The Norwesco 1000 Gallon Plastic Water Storage Tank (SKU N-41500) is a black vertical water tank measuring 64 inches in diameter and 81 inches tall, molded from polyethylene with a specific gravity rating of 1.0. It holds 1000 gallons of upright bulk water storage on a compact 64-inch round footprint, so you get real capacity without a wide pad. The black exterior blocks light to discourage algae growth, which makes it a practical pick for rainwater collection, livestock supply, irrigation, and rural fire-water reserve.
Will it work for your site?
A full tank of water weighs about 8,340 pounds. Spread across the 64-inch round floor (roughly 3,200 square inches), that works out to an average pad bearing of about 2.6 pounds per square inch - the number your concrete or pad contractor actually wants. This vertical storage tank needs a level, fully supported base: poured concrete or compacted, screened sand graded flat, sized to carry the entire 64-inch diameter. Polyethylene flexes under load, so any gap or high spot beneath the floor concentrates stress and can crack the wall over time. Confirm your stand, slab, or ring foundation can carry more than four tons before filling. To match capacity to your draw-down and refill cycle, use our Tank Sizing Calculator and the Tank Sizing Guide.
Specs and configuration
Rated specific gravity: 1.0 (water and water-weight liquids only; 8,340 lb maximum rated contents). That single line ties the service limit and the weight limit together - they are the same fact. This tank is not built for denser chemical contents. For molded port locations, refer to the technical drawing on this page for the inlet, outlet, and lid placement before you plumb the tank, so your bulkhead and manifold runs line up. Because this is an 8,340-lb-capacity tank set by the LTL driver, confirm the fitting positions against the drawing before the truck arrives, not after the tank is on its pad - returns on a tank this size are impractical.
The mistake to avoid
The most common error with a tank this size is treating it like a chemical vessel. It is rated at a specific gravity of 1.0 - water. Filling it with a denser liquid exceeds the wall's design load and voids its rating. The second mistake is an undersized or unlevel foundation; the full water weight of roughly 8,340 pounds must sit flat and fully supported across the whole 64-inch diameter. Need lower overall height or a wider base instead? A same-capacity 1,000-gallon black 72-inch diameter by 66-inch tall variant exists - see its buyer's guide to compare footprint against height. If this tank is part of a rural fire-protection reserve, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and cold-climate freeze protection; for reuse setups, see our guide on industrial water reuse tank topology. A full model walk-through for this 64 x 81 tank lives in our complete buyer's guide.
