The Norwesco 4200 Gallon Black Vertical Storage Tank (SKU 42020) is a heavy-duty, large-volume polyethylene vertical tank built for bulk water storage on farms, ranches, rural fire-protection sites, and industrial water-reuse systems. It stands 131 inches tall on a 102 x 102-inch footprint, holds 4,200 gallons, and carries a 1.5 specific gravity rating, meaning the tank wall is engineered to handle contents heavier than water. The black polyethylene blocks light, which helps slow algae growth in stored water compared with a translucent shell.
Will it work for your site?
This is a large, free-standing vertical storage tank, so plan the foundation around the loaded weight, not the empty shell. Filled with water, the tank and contents weigh roughly 35,028 pounds; at the maximum rated contents weight on the 1.5 specific gravity rating, that figure climbs to about 52,542 pounds. Those numbers drive your pad design more than any other spec, so size the slab to the full load before you order. The 102 x 102-inch footprint and 131-inch height also set your clearance for filling, venting, and overhead access. If you are still working out whether 4,200 gallons matches your demand, the Tank Sizing Calculator and the Tank Sizing Guide walk through draw-down rates and reserve volume so you land on the right Norwesco vertical storage tank the first time.
Fittings and common uses
For outlet, vent, and fitting placement, see the technical drawing on this page; because configurations on a vertical storage tank of this size can vary, call 866-418-1777 to confirm the exact fitting layout before you order, and make sure any fittings and gaskets you connect are rated for your stored fluid and 1.5 SG service. At 4,200 gallons, this black Norwesco tank is a common reservoir choice for rural and remote fire-water storage, agricultural water supply, and aggregated water-reuse trains. If you are specifying it for private fire protection, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing and freeze protection for cold-climate service. For greywater, rainwater, and HVAC condensate aggregation, see our breakdown of industrial water-reuse tank topology, and if you are pairing this tank with roof catchment, our rainwater harvesting first-flush diverter guide covers keeping debris out of stored water.
The mistake to avoid
The most common error on a tank this size is under-building the foundation. At a full water weight near 35,028 pounds and a maximum rated load around 52,542 pounds, an undersized or uneven pad can settle, stress the tank wall, and shorten service life. Pour a level, properly sized slab rated for the full load before delivery, and review our concrete pad sizing guide for above-ground polyethylene tanks first.
