The Norwesco 1100 Gallon Vertical Water Storage Tank in black is a polyethylene vertical storage tank built for bulk water on a compact pad: 87 inches in diameter and 53 inches tall, it holds 1,100 gallons in a footprint just over seven feet square (87 x 87 inches). The black resin blocks light to slow algae growth in standing water, which makes this a practical choice for rural water storage, irrigation supply, rainwater collection, and fire-reserve duty where a tidy, low-profile vertical tank matters.
Will it work for your site?
This is a 1.1 specific-gravity-rated tank, sized for water and other fluids up to that density. Plan your pad around the loaded weight, not the empty shell: filled to 1,100 gallons of water this tank carries roughly 9,174 pounds of contents, and its maximum rated contents weight is 10,091 pounds. That 10,091-pound figure is the number your foundation has to support. The tank needs a level, fully supporting base across the entire 87 x 87-inch footprint - a continuous concrete pad or compacted sand bed, never point supports or a partial ring. Run the numbers for your exact fill level and fluid with the Tank Sizing Calculator, and if you are deciding between capacities, the Tank Sizing Guide walks through the trade-offs. For acceptance after install, our hydrostatic test methodology guide covers water-fill discipline and pad-settlement monitoring as you bring it up to level.
Plan the pad before delivery
A vertical water tank this size lives or dies on its foundation. Because the full contents weight reaches 10,091 pounds, the pad has to be engineered, not improvised - see our walkthrough on concrete pad sizing for above-ground polyethylene tanks for the ACI 360R-10 framework. If this tank is part of a private fire-protection plan, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. For greywater, rainwater, and HVAC-condensate aggregation, our water-reuse tank topology guide shows where a tank this size fits in a banded storage train.
The mistake to avoid
The most common error on a tank this size is treating its 1.1 specific-gravity rating as a license to store anything liquid. It is rated to 1.1 SG, which covers water and lighter fluids; the rating applies to the tank shell, and for anything beyond water, fitting and gasket material compatibility is a separate check you have to make before filling. For products denser than water, call 866-418-1777 and we will match you to the correct higher-SG tank rather than risk this one. The second mistake is the pad: set this tank on uneven ground or partial supports and the polyethylene shell will flex and fatigue under that 10,091-pound load. Support the full base, keep it level, and confirm the inlet, outlet, and lid configuration against the technical drawing on this page matches your plumbing plan before you set it - call 866-418-1777 if you need the fitting schedule.
