The Norwesco 2500 gallon green vertical water storage tank is a California-only color build for above-ground bulk water storage. It holds 2,500 gallons in a single upright cylinder that stands 79 inches tall on a 102 by 102 inch footprint, so this is a relatively wide, low-profile vertical tank rather than a tall narrow one. The shell is molded polyethylene rated to a specific gravity of 1.0, which means it is built for water and water-density liquids, not heavier chemical contents. If you have been searching for a Norwesco water storage tank or a vertical storage tank for ranch, fire-reserve, irrigation, or general water-storage duty, this is the size that bridges household-scale and true bulk capacity.
Will it work for your site?
Plan around the loaded weight, not just the empty shell. Filled to capacity with water, this tank carries roughly 20,850 pounds of contents, its maximum rated contents weight at SG 1.0. That number drives your pad design. A 102 by 102 inch footprint concentrates more than ten tons onto a four-foot-square area, so the base has to be flat, level, and fully supporting across the entire bottom. For getting the pad right, see our concrete pad sizing guide built around the ACI 360R-10 framework. If you are still confirming that 2,500 gallons is the right capacity for your draw and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. Review the technical drawing on this page for the full dimensional layout before you pour anything.
Confirm fittings and color before you order
No inlet, outlet, vent, or manway configuration is specified for this listing, so confirm the fitting size, thread type, and gasket material you need before you order rather than assuming a standard outlet is included. A quick call settles it. Because the green color on this model is a California-only build, paired with California ship points, confirm it is the correct match for your in-state site; out-of-state buyers should verify color availability before assuming green ships nationwide. For fire-water reservoir duty, our fire-water reservoir design guide walks through NFPA 22 sizing discipline and freeze protection for cold-climate sites, and if you are aggregating grey water, rainwater, or HVAC condensate into a reuse train, the water reuse tank topology guide covers quality-banded storage architecture. After installation, fill and prove the tank with a controlled water test; our hydrostatic test methodology guide covers fill discipline, pad-settlement monitoring at the full 20,850 lb load, and hold-time math so you catch any issue before the tank is in daily use.
The mistake to avoid
The most common error on a water tank like this is treating the SG 1.0 rating as a suggestion. This shell is engineered for water-density liquids. Storing anything heavier than water without moving to a tank built for a higher specific gravity overloads the wall, and no pad design compensates for an under-rated shell. Keep this tank on water and water-equivalent contents, and match heavier liquids to a tank specifically rated for them.
This tank ships by LTL freight, quoted live to your ZIP code. It ships from a California Norwesco plant in Hanford, CA (with Merced, CA as the other California ship point), which keeps transit short and freight reasonable for California destinations.
