The Norwesco 3000 Gallon Plastic Water Storage Tank (SKU N-40635) is a black vertical water tank measuring 95 inches in diameter and 109 inches tall, molded from polyethylene for indoor and outdoor bulk water storage. The black resin blocks sunlight, which suppresses algae growth in stored water and makes this a practical choice for rural water systems, fire-water reserve, irrigation supply, hauled-water staging, and rainwater or grey-water collection. If you are matching tank volume to your demand, the Tank Sizing Calculator and Tank Sizing Guide walk you through it.
Will it work for your site?
This is a vertical storage tank rated for water at a specific gravity of 1.0. Filled to its full 3000-gallon capacity, the contents weigh 25,020 pounds, which is also the maximum rated contents weight. That load sits on a 95-inch-diameter footprint, so the numbers your pad contractor needs are simple: 95 inches diameter, 109 inches tall, 25,020 pounds full. Plan the base accordingly. A vertical poly tank of this size needs continuous, uniform support under the entire bottom; the slab or compacted ring must be level, full-diameter, and engineered to carry that weight without settling. Bridging across a soft spot or setting it on an undersized ring is the most common cause of stress cracking. Confirm fill, draw, and overflow fitting locations against the technical drawing on this page before you set the tank, since those positions determine where your plumbing lands.
Black resin and SG 1.0 — read this before you buy
The mistake to avoid on this tank is putting anything other than water-weight liquid in it. The 1.0 specific gravity rating means it is built for water and water-density liquids only; heavier liquids exceed the structural rating and are not appropriate here. This is a water storage tank, so keep it on water service. The black color is the right call for stored water where you want to discourage algae, but if you specifically need a light-transmitting wall to gauge level by eye, the 3000-gallon natural-white vertical version is the variant to look at instead. For fire-protection reserves, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and freeze protection for cold-climate sites, and if you are aggregating grey-water, rainwater, or HVAC condensate, the industrial water reuse topology guide covers banded storage trains and treatment sequencing.
