots into a quality-banded storage train.
Where it ships from and the mistake to avoid
This is a large polyethylene tank, so it ships LTL freight, not parcel. Norwesco molds this size at multiple plants, and we ship from the location nearest you to keep transit and cost down: Lancaster, OH; Shawnee, OK; or St. Bonifacius, MN. Freight is quoted live to your ZIP, never bundled into the list price. The mistake buyers make is fixating on gallons and forgetting the door: the reason to choose this tank is the doorway-clearance shape, so verify the opening it has to pass through and the path to the final location first, then confirm the floor rating for whichever load case applies. Do both and this Norwesco doorway tank drops into spaces a standard vertical tank cannot reach.
