The Norwesco 10500 Gallon Black Vertical Storage Tank (SKU 47638B) is a top-of-range bulk water option: 10,500 gallons in a black polyethylene vertical body standing 202 inches tall on a 130 x 130-inch footprint. The black wall blocks light to suppress algae growth in stored water, which makes this tank a strong fit for outdoor irrigation reserve, rainwater capture, rural fire-water reservoirs, and industrial process and reuse water. It carries a 1.5 specific gravity rating, meaning the wall is engineered to safely hold contents up to 1.5 times the density of water.
Will it work for your site
Plan the pad before the tank. Filled with water this Norwesco vertical storage tank weighs roughly 87,570 lb, and at its full 1.5 SG rating it can carry up to 131,355 lb of contents. That load lands inside a 130 x 130-inch footprint, so the supporting surface has to be engineered for it - a tank this size belongs on a properly sized, level concrete pad, not bare soil or gravel. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. Because this is a 202-inch outdoor vertical, factor cold-climate siting into both the pad and your draw planning as well. Read the inlet, outlet, and any vent or manway location and size off the technical drawing on this page before you set anchors or plumb connections - the drawing is the dimensional source of record for this tank, and connection sizes are not yet listed in the spec table here, so do not assume a fitting set based on the table alone.
Sizing it right
At 10,500 gallons this Norwesco tank sits at the top end of the bulk water range, so confirm the volume actually matches your draw and refill cycle before committing to a tank this large. The Tank Sizing Calculator and Tank Sizing Guide help you match capacity to demand. If this is a rural or remote fire-protection reserve, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the industrial water reuse topology guide shows where a tank this size fits in a quality-banded storage train, and if you are catching roof runoff, the rainwater harvesting and first-flush guide covers diverter sizing for clean capture into a tank this size.
The mistake to avoid
The most common error on a tank this size is underbuilding the foundation. Empty, a poly vertical tank is easy to move; once you put 87,570 lb of water in it, any settling, slope, or soft spot under the pad turns into stress on the tank wall. Pour and cure a pad rated for the full filled weight, confirm it is dead level, and never partially support the base. Treat the 1.5 SG rating as a ceiling, not a target - it is the maximum content density the wall is built for, and water itself sits well under it. One upside of that over-spec rating: because the wall is built to 1.5 SG, this same tank also handles denser-than-water fluids common in industrial reuse and process duty, up to that 1.5 ceiling, so it covers heavier service classes you may grow into.
This vertical storage tank ships LTL freight from the Norwesco plant in Albertville, AL, quoted live to your ZIP. A 202-inch-tall tank of this size needs equipment-assisted offload at delivery, so plan rigging in advance.
